Step 3 Hold the MDU front panel by one hand, and push out the MDU from the fastener
on the front panel by the other hand.
Step 4 Install the new MDU in the bracket, and secure it using screws.
Step 5 Connect the communications cables to the MDU.
Step 6 After the MDU is replaced, the new MDU automatically checks whether its
congurations are consistent with the rack conguration during startup. If an
inconsistency is found, the MDU displays a synchronization dialog box, as shown
in Figure 8-20.

congurations. The MDU restarts.
2. If you click Cancel (not recommended), the congurations will not be
synchronized, and the MDU displays the same dialog box after the next
startup.
