Power

Connect the switch to the applicable power source using the appropriate power cable. An AC power cable is included with each PSU.

When installing AC or DC switches, follow the requirements of the National Electrical Code ANSI/NFPA 70, where applicable.

The switch is powered-up when the power cable is connected between the switch and the power source.

For more information, see Power supplies.

  • CAUTION: Always disconnect the power cable before you service the power supply slots. The switch has multiple power cords. Before servicing, ensure all power cords are disconnected.
  • CAUTION: On the AC switch, use the power supply cable as the main disconnect device. Ensure that the socket-outlet is located/installed near the equipment and is easily accessible.
  • NOTE: Module power is software controlled. You do not see module LEDs when the switch powers up in ONIE.
