Expansion Interface Link Switch Command
This action is potentially destructive.
The Expansion Interface switch command enables system technician to choose
which set of Expansion Interface Links should be the Active link when duplicate
Expansion Interface Links are available.
The command line entry is set expansion-link PCSS, where PCSS is the
Expansion Interface address of
either Expansion Interface circuit pack on the
FAIL
(cont’d.)
PROCEDURE C
Use Procedure C if the Expansion Interface circuit pack to be tested
is part of any link from EPN to EPN.
1. Test the Packet Control circuit pack. If the Packet Control circuit
pack fails any tests, refer to the PKT-CTRL Maintenance
documentation for recommended maintenance procedures.
2. If all Packet Control circuit pack tests pass, the failure may be in
the Expansion Interface circuit packs of the EPN to EPN link or on
the EPN Packet Bus.
3. Issue the test board PCSS long command on both EPN to EPN
Expansion Interface circuit packs and follow the procedures for
Test #242.
PASS The data packet was received correctly.
1. Refer to other Expansion Interface circuit pack tests if the
Expansion link is not functioning correctly.
0NO
BOARD
No board was detected by the test.
1. Check the error log for wrong board (error 125) or no board (error
131). Resolve either of these issues, if applicable.
2. Check that the board is properly translated and inserted. If so,
check for hyperactivity (error 1538). If hyperactive, use the reset
board PCSS command.
3. Run the test again. If it fails, the ID chip on board may be bad.
Replace the board and retest.
