Introduction Additional references Configure the switch after installation. Detailed information about how to configure the switch is available in the reference guides listed below. To obtain these guides, see the HP website (http://www.hp.com/go/bladesystem/documentation).
• Support for Telnet, SNMP, SCP, FTP, and TFTP file transfer, human read/write configuration file, XModem, and an extensive list of MIB objects further enhance the management capabilities • Fully redundant end-to-end architecture maximizing server availability from the network • Support for IGMP snooping for multicasting • Support for UFD for network path resiliency. It works in conjunction with NIC teaming functionality that is supported on the blade servers.
• Up to two separate switches in slots 5 and/or 7 per one HP c-7000 BladeSystem server blade enclosure • Four, ten Gigabit Ethernet uplink ports (ports 18-21), per switch, for designing fully meshed uplink paths to the network backbone • Server networking connections routed to each of the separate switches for redundant paths to tolerate a switch or port malfunction • STP support that eliminates potential problems caused by redundant networking paths and provides for failover with a secondary path in
Diagnostic tools The hardware, software, and firmware diagnostic tools that are available include: • HP Systems Insight Manager automatic discovery and identification • POST built into the switch boot process • Switch port mirroring • Switch LED panel displaying per port status and speed • System, management, and option compatibility status LEDs • Rear panel reset power switch and DB-9 management serial port • Statistic monitoring including port utilization, data packets received/transmitted,
Redundant Ethernet signals from each blade server are routed through the enclosure backplane to separate switches within the enclosure. However, specific switch port to server mapping varies depending on which type of server blade is installed. Supported technologies Layer 2 switching The switch uses Gigabit Layer 2 switching technology. Layer 2 refers to the Data Link layer of the OSI model, which is concerned with moving data packets across a network by enforcing CSMA/CD.
IMPORTANT: The greater the number of VLANs, the greater the switch CPU utilization. For maximum switch performance, HP recommends being judicious when configuring the number of VLANs. NOTE: VLAN 4095 is reserved for future functionality. Spanning Tree Protocol The switch supports IEEE 802.1D STP, which allows the blocking of links that form loops between switches in a network. When multiple links between switches are detected, a primary link is established.
TFTP support TFTP support allows the switch firmware to be upgraded by downloading a new firmware file from a TFTP server to the switch. Firmware images of the switch are also uploaded to a TFTP server, a configuration file is downloaded into a switch from a TFTP server, and configuration settings are saved to the TFTP server. Store and forward switching scheme The switch provides a store and forward switching scheme that allows each packet to be buffered (stored) before it is forwarded to its destination.
• Authorization of remote administrators • Determination of the permitted actions and customizing service for individual administrators TACACS+ The switch supports the TACACS+ method to authenticate, authorize, and account for remote administrators managing the switch. This method is based on a client/server model. The switch is a client to the back-end TACACS+ AAA server. A remote user (the remote administrator) interacts only with the client, and not with the back end AAA server.
IGMP Snooping The switch supports IGMP Snooping for multicasting. Version 1-, Version 2-, and Version 3-based IGMP Snooping are supported. In addition, auto detection of the multicast router port and manual configuration of the multicast router port is supported. For efficient multicast traffic management, the IGMP Filtering option is supported. Jumbo frames By default, the switch supports jumbo frames up to 12 KB, which help reduce server CPU utilization and increase application throughput.
Component identification 10Gb Ethernet BL-c Switch front panel CAUTION: Pressing the Reset button while the Health LED is green resets the switch. Item Description 1 UID LED 2 Health LED • Off—Not powered up • Green—Powered up and all ports match • Amber—Indicates a problem such as a port mismatch. For more information, see the HP BladeSystem enclosure quick setup instructions.
Installing the switch Preparing for installation IMPORTANT: Before installing the switch, make a record of the MAC address (printed on the MAC address label attached to the switch). This address is needed when configuring the switch. Planning the switch configuration The switch ships with a default configuration in which all downlink and uplink ports are enabled and assigned a default VLAN with a VID equal to 1.
• User name and password settings • Default access to various management interfaces • NTP settings IMPORTANT: See "Runtime switching software default settings (on page 29)" for a complete list of default configuration settings.
