Network Switch Module Features

Each system can accommodate up to two network switch modules. The network switch modules provide information about network activity and link status and

a system fault indicator (see Figure1-6). The switch also provides an external RJ11 connection to a serial null modem cable used for switch setup and

configuration. The RJ11 is not used during normal system operation. Table1-4 provides details about the operation of the indicators.

System Management Module Features

The system management module provides:

l Keyboard/mouse/video access to each server module

l Serial and Ethernet management ports

l An analog rack interface port to attach to an optional external KVM over IP switch

l Status indicators for the system management module and for the link to the system's onboard network switch module.

In addition, a system status connector allows you to attach the system status cable so that you can monitor system status after the system is mounted in a

rack (see Figure1-7). Table1-5 provides information about the status indicators.
