Additional Tests for Replaced DATA-CHL,
PKT-CTRL, and PROCR Circuit Packs
PKT-CTRL, and PROCR Circuit Packs
After
all
affected circuit packs have been replaced, if the replaced circuit packs
include the TN777B Network Control circuit pack(s), the TN778 Packet Control
circuit pack(s), or the Processor circuit pack(s), additional testing is required to
ensure that the new circuit packs are healthy. This testing must be done on these
circuit packs when they are located in the Active SPE. Issue the
circuit pack(s), or the Processor circuit pack(s), additional testing is required to
ensure that the new circuit packs are healthy. This testing must be done on these
circuit packs when they are located in the Active SPE. Issue the
status system
command to determine which SPE is currently the Active SPE and determine the
SPE, Active or Standby, in which each replaced Network Control, Packet Control,
and/or Processor circuit pack resides.
SPE, Active or Standby, in which each replaced Network Control, Packet Control,
and/or Processor circuit pack resides.
If any of the replaced circuit packs are located in the Active SPE, test it by
issuing the
issuing the
test network-control [a | b]
,
test packet-control [a | b]
, or
test
processor [a | b]
command, as appropriate. If any tests fail or abort, refer to the
SW-CTL (Switch Control), DATA-CHL (Network Control Data Channel),
PKT-CTRL (Packet Control Circuit Pack, DATA-BD (Network Control Circuit
Pack), or PROCR, and PR-MAINT (Maintenance/Tape Processor) Maintenance
documentation in
PKT-CTRL (Packet Control Circuit Pack, DATA-BD (Network Control Circuit
Pack), or PROCR, and PR-MAINT (Maintenance/Tape Processor) Maintenance
documentation in
, as
appropriate.
If any of these circuit packs are located in the Standby SPE, force the Standby
SPE to become the Active SPE as described in "Upgrading SPE Circuit Packs."
However, before the Standby SPE is made to become the Active SPE, the
replaced circuit pack should first be tested while on the Standby SPE. Then, test
these circuit packs (that are now located in the Active SPE) by issuing the
SPE to become the Active SPE as described in "Upgrading SPE Circuit Packs."
However, before the Standby SPE is made to become the Active SPE, the
replaced circuit pack should first be tested while on the Standby SPE. Then, test
these circuit packs (that are now located in the Active SPE) by issuing the
test

,
test packet-control [a | b]

WARNING:
Before leaving the system, verify that the SPE Select Switches have been
returned to their proper position. The switches should be in the AUTO
position and the SPE Select Switch LEDs should be off on both the TN772
Duplication Interface circuit packs.
