Cisco Cisco Catalyst Switch Module 3012 for IBM BladeCenter Installation Guide

This section covers switch module installation. The illustrations in this section show the Catalyst 
Switch Module 3110G as an example. The instructions are the same for the Catalyst Switch 
Module 3110X and 3012.

Consider these guidelines before you install the switch module:

Fill any unoccupied interconnect bays or any unoccupied power module bays in the blade 
enclosure with filler modules.

Identify the bays in which you will insert the switch modules. Plan to install the first switch module 
in bay 1, the second in bay 2, and so on up to bay 4, if possible.

See the IBM blade enclosure documentation for more information about the specific enclosure 
model, the interconnect bay options, and the port mapping between the blade enclosure and the 
switch modules. Also see the blade enclosure compatibility table in the switch module release notes 
on Cisco.com.

Internal 
100BASE-T 
Ethernet port

The Ethernet management port (Fa0) is used only for switch module management 
traffic, not for data traffic. It is connected to the aMM through the blade enclosure 
backplane connector. Traffic to and from this port is isolated from the switch ports. 
This port only supports autonegotiation with 100 Mb/s and full-duplex mode. 

Console port

Switch module management port (USB-to-DB-9 connector).

1. The number of internal ports is determined by the blade enclosure model. See the blade enclosure documentation for 

more information about internal port numbering.
