Installing a DC Power Supply in an OCX1100 Switch
The DC power supply in OCX1100 switches is a hot-removable and hot-insertable
field-replaceable unit (FRU) installed in the rear panel of the switch: You can remove
and replace it without powering off the switch or disrupting switch functions.
CAUTION: Do not install:
•
AC and DC power supplies in the same chassis.
• AC power supplies in DC switch models or DC power supplies in AC switch
models.
•
Power supplies with different airflow labels (
AIR IN (AFI)
and
AIR OUT
(AFO)
) in the same chassis.
•
Power supplies and fan modules with different airflow labels (
AIR IN (AFI)
and
AIR OUT (AFO)
) in the same chassis.
Before you install a DC power supply in the switch:
•
Ensure you understand how 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 install a DC power supply
in the switch chassis:
• ESD grounding strap
•
Phillips (+) screwdriver
NOTE: Each power supply must be connected to a dedicated power source
outlet.
To install a DC power supply in the switch:
1.
Ensure that you have the correct power supply. The label AIR IN (AFI) or AIR OUT
(AFO) on the power supply must match the label AIR IN (AFI) or AIR OUT (AFO) on
the installed fan module.
2.
