To clear SDH/SONET statistics:
• From the Uplink Statistics, select Clear Statistics to clear all collected
SDH/SONET statistic data.
You can also clear all Ethernet and SDH/SONET statistic data by selecting Clear All
Statistics from the Physical Port Statistics menu.
5.2 Detecting
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
.
5.3 Handling
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.
