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.
