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 TN464F or later UDS1 circuit packs
administered for 24-channel (1.544-Mbps) operation.
2. If the circuit pack is a TN464F or higher suffix UDS1 circuit pack, then
retry the command.
1951 ABRT The ICSU Status LEDs test cannot be executed because a 120A1 or higher
suffix CSU module or a 401A or higher suffix T1 sync splitter is not
physically installed. If using a 120A1 CSU module or the 401A T1 sync
splitter, physically connect it to the UDS1-BD 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
examine 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, the board should be replaced at the customer’s convenience.
