Removing and installing the LAN module
The LAN module is a hot-swap unit that is installed in 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 system for the two local
area network (Ethernet) connections, as driven from each management module,
and the telco external alarms. This module contains two RJ45 connectors with
LEDs for the management interface and one DSUB 15P male telco alarm
connector. See the “LAN-module indicators and input/output connectors” on page
18 for more information.
