Avaya 03-300430 User Manual

This test requests the Packet Interface to execute its two private loop-around tests: Level-2 
Loop Around, and Broadcast Path Loop Around. These tests verify the health of the circuit 
pack’s packet-bus interface, as well as the translation RAM, inward and outward bound data 
paths, parity indications and CRC calculations.

●

Level-2 (LAPD) Link Loop Around

LAPD is a link-level protocol that is used for all system links. This test verifies the health of 
the processing of these links.

FAIL

The Flash memory checksum test failed. The circuit pack may still be 
operational, but will fail if a reset is executed.

1. This may be the result of old firmware not supporting new software 

operation. Verify the IPSI circuit pack’s firmware vintage and download 
the new firmware if appropriate.

2. The firmware image on the IPSI circuit pack may have been corrupted. 

Download the firmware image.

3. Retry the command.

4. If the same error occurs:

a. If this is a standard- or duplex-reliability system, replace the circuit 

pack at a time that would cause the least disruption of service. The 
circuit pack is still functional but should be replaced since it may not 
operate after a system reboot and it will enter a fatal fault state if it is 
reset for other reasons.

b. If the Packet Interface module is on the standby IPSI (

: and 

this is a high- or critical-reliability system), replace that circuit pack.

c. If the Packet Interface module is on the active IPSI (

: and 

this is a high- or critical-reliability system), use set 
ipserver-interface to perform a planned IPSI interchange.

FAIL

The Boot PROM memory Checksum test and the Flash memory checksum 

test have both failed. Follow the steps listed for FAIL Error Codes 1 and 2.

PASS

The circuit pack’s firmware is in a proper state. If problems are still reported 

on the circuit pack, check for errors on the Private Loop-around test (#885) 

and Maintenance Loop-Around test (#886).
