Connecting the RPS Cable and AC Power Cord to an STK-RPS-1005PS

About this task

The STK-RPS-1005PS RPS (redundant power supply) is connected to the switch using the supplied RPS cable. Use RPS Cable and AC Power Cord Connections for the STK-RPS-1005PS to guide you through the steps.

Caution

Caution

Observe all ESD precautions when handling sensitive electronic equipment.
Note

Note

The switch should not be powered on during installation of the power supply. This is not a hot-swap procedure. Follow the steps in the order specified.

RPS Cable and AC Power Cord Connections for the STK-RPS-1005PS
1 = STK-RPS-1005PS power supply 7 = AC power outlet with ground connection for switch
2 = Switch 8 = Redundant power supply connector on power supply
3 = RPS cable 9 = Redundant power supply connector on switch
4 = RPS AC power cord 10 = AC connector on power supply
5 = Switch AC power cord 11 = AC connector on switch
6 = AC power outlet with ground connection for power supply

Procedure

  1. Connect one end of the RPS cable (3) to the RPS connector at the rear of the power supply (8).
  2. Connect the other end of the RPS cable (3) to the RPS connector on the switch (9).
    Note

    Note

    AC power cords and outlets vary depending on country. See Selecting Power Supply Cords for more information.
  3. Connect the AC power cord (4) to the AC input power connector on the power supply (10).
  4. Plug the AC power cord (4) into the main AC power outlet (6).
  5. Connect the second AC power cord (5) to the AC input power connector on the switch (11).
  6. Plug the AC power cord (5) into the main AC power outlet (7), preferably on a different circuit for better redundancy.

Results

The AC OK and DC OK LEDs on the front of the power supply turn green to indicate that the connection was successful and the power supply is operating properly.

If the LEDs do not light properly, follow these steps to troubleshoot:

  • Check the AC power cord connection at the AC power source and make sure the power source is within specification.
  • Check the AC power connection to the power supply.
  • Swap the AC power cord with one that is known to work properly.
