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 Expansion Interface 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 Expansion Interface circuit packs must be reset,
the action of busying out the desired Expansion Interface circuit pack will deny
calls to the EPN until the Expansion Interface circuit pack is released from the
busyout state. If the Expansion Interface circuit pack is part of a PPN to EPN link,
new connections to the EPN will be denied. If the Expansion Interface circuit
pack is part of an EPN to EPN link, calls between the two EPN s will be denied.
In a non-duplicated PNC system with a Center Stage Switch, if the Expansion
Interface circuit pack in the EPN is busied out, new service to that EPN only will
be denied. However, if the Expansion Interface circuit pack is located in the PPN,
new service to all EPN s will be denied until the Expansion Interface 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 all EPN boards and loss of service to the EPN (s) for a
few minutes.
If the system does have duplicated PNC, and the Expansion Interface 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 Expansion Interface circuit pack.
If the EPN Maintenance (MAINT) circuit pack determines that the Expansion
Interface (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 Expansion Interface circuit pack in a reset state. This condition may
result in an unsuccessful reset of the Expansion Interface circuit pack.
If the reset command returns “EPN is unavailable,” execute the following steps:
1. Use the
change circuit-pack P
(port network number of the EPN)
command.
2. For the Expansion Interface circuit pack you wish to reset, add an entry to
the Circuit Pack form for the TN570 Expansion Interface circuit pack. Be
sure to enter the appropriate carrier and slot.
3. Enter the form.
4. Issue the busyout board UUCSS command.
5. Repeat the reset board command
