Mounting OS6250 Switches General Installation Recommendations General Installation Recommendations Cooling Recommendations OS6250 non-PoE switches are convection-cooled. Although air flow is not mandatory for switch operation, the best way to ensure proper cooling is to provide some ambient air flow over the switch whenever possible (e.g., from room fans, etc.). See table below for recommended clearance above the chassis.
General Installation Recommendations Mounting OS6250 Switches Reduced Air Flow Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. Elevated Operating Ambient Temperatures If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient.

4 Booting 6250 Switches For information on booting stand-alone switches and switches in stacked configurations, refer to the sections below. Booting an OmniSwitch 6250 The OmniSwitch 6250 switch does not use an on/off switch. The power cord is the switch’s only connect/ disconnect device. The power connector socket is located on the power supply rear panel. For more information, refer to “OmniSwitch 6250 Chassis and Hardware Components” on page 2-1.
Console Port Booting 6250 Switches Console Port The console port, located on the chassis front panel, provides a console connection to the switch and is required when logging into the switch for the first time. By default, this RJ-45 connector provides a DTE console connection.
Booting 6250 Switches Console Port 5 To change the stop bits value, enter boot serialstopbits, followed by the number of stop bits. Options include 1 (default) and 2.
Console Port Booting 6250 Switches Viewing the Power Supply Status The switch constantly monitors the power supply operation. If either the primary or backup power source (optional) unexpectedly shuts down, the switch sends out a notification to the user. In addition, the power LED on the chassis front panel displays solid amber. Note. For detailed OmniSwitch 6250 LED information, refer to “LED Status” on page 2-20.
Booting 6250 Switches Monitoring the Chassis Monitoring the Chassis OmniSwitch 6250 switches can be monitored and managed via the console port using Command Line Interface (CLI) commands. The switches can also be monitored and managed via the Ethernet using CLI commands, WebView, SNMP, and OmniVista.

5 Managing Power over Ethernet (PoE) Power over Ethernet (PoE) is supported on OmniSwitch 6250 switches and provides inline power directly from the switch’s Ethernet ports. Powered Devices (PDs) such as IP phones and wireless APs can be powered directly from the switch’s RJ-45 ports. As the feature reduces devices’ dependence on conventional power sources, PoE eliminates many restrictions that traditional electrical considerations have imposed on networks.
In This Chapter Managing Power over Ethernet (PoE) In This Chapter This chapter provides specifications and descriptions of hardware and software used to provide PoE for attached devices. The chapter also provides information on configuring PoE settings on the switch through the Command Line Interface (CLI). CLI commands are used in the configuration examples; for more details about the syntax of commands, see the OmniSwitch CLI Reference Guide.
Managing Power over Ethernet (PoE) Power over Ethernet Specifications Power over Ethernet Specifications The table below lists general specifications for Alcatel-Lucent’s Power over Ethernet support. For more detailed power supply and Power Source Equipment (PSE) specifications, refer to Chapter 2, “OmniSwitch 6250 Chassis and Hardware Components.” IEEE Standards supported IEEE 802.3af; 802.
Viewing PoE Power Supply Status Managing Power over Ethernet (PoE) Viewing PoE Power Supply Status To view the current status of power supplies installed, use the show power command, as shown below: -> show power Slot PS Wattage Type Status Location ----+----+---------+------+-----------+---------1 1 225 AC UP External 1 2 225 AC UP External 2 1 225 AC UP External 2 2 225 AC UP External For detailed information on the show power command output, refer to the CLI Command Reference Guide.
Managing Power over Ethernet (PoE) Configuring Power over Ethernet Parameters Configuring Power over Ethernet Parameters Power over Ethernet Defaults The following table lists the defaults for PoE configuration: Parameter Description Command(s) Default Value/Comments PoE operational status lanpower start or lanpower stop Disabled Total power available to a port lanpower power 16 Watts (802.3af) 31 Watts (802.
