I/O modules
You can install a maximum of four I/O modules at the rear of the system (a
maximum of four Gigabit Ethernet switches, or a maximum of two Gigabit
Ethernet switches and two Fibre Channel switches). The minimum system
configuration requires one Gigabit Ethernet switch or pass-thru module. The I/O
switch modules provide high-performance connectivity between the blade servers.
See the documentation that comes with each I/O module for a description of the
LEDs and connectors on the I/O module.
BladeCenter T unit power, controls, and indicators
This section describes the controls and light-emitting diodes (LEDs) and how to
start and shut down the BladeCenter T unit.
The network management station, through these connectors, can access control
functions running in the management module, the service processor on each
blade server, or within each switch module. However, it cannot use these ports
to communicate with application programs running in the blade servers. The
network management station must direct those communications through a
network connected to the external ports in the I/O modules in the BladeCenter
T unit.

cable (IBM part number 40K9605).
