LAN module indicators and input/output connectors
The LAN module is a hot-swap module located on the back of the BladeCenter T
unit. It provides the electrical and mechanical interface to the BladeCenter T unit for
the two LAN (Ethernet) connections as driven from each management module and
the Telco external alarms. This module contains two RJ-45 connectors with LEDs
for the management interface and one DSUB 15P Telco alarm connector (see
Figure 17).
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 I/O module. However, it cannot use the 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.
