Cisco Gigabit Ethernet Switch Module for HP BladeSystem p-Class Hardware Installation Guide

Troubleshooting

Replacing an Existing Cisco Gigabit Ethernet Switch Module

CAUTION: Removing a switch from a powered enclosure will result 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.

For continued blade server network communication and services availability, do the following

before you remove the switch. Redirect critical high-availability services or applications to use

the redundant network ports available on those blade servers that are connected through the

redundant switch in the enclosure.

CAUTION: To prevent damage to the cable connectors and SFP modules, be sure to take

the following steps before removing or installing the blade switch:

1. Disconnect the cables from the SFP modules.

2. Remove the SFP modules from the blade switch.

IMPORTANT: If you are replacing an existing CGESM, or upgrading from a GbE2 Interconnect Switch,

a GbE Interconnect Switch, an RJ-45 Patch Panel 2, or an RJ-45 Patch Panel, and you have strict

security requirements:

• Do not cable the switch until after configuration.

• Connect the switch to the optional Diagnostic Station. The Diagnostic Station enables you to power

up, configure, and diagnose a ProLiant p-Class server blade or a switch outside of the rack

environment.

To replace an existing CGESM:

1. If possible, save the configuration file to a TFTP server for later retrieval. For more

information on saving a configuration file to a TFTP server, refer to the Cisco Gigabit

Ethernet Switch Module for HP BladeSystem p-Class Software Configuration Guide

located on the HP website at

http://www.hp.com/support.

2. Disconnect any cables from the SFP modules on the rear side of the switch.

3. Remove the SFP modules.
