LAN-module indicators and input/output connectors
The LAN module is a hot-swap module that is installed on the rear of the
BladeCenter T unit and is held in place by captive thumbscrews. The LAN
module provides the electrical and mechanical interface to the BladeCenter T
unit for the two local area network (Ethernet) connections, as driven from each
management module, and the telco external alarms. This module contains two
RJ-45 connectors with LEDs and one DSUB 15P telco alarm connector.

LAN-module LEDs: These LEDs provide status information about the LAN
connection:
v Ethernet link:
When this green LED is lit, there is an active connection
through the port to the network.
v Ethernet activity: When this green LED is flashing, it indicates that there is
activity through the port over the network link.
LAN-module connectors:
v Remote management and console (Ethernet) connectors: The LAN module
provides two Ethernet RJ-45 connectors.
The BladeCenter T LAN module contains two 10/100 Mb Ethernet
connectors that provide the remote connections, driven from each
management module, to the network management station on the network.
Use these ports for remote management and remote console.
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.
