Connecting the EPS4000 cord

There are two types of EPS4000 cords available, 1:1 and 1:2. The 1:1 cord can deliver 740 W at 54 V to one switch. The 1:2 cord can deliver 370 W at 54 V to each of two switches from one port on the EPS4000 power supply. Both cords deliver up to 120 W at 12 V. You must use a 1:2 cord if you want an ICX 7250-48P device to share 54-V power with another device. Both 1:1 and 1:2 cords will deliver only 370 W of 54 V power to an ICX 7250-24P device.

Note: The headers on the cords are color coded to help you connect them correctly to the switch and the EPS4000. You must connect the cables tightly using a flat-blade screwdriver for the latching screws. Otherwise, you could experience intermittent power supply failures.

The following figure shows EPS4000 DC power cords

Caution: Do not use the cable to connect two EPS4000 ports.

Note: You can connect either end of the cable first. Hot insertion is supported for cable installation.

Note: The device shown in the diagram may be different from the one you are using. The process to remove the EPS4000 faceplate is the same.

Removing the EPS4000 faceplate on the ICX 7250 device

  1. Faceplate screws
  1. Using a Phillips screwdriver, remove the two screws on the EPS4000 faceplate of the external power receptacle.
  2. Attach the port side connector of the EPS4000 DC cord to the switch.
  3. Attach the EPS4000 side connector of the EPS4000 DC cord to an available DC power port on the back of the EPS4000.
  4. Use a flat-blade screwdriver to attach the latch screw on the DC cord to the EPS4000.
    When the screw is tightened securely, all power supplies to your device will be active.
