MAINT (PN’s Maintenance Circuit Pack)
Issue 1 June 2005 1501
PN Maintenance Circuit Pack Reset Test (#306)
This test is destructive.
The terminal connection will be dropped and, if the Emergency Transfer switch is in the AUTO
position, Emergency Transfer will be disabled for the duration of the test.
The PN’s Maintenance circuit pack is reset by the active Expansion Interface circuit pack. After
the Expansion Interface circuit pack reports that the PN’s Maintenance circuit pack has reset, a
handshake message is sent to the Maintenance circuit pack. If the Maintenance circuit pack
responds to the handshake, the test passes. If not, it fails. If the test passes, the PN-connected
terminal is brought back up, and Emergency Transfer is restored to its previous state.
2033 ABRT Response to the test was not received within the allowable time period.
1. Retry the command at 1-minute intervals up to 5 times.
FAIL The Sanity Maze of the PN’s Maintenance circuit pack is defective.
1. Replace the PN’s Maintenance circuit pack.
PASS The Sanity Maze is working properly, and the PN’s Maintenance circuit
pack can access the unused register. If recycle carrier (for PN
carriers) does not work, the following problems may still exist:
1. The Carrier Port Power Unit or wiring to the Carrier Port Power Unit
may be defective. See CARR-POW (Carrier Power Supply)
on
page 770.
2. Since this test only tests the PN, there is a very small probability
that the PN’s Maintenance circuit pack cannot access those
registers that deal with PN devices. The Maintenance circuit pack
may need to be replaced.
