Replacing Either Control Panel Power Supply
To replace either control panel power supply proceed as follows:
1. Open the control panel and turn the AC power switch(es) on the left
front of the enclosure to the OFF position. See Figure 4-9.
2. At the rear of the control panel, disconnect the power cord(s) from the
AC source.
WARNING
If the redundant power supply is installed, both power supplies must be
turned off and both power cords must be disconnected.
3. Remove the enclosure covering the power supplies by removing the
screws securing it to the control panel frame. See Figure 4-10.
NOTE:
Removing some control panel internal ribbon cables may make removing
the power supply enclosure easier.
