6.1.3 I/O module management tasks
In this section, we set up and configure the Cisco Systems IGESM.
IGESM setup and configuration
The IGESM can be installed into any of the four BladeCenter switch bays in the rear of the
chassis. Bay 1 is attached to one of the Ethernet Network Interfaces Controllers (NIC) on the
blade HS20. Bay 2 is attached to the other Ethernet NIC. Each NIC is a Gigabit Full Duplex
link to only one of the switches. As for HS40, which has a total of four NICs as standard, each
two NICs link to one switch. A switch in bay 3 or bay 4 is required when a Gigabit Ethernet
Expansion Card is being installed on the blade. This card provides an additional two NICs to
the blades. One of the NICs has a dedicated Gigabit Full Duplex link to bay 3 and the other
NIC to bay 4. To manage the Cisco Systems Intelligent Gigabit Ethernet Switch Module in
bay 1: From the BladeCenter Management Module, click I/O Module Tasks
→ Management.
A window similar to the one in Figure 6-4 opens.

As with the Management Module, the switch must have a unique IP address and be on the
same subnet as the Management Module for out-of-band management (5.2.1, “Out-of-band
management definition” on page 40). Enter a Gateway address if attaching to other networks
is required. If in-band management (5.2.2, “In-band management definition” on page 41) is
desired, the IP address must be in a different subnet than the Management Module. In
addition, when in-band management is configured, you must ensure that the VLAN that is
configured on the switch is carried on the IGESM’s uplinks.
See 5.3, “In-depth management path discussions” on page 55 for details about selecting and
configuring for in-band (IGESM management via the IGESM uplinks) or out-of-band (IGESM
management via the Management Module uplink).
