NIC Indicator Codes
Each NIC on the back panel has an indicator that provides information on network activity and link status (see Figure3-6). Table3-7 lists the NIC indicator
codes on the back panel.
The front panel has a link indicator for each NIC (see Figure3-2). Each indicator signifies whether the corresponding NIC is connected to a valid link partner on
the network.

LCD Status Messages
The system's bezel indictor can signify when the system is operating correctly or when the system needs attention (see Figure3-1). When the bezel indicator
signifies an error condition, remove the bezel to see further information provided by the status LCD.
The LCD can display two lines of alphanumeric characters. The display codes are presented in two color combinations:
l White characters on a blue background — Information only; no action is required.
l Amber characters on a black background — The system needs attention.
Table3-9 lists the LCD status messages that can occur and the probable cause for each message. The LCD messages refer to events recorded in the SEL. For
information on the SEL and configuring system management settings, see the systems management software documentation.