Configuring Power over Ethernet Parameters Managing Power over Ethernet (PoE) Disabling PoE To disable PoE on a particular slot or port, use the lanpower stop command. To disable PoE on a specific PoE-capable port, enter a slot/port number. For example: -> lanpower stop 1/4 To disable PoE for all PoE-capable in a slot, enter the corresponding slot number only.
Managing Power over Ethernet (PoE) Configuring Power over Ethernet Parameters Important. Before changing the maximum slot-wide power allowance, you must disable PoE for the slot via the lanpower stop command. Once the new value is assigned, re-enable PoE for the slot via the lanpower start command. To increase or decrease the total power available to a slot, use the lanpower maxpower command.
Understanding Priority Disconnect Managing Power over Ethernet (PoE) Understanding Priority Disconnect The priority disconnect function differs from the port priority function described on page 5-7 in that it applies only to the addition of powered devices (PDs) in tight power budget conditions. Priority disconnect is used by the system software in determining whether an incoming PD will be granted or denied power when there are too few watts remaining in the PoE power budget for an additional device.
Managing Power over Ethernet (PoE) Understanding Priority Disconnect Priority Disconnect is Enabled; Same Priority Level on All PD Reminder. Priority disconnect examples are applicable only when there is inadequate power remaining to power an incoming device. When a PD is being connected to a port with the same priority level as all other in the slot, the physical port number is used to determine whether the incoming PD will be granted or denied power.
Understanding Priority Disconnect Managing Power over Ethernet (PoE) When a PD is being connected to a port with a lower priority level than all other in the slot, the incoming PD will be denied power, regardless of its physical port number. Devices connected to other higher-priority will continue operating without interruption. Priority Disconnect is Disabled Reminder. Priority disconnect examples are applicable only when there is inadequate power remaining to power an incoming device.

6 Managing OmniSwitch 6250 Stacks In addition to their working as individual stand-alone switches, OmniSwitch 6250 switches can also be linked together to work as a single virtual chassis known as a stack. With stacks, users can easily expand their switching capacity simply by adding additional switches to the stack. In addition, stacks provide enhanced resiliency and redundancy features. For more information, refer to page 6-4.
In This Chapter Managing OmniSwitch 6250 Stacks In This Chapter This chapter provides information on OmniSwitch 6250 switches configured to operate as a single virtual chassis. Topics described in the chapter include: • OmniSwitch 6250 stack overview on page 6-4. • Roles within the stack on page 6-4. • Stack cabling on page 6-17. • Slot numbering on page 6-20. • Hot-Swapping modules in a stack on page 6-25. • Reloading switches on page 6-27. • Changing the secondary module to primary on page 6-35.
Managing OmniSwitch 6250 Stacks OmniSwitch 6250 Stacking Specifications OmniSwitch 6250 Stacking Specifications The following table lists OmniSwitch 6250 Stacking specifications.
OmniSwitch 6250 Stack Overview Managing OmniSwitch 6250 Stacks OmniSwitch 6250 Stack Overview Users can configure OmniSwitch 6250 switches into a single virtual chassis known as a stack. With stacks, switching capacity can be easily expanded simply by adding additional switches to the stack. For example, a user can start with a stack composed of two switches and add additional switches to that stack as network demands increase over time. Note. Switches should be added one at a time in a stack.
Managing OmniSwitch 6250 Stacks Roles Within the Stack Important Note. For management module redundancy to work effectively, the software on all switches operating in the stack must be synchronized at all times. Refer to “Synchronizing Switches in a Stack” on page 6-37 for more information. Primary 1 A stack of four OmniSwitch 6250 switches is operating normally. The stack consists of a primary module, secondary module, and two elements operating in idle status.
Roles Within the Stack Managing OmniSwitch 6250 Stacks 1 A stack of two OmniSwitch 6250 switches is operating normally. The stack consists of a primary module and a secondary module. (The software on both elements in the stack is synchronized.) 2 The primary management module fails or is taken offline (e.g., powered off or rebooted by the user). 3 The switch operating as the secondary management module immediately takes over the primary role.
