LCD Screens

The two LCD screens below the PC media card slots display alphanumeric information about the status of the of the PRE module.

PRE LED Indicators and Buttons

LEDs on the faceplate of the PRE provide a visual indication of the status of PRE operation (see Figure 1-10). The LEDs are separated into three categories: alarms, status, and failure.

•ALARM—Alarm relay contacts on the Cisco uBR10012 router connect the router to a site alarm maintenance system. This allows critical, major, and minor alarms generated by the

Cisco uBR10012 router to be displayed on the PRE faceplate and also translated to external visual or audible alarms connected to the system. See the “Connecting Alarm Indicators” section on page 3-31for more information about alarm connections. Pressing the alarm cutoff (ACO) button on the (primary) PRE during an alarm condition shuts off the external alarm, but does not deactivate the alarm LEDs on the PRE faceplate. Alarm LEDs on the faceplate are deactivated only after the condition that caused the alarm is corrected.

•STATUS—Indicates the status of the PRE.

•FAIL—Indicates that a major failure has disabled the PRE.

Table 1-5describes the LEDs and switch on the PRE.
