5.2Detecting Errors

Power-Up Self-Test

RIC-155 performs a hardware self-test upon turn-on. The self-test sequence checks the critical circuit functions of RIC-155. If RIC-155 fails the self-test, the Self test failure alarm is stored in the alarm buffer (see Table 5-2).

Front Panel LEDs

The status of RIC-155 is indicated by the ALM LED indicator located on the front panel. For the description of the ALM LED and its functions, refer to Chapter 3.

5.3Handling Alarms

RIC-155 detects fault conditions and initiates alarms to alert the user. RIC-155 supports three alarm types:

•System alarms

•Information messages (warnings)

•Events.

RIC-155 maintains a separate display for all active system alarms. In addition,

RIC-155 supports log file, holding up to 200 alarm entries.