Managing OmniSwitch 6250 Stacks Roles Within the Stack Primary Management Module Selection For a stack of OmniSwitch 6250 switches to operate as a virtual chassis, there must be a mechanism for dynamically selecting the switch within the stack that will assume the primary management role. OmniSwitch 6250 switches use three different methods for selecting the primary switch. These methods are: • Chassis MAC address • Saved slot number • Chassis uptime Note.
Roles Within the Stack Managing OmniSwitch 6250 Stacks Using Saved Slot Information The saved slot number is the slot number the switch will assume following a reboot. This information is stored in a switch’s boot.slot.cfg file; the switch reads its slot number assignment from this file at bootup and assumes the specified slot number within the stack.
Managing OmniSwitch 6250 Stacks Roles Within the Stack Using Switch Uptime A user can override both the MAC address and saved slot methods for determining a stack’s primary management module. This is done by controlling the uptime of switches in the stack. If all elements of a stack are powered off, the user can force a particular switch to become primary by powering on that switch and waiting a minimum of 15 seconds before powering on any other switches.
Roles Within the Stack Managing OmniSwitch 6250 Stacks Secondary Management Module Selection In order to provide effective management module redundancy, all OmniSwitch 6250 stacked configurations dynamically assign a backup, or secondary, management module during the boot process. OmniSwitch 6250 stacks use two different methods for selecting the secondary switch.
Managing OmniSwitch 6250 Stacks Roles Within the Stack Using Saved Slot Information If a stack with preassigned slot information for each switch is booted, the switch with the second lowest slot value is assigned the secondary management role. For example, if a stack of four switches is booted and the preassigned slot values for each switch are 1, 2, 3, and 4, the switch with the slot value of 2 is assigned the secondary role.
Roles Within the Stack Managing OmniSwitch 6250 Stacks Idle Module Role Switches that are not assigned either the primary or secondary role in a stack are, by default, assigned the role of idle modules. These idle modules operate similarly to Network Interface (NI) modules in a chassisbased switch. It is the job of idle modules to send and receive traffic.
Managing OmniSwitch 6250 Stacks Roles Within the Stack Pass-Through Mode The pass-through mode is a state in which a switch has attempted to join a stack but has been denied primary, secondary, and idle status. When a switch is in the pass-through mode, its Ethernet ports are brought down (i.e, they cannot pass traffic). Its stacking cable connections remain fully functional and can pass traffic through to other switches in the stack.
Roles Within the Stack Managing OmniSwitch 6250 Stacks To avoid a pass-through condition following a reboot, make sure that all saved slot values for the stack are unique. Use the stack set slot command.
Managing OmniSwitch 6250 Stacks Roles Within the Stack To resolve this pass-through condition, simply assign slot 1001 a new saved slot value and reboot the module.
Roles Within the Stack Managing OmniSwitch 6250 Stacks In some pass-through conditions (for example, larger stacks where multiple switches are in pass-through mode), it might be desirable to correct any duplicate saved slot assignments and then reboot the entire stack. The recovery from pass-through can be accomplished with fewer steps than reassigning slot numbers and rebooting modules on a slot-by-slot basis.
Managing OmniSwitch 6250 Stacks Stack Cabling Stack Cabling Switches in a stack are connected to each other by stacking cables. These stacking cables provide highspeed, dual-redundant links between switches in a stack. Stacking cables for OmniSwitch 6250 switches must be connected in an A-B pattern. In other words, the cable connected to stacking port A of one switch must be connected to stacking port B of the adjacent switch.
Stack Cabling Managing OmniSwitch 6250 Stacks Redundant Stacking Cable Connection OmniSwitch 6250 switches allow redundant stacking cable connections between the top-most and bottommost switches in a stack. Important. For a stacked configuration to have effective redundancy, a redundant stacking cable must be installed between the upper-most and bottom-most switch in the chassis at all times.
Managing OmniSwitch 6250 Stacks Stack Cabling Redundant stacking cables provide a form of dual redundancy. As shown in the figure above, the redundant cable allows traffic to flow in the event of a stacking link failure. The redundant cable also provides failover if a switch goes down within the stack. Traffic continues to flow between the modules that remain operational, as shown in the diagram below: Stacking Cables Chassis Front Slot 1 1 Data enters slot 1 through an Ethernet port.
