EXP-INTF (Expansion Interface Circuit Pack)
Expansion Interface Reset Test (#336)
This test is destructive.
This test is potentially very destructive and requires the EI circuit pack to be
busied out prior to execution of this test.
The Expansion Interface Reset test, which is not part of either the Short or the
Long test sequences test, is executed via the reset board UUCSS command
where UUCSS is the address of the EI circuit pack to be reset.
If the system does not have duplicated Port Network Connectivity, and is a Direct
Connect system, and one of the EI circuit packs must be reset, the action of
busying out the desired EI circuit pack will deny calls to the PN until the EI circuit
pack is released from the busyout state. If the EI circuit pack is part of a PN-to-PN
link, new connections to the PN will be denied. If the EI circuit pack is part of an
PN-to-PN link, calls between the two PNs will be denied.
In a non-duplicated PNC system with a Center Stage Switch, if the EI circuit pack
in the PN is busied out, new service to that PN only will be denied. However, if the
EI circuit pack resides in the PN, new service to every PN will be denied until the
EI circuit pack is released from the busyout state.
If the system does not have duplicated PNC, the reset of any EI is allowed, but it
will result in the resetting of every PN board and loss of service to the PN(s) for a
few minutes.
If the system does have duplicated PNC, and the EI circuit pack to be reset is part
of the active PNC, the system will not allow the busyout and the system technician
will be required to interchange the PNCs via the reset PNC interchange
command. After executing the PNC interchange, it will be possible to busyout and
then reset the original EI circuit pack.
If the PN's Maintenance (MAINT) circuit pack determines that the EI (EXP-INTF)
circuit pack is cycling between sane and insane several times within several
minutes, MAINT may inhibit operation of the EXP-INTF by holding the EI circuit
pack in a reset state. This condition may result in an unsuccessful reset of the EI
circuit pack.
