OCX1100 Power System
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.
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)
andAIR OUT (AFO)
) in the same chassis.Power supplies and fan modules with different airflow labels (
AIR IN (AFI)
andAIR OUT (AFO)
) in the same chassis.

AC Power Supply Airflow
Each power supply has its own fan and is cooled by its own internal cooling system.
Each power supply has the label AIR OUT (AFO)
or AIR IN (AFI)
on the faceplate of the power
supply that indicates the direction of airflow in the power supply.
Table 2 lists the AC power supply models and the direction of airflow in them.

AC Power Cord Specifications for an OCX1100 Switch
Each AC power supply has a single AC appliance inlet that requires a dedicated AC power feed. A detachable AC power cord is supplied with each AC power supply. The 460 W AC power supplies are shipped with AC power cords with the C13 coupler type as described by International Electrotechnical Commission (IEC) standard 60320. The plug end of the power cord fits into the power source outlet that is standard for your geographical location.
In North America, AC power cords must not exceed 14.75 ft (4.5 m) in length, to comply with National Electrical Code (NEC) Sections 400-8 (NFPA 75, 5-2.2) and 210-52 and Canadian Electrical Code (CEC) Section 4-010(3).
Table 4 lists the AC power cords specifications provided for different power supplies for each country or region.