Slot Numbering Managing OmniSwitch 6250 Stacks Slot Numbering For a stack of OmniSwitch 6250 switches to operate as a virtual chassis, each module in the stack must be assigned a unique slot number. To view the current slot assignments for a stack, use the show ni or show module commands. The slot number is also displayed on the front panel of each switch by the LED located on the left side of the chassis (refer to “LED Status” on page 2-20 for more information).
Managing OmniSwitch 6250 Stacks Slot Numbering Dynamic Slot Number Assignment Dynamic slot number assignment occurs when there are no boot.slot.cfg files present in the switches’ /flash directories. This is the case for new, “out of the box,” switches that have not been previously booted. When a brand new stack (or stack with no boot.slot.cfg files) is booted, the system software automatically detects the module with the lowest MAC address.
Slot Numbering Managing OmniSwitch 6250 Stacks If the switch with the lowest MAC address happens to be the bottom-most module in the stack, slot numbering will not resume from the top of the stack. Instead, the system software will select the secondary module using the standard method (i.e., the switch connected to the primary’s stacking port A), then continue to number the stack from the bottom up. This intuitive slot assignment provides the cleanest and most manageable stack topology.
Managing OmniSwitch 6250 Stacks Slot Numbering Manual Slot Number Assignment To manually assign slot numbers to one or more modules in a stack, use the stack set slot command. This command writes slot information to the boot.slot.cfg file located in a switch’s /flash directory. It is this saved slot information that the switch will assume following a reboot.
Slot Numbering Managing OmniSwitch 6250 Stacks When the stack comes up following the reboot, the manually-configured slot numbers display as follows: Slot 1 - Primary Slot 2 - Secondary Slot 3 - Idle Slot 4 - Idle Stack Numbering Before Manual Assignment The stack set slot command can also be used to manually correct duplicate saved slot assignments within the stack topology. Refer to pages 6-13 through 6-15 for detailed information. Reverting to the Dynamic Slot Numbering Model To clear the boot.
Managing OmniSwitch 6250 Stacks Hot-Swapping Modules In a Stack Hot-Swapping Modules In a Stack As with chassis-based switches, NI modules within an OmniSwitch 6250 virtual chassis are hot-swappable. NI modules are essentially those modules operating in the stack in idle mode. These modules can be removed from, or added to, an existing stack without disrupting other modules in the stack.
Hot-Swapping Modules In a Stack Managing OmniSwitch 6250 Stacks Merging Stacks Merging stacks involves connecting two or more operational stacks and attempting to reboot them as a single virtual chassis. In most cases, errors will result. To merge stacks without causing errors, select one stack that is to remain up and running and then add modules from the other stack(s) by following the steps below: 1 Make sure all switches are running the same software version.
Managing OmniSwitch 6250 Stacks Reloading Switches Reloading Switches Reloading is essentially a soft boot of a switch. Users can reload stacked modules operating in any role— i.e., primary, secondary, idle, and pass-through. Refer to the sections below for more information. Reloading the Primary Management Module If the switch with the primary management role is reloaded, the switch with the secondary role automatically takes over primary management functions.
Reloading Switches Managing OmniSwitch 6250 Stacks If there are only two switches in the stack, the switch that was reloaded (the former primary) assumes the secondary role when it comes back up. 1 In this stack of two OmniSwitch 6250 switches, the slot 1 switch Primary - Slot 1 is the primary management module. The slot 2 switch is the secondary. Secondary - Slot 2 2 The user reloads the stack’s primary management module by issuing -> reload primary the reload primary command.
Managing OmniSwitch 6250 Stacks Reloading Switches Reloading the Secondary Management Module If the switch with secondary management role is reloaded, the idle switch with the lowest slot number will automatically assume the secondary role. The reloaded switch (the former secondary) will assume an idle role when it comes back up. Meanwhile, the switch with the primary management role, as well as any other idle modules in the stack, continue operations without interruption.
