Non-Hot-Swap Power Supply Replacement
To replace a non-hot-swap power supply, do the following:
1. Grasp the handles located on top of the new power supply. Pivot the handles upward to 90 degrees.
This action puts the handle cams into the correct position to help seat the power supply into its
connector.
2. Carefully insert the new power supply into the bay originally used by the faulty power supply.
3. Lower the power supply release handles, carefully pressing the power supply into the connector. The
spring latch located on the underside of each handle will snap into place, indicating that the power
supply is seated correctly and locked into position.
Note: Improper operation of the spring-activated portion of the power supply handles can result in
the following:
v The retractable spring remains compressed - This situation keeps the handle from locking
the power supply in its seated position. To eliminate this problem, lower the handle into the
locked position, and push the spring-activated handle end toward the locking tab. This
action forces the spring latch to mate with the locking tab in the spring-latch receiver hole.
v
The locking tab receiver is bent - Before lowering the handle to lock the power supply into
the seated position, ensure that the locking tab located on top of the power supply in the
receiver hole is not bent. Before the spring latch will seat onto the locking tab, the locking
tab, if bent, must be straightened.

8. Push the system drawer back into the operating position as described in “Returning the Model 6C4 to
the Operating Position” on page 430.

page 425.
