Replacement

To replace a redundant power supply:

1. Remove the replacement power supply from its shipping container.

2. Inspect the rear of the power supply for bent or broken connector pins that

may have been damaged during shipping. If any pins are damaged, obtain a

new power supply.

3. Position the power supply in the rear of the switch chassis as shown in part

(B) of Figure 56. Ensure the finger handles are disengaged and rotated 90

degrees outward.

a. While supporting the power supply with one hand, insert it into the switch

chassis.

b. Firmly push the power supply into the chassis. Rotate the finger handles

90 degrees inward to seat the power supply and engage the connector

pins. Ensure the faceplate is flush with the chassis cutout.

4. Connect the AC power cord to the power supply and to a facility power

source.

5. Wait several seconds, then inspect the power supply to ensure the amber LED

is extinguished. If the LED is illuminated, go to “MAP 0000: Start MAP” on

page 32 to isolate the problem.
