Cabling the KVM and LAN modules
The KVM (keyboard, video, mouse) module provides the electrical and
mechanical interface to the BladeCenter T unit for a local keyboard, video
monitor, and mouse.
The LAN module provides the electrical and mechanical interface to the
BladeCenter T unit for the two local area network (Ethernet) connections,
driven from each BladeCenter T management module, and the telco external
alarms. There is a separate dedicated LAN connector for each management
module, and both must be connected to the active management network to
have complete management-module redundancy. Both the KVM and LAN
modules are at the rear of the BladeCenter T unit.
The BladeCenter T management module controls the KVM module and the
LAN module. When two management modules are installed in the
BladeCenter T unit, only one management module is active; the second
management module, if present, provides redundancy. The active management
module is the primary module; the redundant management module is the
secondary module. If the primary management module fails or if you request a
changeover through the Web interface, the secondary management module
becomes active and primary and takes over the control of the KVM and LAN
modules.