Reloading Switches Managing OmniSwitch 6250 Stacks If there are only two switches in the stack, the switch that was reloaded (the former secondary) resumes the secondary role when it comes back up. Primary - Slot 1 Secondary - Slot 2 1 In this stack of two OmniSwitch 6250 switches, the slot 1 switch is the primary management module. The slot 2 switch is the secondary. 2 The user reloads the stack’s secondary management module by -> reload secondary issuing the reload secondary command.
Managing OmniSwitch 6250 Stacks Reloading Switches Reloading Switches with Idle Roles Similar to reloading Network Interface (NI) modules on chassis-based switches, modules operating in idle status within a stack can be reloaded via the CLI. Note. Any traffic being passed on the module’s Ethernet will be interrupted during the reboot. Other modules within the stack will continue to operate without interruption. To reset a single module operating in idle mode, use the reload ni command.
Reloading Switches Managing OmniSwitch 6250 Stacks Reloading All Switches in a Stack Reloading all switches in the stack is essentially a full reboot of the virtual chassis. This can be useful in restoring a stack’s previously configured topology—i.e., the stack’s saved slot numbers and management roles. Note, however, that all data flow on the stack is interrupted whenever a full reboot is issued. To reset all switches in a stack use the reload all command. For example: -> reload all Important.
Managing OmniSwitch 6250 Stacks Reloading Switches No Switches In the Stack Have Saved Slot Information If a full reload is issued and no switches in the stack have unique slot numbers, slot numbers will be assigned beginning with the switch with the lowest MAC address. (This can occur if the boot.slot.cfg file has been deleted from each switch’s /flash directory—e.g., by issuing the stack clear slot command for all modules in the stack.
Reloading Switches Managing OmniSwitch 6250 Stacks Avoiding Split Stacks The term “splitting” a stack refers to the creation of isolated modules within the virtual chassis. A split stack can result from the following conditions: • Two or more non-adjacent switches are reloaded simultaneously • The stack is reloaded without a redundant stacking cable connection The sections below offer simple guidelines for avoiding splitting the stack during the reload process.
Managing OmniSwitch 6250 Stacks Changing the Secondary Module to Primary Changing the Secondary Module to Primary OmniSwitch 6250 stacks allow users to manually force the secondary switch to assume the primary management role. This is referred to as “takeover.” The behavior of a takeover is similar to that of reloading the primary management module (see page 6-27). Whenever a takeover is initiated, the switch with the secondary role automatically takes over primary management functions.
Changing the Secondary Module to Primary Managing OmniSwitch 6250 Stacks If there are only two switches in the stack, the former primary switch resumes the secondary role when it comes back up following the takeover. Primary - Slot 1 Secondary - Slot 2 1 In this stack of two OmniSwitch 6250 switches, the slot 1 switch is the primary management module. The slot 2 switch is the secondary. 2 A takeover is initiated by the user; the primary management -> takeover module is automatically reloaded.
Managing OmniSwitch 6250 Stacks Synchronizing Switches in a Stack Synchronizing Switches in a Stack Management module synchronization refers to the process of copying all files in the /flash/working and /flash/certified directories of the primary management module to the /flash/working and /flash/certified directories of all the other switches in the stack. The system and configuration software on the nonprimary switches—i.e.
Monitoring the Stack Managing OmniSwitch 6250 Stacks Monitoring the Stack As shown in the previous sections, monitoring the current status and operation of all elements in a stack can help users avoid unexpected stack conditions. The table below includes CLI commands that are useful in monitoring stack conditions. CLI Commands Used for Monitoring a Stack show stack topology Displays the current operating topology of switches within a stack.
Managing OmniSwitch 6250 Stacks Monitoring the Stack CLI Commands Supported on Both Primary and Secondary Management Modules Although most CLI commands are executed when logged into the switch with the primary management role, there is a group of commands that is supported when logged in to either the primary or secondary management module. For a list of these commands, refer to the tables below. Note.
