ABRT Internal system error
1. Retry the command at 1-minute intervals up to 5 times.
1005 ABRT The ICSU Status LEDs test cannot be executed for the current configuration.
The test applies only to TN767E or later DS1 circuit packs administered for
24-channel (1.544-Mbps) operation.
2. If the circuit pack is a TN767E (or higher-suffixed) DS1 circuit pack,
then retry the command.
1951 ABRT The ICSU Status LEDs test cannot be executed because a 120A1 (or
higher-suffixed) CSU module or a 401A (or higher-suffixed) T1 sync splitter
is not physically installed. If using a 120A1 CSU module/T1 sync splitter,
physically connect it to the TN767E board on the back of the port carrier.
Otherwise, ignore this abort.
2100 ABRT Could not allocate the necessary system resources to run this test.
1. Retry the command at 1-minute intervals up to 5 times.
2500 ABRT Internal system error.
1. Retry the command.
PASS The ICSU Status LEDs test executed successfully. A PASS result, however,
does not necessarily mean that the status LEDs behaved properly. It only
means that the software successfully attempted to light the status LEDs.
This is a visual test. The service technician must visually exam the behavior
of the LEDs while the test is running. The LEDs are functioning properly if
the four status LEDs are lit red for 5 seconds, then lit green for 5 seconds,
then lit yellow for 5 seconds. If the LEDs behave differently, escalate this
problem.
