Replacing an MPU
Prerequisites
1. If the router is configured with only one MPU, make sure all power sources to the router are turned
off before replacing the MPU.
2. If the router is configured with two MPUs, make sure both MPUs operate correctly before replacing
any MPU.
{
To replace the active MPU, H3C recommends that you execute the slave switchover command
in the system view of the active MPU to trigger an active and standby switchover. For more
information about the slave switchover command, see H3C SR6600/SR6600-X Routers High
Availability Command Reference.

To replace the standby MPU, you can remove it immediately.
