out the desired Expansion Interfac e circuit pac k WILL DISRUPT SERVICE TO
THE EPN until the circuit pack is released from the busyout s tate. If the circuit
pack is part of a PPN to EPN link, the EPN WILL BE WITHOUT SERVICE. If the
circ uit p ack is pa rt of a n EPN to EPN link C ALLS BETWEEN THE TWO EPNs WI LL
BE DENIED.
If the system has working duplic ate EI links, and the EI circuit pack to b e reset is
part of the active EI link, the system d oes not allow the busyout and instruc ts
system technician to switc h EI links via the set expansion-link PCSS command
where PCSS is the address of either Standby Expansion Interface c ircuit pack on
the Standby link. After executing the EI link switch, it is possible to b usyout and
then reset the original EI circuit pac k.
However, if the EPN Maintenance (MAINT) circuit pac k determines that the
Expan sion I nter face (EXP-INTF) circ uit p ack is cy clin g be tween sane and i nsane
several times within several minutes, MAINT may inhibit op eration 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.
If the reset command returns with EPN is unavailable, execute the foll owing:
1. Use the change circuit-pack P command, where P is the port network
number of the EPN.
2. For the EI circuit pack you wish to reset, ad d an entry to the Circuit Pack
form for the TN776 Expansion Interface circuit pack. Be sure to enter the
appropriate carr ier and slot (that is, A01 or B02).
3. Repeat the reset board command.

Error
Code Test
Result Description/ Recommendation
ABORT Internal system error.
1. Retry the command at 1-minute intervals a maximum of 3 times.
4 ABORT Could not reset EPN Expansion Interface circuit pack over optical fiber since
PPN Expansion Interface circui t pack on opp osite end of fiber is not inse rted.
1. Insert opposite EI circuit pack and p erform reset again.
1015 ABORT The system does not allow this test to be run because the EI circuit pack has
not been busied out.
1. Busyout the Expansion Interface circuit pack. Repeat the reset board
PCSS command.
