When not in use, the serial port should be covered.
If error conditions are encountered, they are displayed on the local RS-232 serial port after the switch completes the POST. See “errShow” in Chapter 4 for details. Setting IP Address Using the Serial Port There is a label on the front panel of the PowerVault 51F switch with space to include the IP address after it has been configured. NOTE: This label facilitates identification of the physical switch in maintenance mode. To enable a connection to the switch, the switch must have a valid IP address set.
Fibre Channel Subnetmask [current]: [enter new subnet mask if needed] Gateway Address [current]: [enter new address if needed] If the current value is acceptable, press . Following entry of these values, the switch can now be accessed via the network connection on the switch. The switch can be managed using Telnet commands. Resetting Factory Defaults In the event that a user changes a password or IP address, or forgets it, or sets an invalid IP address, the IP address can be reinitialized.

NOTES: Except for unique identifiers such as the switch name, domain name, and IP address, all switches in a fabric must have the same firmware configuration. Switches that are configured differently are isolated from the fabric.
FILE LOCATION: S:\SYSTEMS\Boxer\rev_i&t\English\50UWDa00\50UWDc20.fm NOTES: The translative mode is automatically enabled with the FL_Port card and no user intervention is necessary to configure the translative mode. Loops may contain any combination of public or private loop devices. Sample Fabric Topologies The following fabric topology samples show several different conceptual topology models.
FILE LOCATION: S:\SYSTEMS\Boxer\rev_i&t\English\50UWDa00\50UWDc20.fm Figure 2-1 shows the switch’s F_Ports and FL_Ports and the corresponding N_Port and NL_Port connections on the device side. The switch connections are shown as they would be in a physical installation. Functionally, the switch becomes a fabric with every device connected to every other device by the fabric.
FILE LOCATION: S:\SYSTEMS\Boxer\rev_i&t\English\50UWDa00\50UWDc20.fm Increasing Local Bandwidth Within the Fabric In Figure 2-2, three connections are shown between Switch A and Switch B. This connection gives an aggregate bandwidth of six Gbps—in other words, three 1-Gbps, full-duplex connections. Increasing bandwidth between switches is done by adding additional connections between the switches.

CHAPTER 3 Managing the PowerVault 51F Switch This chapter contains general information and examples on managing and monitoring the switch.
Before changing any of the factory default settings, become familiar with the operations described in this chapter including both the switch’s functions and interactive characteristics. To reset a switch to factory default values, see “Resetting Factory Defaults” in Chapter 1. There are several access methods for managing a switch. Table 3-1 summarizes the different management methods. Table 3-1.
Management Information Management Commands SNMP Manage Node Web Telnet HTTP SNMP UDP TCP IP Over Ethernet Ethernet (Out-of-Band) RS-232 Port Figure 3-1. Switch Management Methods Managing Via Telnet To make a successful Telnet connection to a switch, the following information is required: • • • Switch name or IP address Username Password NOTES: The IP address must be set using the ipAddrSet command, which can be issued by connecting to the RS-232 serial port on the front panel.
Default Username Each Username has a security level associated with it. Username 3 is the least privileged and the security level goes up to Username 0, which is the most privileged, as described in Table 3-2. Table 3-2. Default Username Default User Name Description user (Username 3) Gives users access to any commands that do not change a switch state, such as version. This level is the recommended level for monitoring switch activity.
Dell recommends that you use one of the “ro” communities to set up your trap community and trap recipients IP address. Also, the administrator of the switch may want to rename the default communities to a unique secure name. The resident SNMP manage node allows remote switch management via IP over Ethernet and Fibre Channel interfaces. Dell OpenManage integrates the PowerVault 51F switch through HP OpenView Network Node Manager Special Edition (NNM SE) in a Microsoft® Windows NT® environment.
Fabric Element MIB Support The following five object groups are defined and supported: • • • • • Configuration group Operation group Error group Accounting group Capability group The agent supports all groups, except the accounting group, which is better supported in the Fibre Channel port group of the vendor-unique MIB.
Enterprise Specific Traps The following Enterprise Specific Traps are supported: • • • • swFault — Indicates the diagnostics detect a fault with the switch. swSensorScn — Indicates an environment sensor changes its operational state. For example; a fan stops working. The VarBind in the Trap Data Unit contains the corresponding instance of the sensor status. swFCPortScn — A notification that a Fibre Channel Port changes its operational state.
2 — Error 3 — Warning 4 — Informational 5 — Debug See Appendix A, “Error Messages,” for more information. These parameters can be changed via the Telnet command, agtcfgSet or via SNMP. The sysX parameters can be configured via the SNMPv1 SET command with an appropriate community. These parameters can be configured via a Telnet connection, using the command agtcfgSet. NOTE: A change in the first two configuration parameters takes effect only after rebooting the switch.
Introducing the PowerVault Switch Manager Use the PowerVault Fibre Channel Switch Manager (Web interface) to log onto a switch from a host with a Java-enabled Web browser via the Internet or Intranet to remotely manage a storage area network (SAN) composed of switches and other SAN devices. The PowerVault Fibre Channel Switch Manager allows you to dynamically interact with any switch in the SAN to monitor status and performance.

CHAPTER 5 Troubleshooting This chapter discusses troubleshooting, diagnostic testing, and error messages, including the following sections: • • Diagnostic overview Status and activity indicators Diagnostic Overview The switch is designed for maintenance-free operation. When there is a suspected failure, the switch has self-diagnostic capabilities to aid in isolating any equipment or fabric failures. The switch supports power-on self-tests (POSTs) and diagnostic tests.
To retest a port which has been marked BAD, clear the port and set to OK using the diagClearError (port#) command. This command clears the port status only and does not clear the logs or change the port’s condition. The diagClearError (port#) command should only be used during diagnostic procedures to reset a bad port for re-test. For more detailed error message information, see Appendix A, “Error Messages.
Table 5-1. Front-Panel LED Status Indicators Front-Panel LEDs Definition No light showing Power not applied. Steady power LED Normal power-on indicator. Flashing power LED Switch failed POST and is not functioning, although power is applied. Front-Panel LED Port Indicators The color and flash speed of each port’s LED, as described in Table 5-2, indicates the individual port’s status. Table 5-2.
7. Fabric analysis; the switch checks for ports connected to other fabric elements. If there are other fabric elements connected, it identifies the master switch. 8. Address assignment; after the master switch is identified, port addresses may be assigned. Each switch tries to keep the same addresses that were previously used. These are stored in the switch’s configuration flash PROM. 9. Routing table construction; after addresses are assigned, the Unicast routing tables are constructed. 10.
CHAPTER 6 Repair and Replacement This chapter covers the recommended and supported field repair and replacement for the PowerVault 51F switch.
