Capacitor Books and Blanks

The following safety notice applies to power-related field replaceable units.

Do not attempt to open the covers of the power supply. Power supplies are not serviceable and

are to be replaced as a unit.

1. Turn off power as described in "Powering Off and Powering On the System" on page 854.

2. If you have not already done so, open the rear door of the rack unit.

3. Locate the capacitor book or blank to be removed.

4. Loosen the upper and lower fasteners, using the torque tool (part number 6422789), alternating

between the fasteners until the unit can slide out of the slot.

5. Grasp both sides of the capacitor book or blank, and pull it out of the drawer.

1. Carefully slide the capacitor book into the slot as far as possible (the back edge of the top of the

capacitor book is about .25 inch from the cage bracket).

Note: Do not force the capacitor book against the backplane, as this may damage the connector.

2. Hold the upper part of the capacitor book against the backplane, and use the torque tool to engage the

upper fastener about two turns into the cage bracket.

3. Repeat the previous step for the lower fastener.

4. Alternate tightening the upper and lower fasteners until both are fully torqued in.

5. Check torque on both fasteners.

6. If any cables were removed during the removal procedure, plug all cables into their correct locations.

7. Turn on the power as described in "Powering the System On" on page 857.
