To install the replacement power supply in the switch (see Figure 62 on page 181 ):
a. If you have not already done so, attach the ESD grounding strap to your bare wrist,
and connect the strap to the ESD point on the lower right front of the chassis—or
hold the component in its antistatic bag in one hand and touch the exposed, bare
metal of the switch with the other hand.
b. Taking care not to touch power supply pins, leads, or solder connections, remove
the replacement power supply from its antistatic bag.
c. Using both hands, place the replacement power supply in the empty power supply
slot in the switch and slide it in until you hear a distinct click sound, indicating that
the power supply is fully seated in the chassis.
