Removing an AC Power Supply from an OCX1100 Switch
The power supplies in OCX1100 switches are hot-removable and hot-insertable
field-replaceable units (FRUs) installed in the rear panel of the switch: You can remove
and replace them without powering off the switch or disrupting switch functions.
Before you remove a power supply from the switch, ensure that you have taken the
necessary precautions to prevent electrostatic discharge (ESD) damage (see
“Prevention
of Electrostatic Discharge Damage” on page 167 ).
Ensure that you have the following parts and tools available to remove a power supply
from the chassis:
•
ESD grounding strap
• Phillips (+) screwdriver
• Antistatic bag or an antistatic mat
•
Replacement power supply or a cover panel for the power supply slot
CAUTION: We recommend that you install either a replacement power supply
or a cover panel in an empty power supply slot to prevent chassis overheating
and dust accumulation.
To remove an AC power supply:
1.
Place the antistatic bag or the antistatic mat on a flat, stable surface.
2.
Attach the ESD grounding strap to your bare wrist, and connect the strap to the ESD
point on the chassis.
NOTE: If only one power supply is installed in your OCX1100 switch, you
need to power off the switch before removing the power supply.
3.
If the AC power source outlet has a power switch, set it to the off ( O ) position.
4.
Gently pull out the male end of the power cord connected to the power source outlet.
5.
Remove the power cord from the power supply faceplate by gently pulling out the
female end of the power cord connected to the power supply faceplate.
