You must install switch modules only in switch-module bays 3 and 4 of the SBCE unit. At least one switch
module is required when you install the Fibre Channel Expansion Card in the blade server. Installing a switch
module in bay 3 or bay 4 provides the first connection to any installed Fibre Channel expansion card in the
SBCE unit. Installing a second switch module enables a second connection to a Fibre Channel expansion card
in the SBCE unit. Adding a second switch module provides a redundant path and a separate Fibre Channel
connection from the blade server to the external Fibre Channel network and SAN.
Important:
The switch modules in switch-module bays 3 and 4 and all blade server expansion cards in the SBCE unit must
use the same interface type. Therefore, you must install Fibre Channel expansion cards when you install Fibre
Channel switch modules into your SBCE unit.
The following table summarizes the application for each switch module.

NOTE
The second switch module port connection allows for a redundant path from the blade server to
external Fibre Channel devices.
