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.

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.

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.

Note

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).

DC Power Supply in OCX1100 Switches

The DC 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 DC power supplies are shipped with two DC power supplies preinstalled in the rear panel of the switches.

This topic describes the DC 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.

Green

  • Blinking—Power present

  • On steadily—Output on and functioning normally

  • Off—No power

Amber

  • Blinking—Power supply warning events where the power supply continues to operate: high temperature, high power, high current, slow fan.

  • On steadily—Power supply critical event causing a shutdown: power supply failure, overvoltage, overcurrent, overtemperature, fan failure, cord unplugged.
