THE POWER SUPPLY MODULE (CM9700-MPS)
You can add a backup power supply module (CM9700-MPS) to a System 9770 matrix bay to provide redundancy to the bay’s power supply.
INSTALL A BACKUP POWER SUPPLY
1. Open the matrix bay front cover.
2. Remove the blank-off plate from the empty power input slot.
3. Slide the power input module partially into the bay, on the guide rail.
4. Hold the latches parallel to the floor until you reach the edge of the bay’s frame.
5. Adjust the latches to fit them properly onto the top and bottom edges of the bay’s frame.
6. Push the latching levers into the closed position; this seats the power input module firmly into place.
7. Replace the matrix bay front cover.
REMOVE A BACKUP POWER SUPPLY
1. Open the matrix bay front cover.
2. Loosen the screw at the top of the power supply module.
3. Unlatch (pull) the levers at the top and bottom portion of the power supply module.
4. Pull the power supply module towards you (towards the front of the matrix bay) until it is out of the frame.

How to Install or Remove a Power Supply
NOTE: You can “hot swap” a backup power supply module—remove and/or insert a backup power supply—while the system is powered
and running.