User account Description and tasks performed Password User The user has no direct responsibility for switch management. He or she user can view all switch status information and statistics, but cannot make any configuration changes to the switch. Operator The operator manages all functions of the switch. The operator can reset ports or the entire switch. By default, the operator account is disabled and has no password.
Installing the switch CAUTION: Do not cable the switch until after configuration. IMPORTANT: Make sure that the server NIC configuration matches the switch bay selected. IMPORTANT: For the HP BladeSystem c7000 Enclosure, the switch can only be installed in bays 5/6 or 7/8. For the HP BladeSystem c3000 Enclosure, the switch can only be installed in bays 3/4. 1. Remove the interconnect blank. 2. Remove the divider.
3. Install the switch. A successful installation is indicated by a green Health LED. If the Health LED is amber or power is not applied to the switch, see the "Troubleshooting" section of the HP BladeSystem enclosure setup and installation guide for more information. For a cabling diagram, see the HP BladeSystem enclosure setup and installation guide. Accessing the switch The switch is accessed remotely using the Ethernet ports or locally using the DB-9 management serial port.
1. Access the switch ("Accessing the switch" on page 20). After connecting to the switch console, the login prompt appears. 2. Enter admin as the default administrator password.
1. Remove the dust plug and save for future use. IMPORTANT: Use only XFP transceivers purchased from HP. 2. Insert the XFP transceiver. With latch closed, be sure that the transceiver is fully seated and securely in place. 3. Enable the switch port. Supporting software and special considerations Supporting software is available to assist in configuring and managing the switch.
Replacing a switch Replacing an existing switch CAUTION: Removing the switch from a powered enclosure results in the loss of network communications between the server blade network ports that are connected through this switch and the segment of network infrastructure those ports need to communicate.
6. If the configuration file was saved to a TFTP server, download the configuration. For more information on downloading a configuration file, see the HP 10Gb Ethernet BL-c Switch Command Reference Guide.

SNMP MIBs support MIB overview Management and statistics information is stored in the switch in the MIB. The switch supports several standard MIBs. Values for MIB objects are retrieved with any SNMP-based network management software. In addition to the standard MIBs, the switch also supports its own proprietary enterprise MIB as an extended MIB. The proprietary MIB is retrieved by specifying the MIB OID at the network manager station. MIB values are either read-only or read/write variables.

Electrostatic discharge Preventing electrostatic discharge To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device. To prevent electrostatic damage: • Avoid hand contact by transporting and storing products in static-safe containers.
Troubleshooting Forgotten administrator user name and password that was configured on the switch Action: Call HP technical support at 1-800-652-6672, or call a service representative to get a backdoor password. Health LED on the switch is not on Action: • The switch is not seated properly. Be sure that the switch is inserted completely and seated properly. • The server blade enclosure is not powered up. Be sure that the server blade enclosure is powered up and all the power connections are intact.
Error message that the switch failed to complete the system self-testing appears on the serial console screen Action: The system diagnostic tests failed. Note the reason for the failure from the serial console screen message and call a service representative. The switch fails to get its IP settings from the BOOTP server, even though by default it is configured for BOOTP Action: • The switch is not connected properly to the network.
• The setting allowing access to the switch using the Telnet interface is disabled. From the serial console interface, be sure that the Telnet interface is enabled. • The management network address/mask (if used) does not contain the IP address of the management station. From the serial console interface, be sure that the Management Network Address/Mask contains the IP address of the management station.
The port activity LEDs continuously indicate activity after connecting more than one port to another switch or destination device Action: Because there are multiple links across this device and the destination device, they form loops, which cause broadcast storms. Enable STP for multiple links. This setting prevents loops and maintains standby links for resilience in case of primary link failure.
The switch does not let the user enable two adjacent ports into two different VLANs while assigning the ports to VLANs Action: The ports are two adjacent ports that are bundled in a Port Trunk. Two ports that are assigned to a Port Trunk cannot be assigned to two different VLANs. Either break the trunk to assign it two different VLANs or assign the ports to one VLAN.
• o Be sure that a valid configuration file exists on the TFTP server to download to the switch. o On the switch, check the file name configured to download or upload. The TFTP server was started with a configured directory. The switch must be configured using the full path name, if it is not in the directory specified in the TFTP server.
• Enable the switch port after inserting the HP authorized XFP transceiver.
