While the SYSCTL circuit pack is removed,
DO NOT
remove or
replace either combination circuit pack (Main-1 or Main-2).
If an equipped combination circuit pack (Main-1 or Main-2) is
removed from the NE,
DO NOT
replace the SYSCTL circuit
pack.
DO NOT
remove the SYSCTL circuit pack, put it into another
NE, then return it to the original NE (unless another SYSCTL
has been installed in the original NE during the interim).
Procedure
Complete the following steps to replace a SYSCTL circuit pack.
............................................................................................................................................................
1
If necessary, disconnect the LAN and/or serial cables from the

CAUTION
Service disruption hazard
Initializing the SYSCTL in the following steps will momentarily
interrupt service if protection switches are activated.
Ensure that no protection switches are active before initializing
the SYSCTL.
Holding the pack vertically for the wall-mount shelf or horizontally
for the rack-mount shelf, seat the replacement SYSCTL circuit pack
and allow a few minutes for the pack to complete one of the
following initialization cycles.
Result:
The replacement SYSCTL circuit pack will exhibit
unique visible cycles to show that compatible software is
installed, no software is installed (factory-fresh), or
incompatible software is installed.
