6.2 Detecting Errors
Power-Up Self-Test
ASMi-52 performs a hardware self-test upon power-up. The self-test sequence
checks the critical circuit functions of the modem.
The results of the hardware self-test for the local or remote ASMi-52 are displayed
in the System Status and Physical Status Port screens (see Chapter 4).
Front Panel LEDs
The status of ASMi-52 is indicated by the ALM, TST and SYNC LED indicators
located on the front panel. For the description of LEDs and their functions, refer to
Chapter 3.
6.3 Handling Alarms
ASMi-52 detects fault conditions and initiates alarms to alert the user. ASMi-52
supports the following alarm types:
• System alarms, relating to the ASMi-52 chassis
• Port alarms, relating to a specific interface (SHDSL or DTE)
• Information messages (warnings)
• Events that trigger alarm activation.
ASMi-52 maintains two separate displays for the system and port alarms. In
addition, the modem supports a local log file, holding up to 100 alarms.
An alarm or warning simultaneously activates the alarms display and generates a
log file, and the ALM LED turns on to indicate the condition. When the fault
condition that caused the alarm is cleared, the alarm is removed from the alarm
screen, but remains in the log file, enabling you to view the alarm history. Events
are generated into the log file.
