Rebooting
To reboot the CMU, select menu option Reboot. The Reboot Wireless Unit page is
displayed (Figure 199). Select Reboot Wireless Unit. The Reboot Confirmation dialog is
displayed. Select OK. The reboot progress message is displayed. On completion, the unit
restarts.
Use the Diagnostics page to view previous rebbot reasons (see Viewing diagnostics on
page 7-62).

Upgrading software in an operational 1+1 Hot Standby link
In 1+1 Hot Standby links, the forced protection switch minimizes the link down time, since
all units are inactive when upgraded. Protection switching to the newly upgraded units
allows a fallback path should the upgrade have problems.
Upgrading in a different order could make the remote end of the 1+1 Hot Standby link
inaccessible and therefore require an engineer to visit the site to perform the upgrade.
Before upgrading the software, check that no alarms are outstanding for the units to be
upgraded. See Managing alarms on page 7-15.
It is expected that upgrades will normally take place from an initial status of Primary to
Primary, especially for an asymmetric coupler or for a protected antenna when the
inactive unit has a lower capacity.
