Installing Power Modules
The following procedures describe how to install power modules into the chassis. The installation
procedure is the same for both AC or DC modules.
Caution
Never force a power module into the power tray if you feel any resistance! The power modules are keyed
to prevent AC modules from being plugged into a DC power tray or a DC module into an AC power tray.
Forcing a module into the incorrect tray can cause damage to the module and the tray.
Each power module has three status LEDs located on the front left side of its faceplate.
