Procedure
Step 1 Confirm where the SPCs are to be installed.
Before expanding SPC capacity, first confirm where the SPCs are to be installed, including
the cabinets, chassis, and slots. Ensure that the SPCs are installed in the same slot on the
active and standby FWs.
Step 2 Check whether the connectors of the SPCs to be installed are damaged.
Step 3 Optional: If two FWs work in load balancing mode, switch the operating mode to the active/
standby mode. To switch the operating mode, run the hrp switch active command on either
FW.
If the two FWs work in active/standby mode, skip this step.
HRP_M<sysname> system-view
HRP_M[sysname] hrp switch active
The FW on which the hrp switch active command is executed has its VGMP group priority
increased by 1 to be higher than that of the other FW and therefore becomes the active FW.
The other FW become the standby FW. Services on the standby FW are switched to the active
FW. Service switchover takes a few moments. To ensure service continuity, run the hrp
switch active command and wait one minute before performing subsequent operations.
Step 4 Run the undo hrp track spu enable command on the standby FW to disable the VGMP
group from monitoring the SPU.
HRP_S<sysname> system-view
HRP_S[sysname] undo hrp track spu enable
After the SPC is inserted into the standby FW, its VGMP group priority increases and
becomes higher than that of the active FW, triggering active/standby switchover. In addition,
after the SPU is inserted, session tables on the standby FW are deleted. If active/standby
switchover occurs at this time, service traffic is discarded by the standby FW due to failure to
match session tables after being diverted to the standby FW. Therefore, before the SPC is
inserted into the standby FW, run the undo hrp track spu enable command on the standby
FW to disable the VGMP group from monitoring the SPU. In this way, after the SPC is
inserted into the standby FW, its VGMP group priority does not increase, active/standby
switchover is not triggered, and service traffic is still forwarded by the active FW.
Step 5 Insert the SPC into the SPU motherboard of the standby FW.

NOTE
Take out the new SPC from the ESD bag.
NOTICE
– Pull out the SPU slowly and smoothly so that it does not bump into neighboring
boards and cause a malfunction.
– When inserting an SPC, do not touch the parts on it to avoid damaging the SPC.
