AC Power Supply in OCX1100 Switches
The AC power supply in OCX1100 switches is a hot-insertable and hot-removable
field-replaceable unit (FRU): You can install it without powering off the switch or
disrupting switch functions.
All OCX1100-48SX switches that are powered by AC power supplies are shipped with
two AC power supplies preinstalled in the rear panel of the switches.
This topic describes the AC power supplies.
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.
