Additional Tests for Replaced DATA-CHL,
PKT-CTRL, and PROCR Circuit Packs
After all affected circuit packs have been replaced, if the replaced circuit packs
include the Network Control circuit pack(s), the 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 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.
If any of the replaced circuit packs are located in the Active SPE, test it by 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
Chapter 10, ‘‘Maintenance Object Repair Procedures’’ , 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 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), DATA-BD (Network Control
Circuit Pack), PKT-CTRL (Packet Control Circuit Pack), or PROCR, and
PR-MAINT (Maintenance/Tape Processor) Maintenance documentation in
Chapter 10, ‘‘Maintenance Object Repair Procedures’’ , as appropriate.

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.
See the following flowchart, Figure 6-1 on page 6-31 , Figure 6-2 on page 6-32 and
Figure 6-3 on page 6-33 , for the procedure for installing or replacing Standby SPE
Circuit Packs in Duplication Option System.
