EXP-INTF (Expansion Interface Circuit Pack)
When testing EI circuit packs to investigate problems, tests should always be run
on both circuit packs on the associated fiber link, whether the circuit packs are
both EI circuit packs, or one is a SNI circuit pack. This will provide a better
indication of where a problem is located.
When testing of the EI is not possible, (for example, when the PN is down), see
the previous EI Manual Loop-Back procedure.
Expansion Interface Neighbor Query Test (#237)
This test is nondestructive.
The Expansion Interface Neighbor Query test is a request to an EI circuit pack to
determine whether it has established communication with its neighbor EI or SNI
circuit pack.

Error Test
Code Result Description / Recommendation
1033 ABORT The EI circuit pack does not have a fiber link administered to it. There is not
sufficient data to run test.
1. Issue the list fiber-link command to verify that there is no fiber link
2. If there is no fiber administered to this circuit pack, but there should be add
3. Retry the command.
2000 ABORT Response to the test was not received within the allowable time period.
2031 ABORT The attempt to send the message to the EI circuit pack, asking it who it's
neighbor is, was not successful.
2100 ABORT System resources required to run this test are not available. Someone may be
doing something on this Port Network Interface.
2500 ABORT Internal system error
1. Retry the command at 1-minute intervals up to 3 times.
