Cabling the KVM
One function of the management module is to provide keyboard, video, and
mouse (KVM) access to the blade servers in the BladeCenter unit. Keep the
following parameters in mind when using this feature:
v
If you are using a remote session to communicate with the blade servers in
the BladeCenter unit, you do not need to connect a local KVM to the active
management module.
v
Some blade servers do not support KVM access. You need to access these
through the CLI or the serial over LAN (SOL) feature.
v
You cannot use the KVM local interface to directly access the management
module.
Note: If the BladeCenter unit only has one management module, then that is
the active management module. If the BladeCenter unit also has an
optional standby management module, the active management module
will have the green Active LED lit.
See “Management-module input and output connectors” on page 8 for the
location of each connector. Cable the KVM to the active management module,
observing the following guidelines:
v
Connect a keyboard and mouse to the USB ports - Connect a USB
keyboard and USB mouse to USB connectors on the active management
module.
