Connecting Power Cables

Connecting Power Cables

Follow the operation guide to connect power cables from the power module of the USG6515E, USG6525E, USG6550E, USG6555E, USG6560E, USG6565E, USG6575E-B, USG6580E, USG6585E, USG6605E-B, USG6610E, USG6615E, USG6620E, USG6625E, USG6630E, USG6635E, USG6650E, USG6655E to the output of the power supply device.

Connecting AC Power Cables

By default, the USG6515E, USG6525E, USG6550E, USG6555E, USG6560E, USG6565E, USG6575E-B, USG6580E, USG6585E, USG6605E-B, USG6610E, USG6615E, USG6620E, USG6625E comes with one AC power module. However, two AC power modules are supported. The USG6630E, USG6635E, USG6650E, USG6655E comes with two AC power module. Each AC power module requires an AC power cable. When two AC power modules are used, connect power cables to both AC power modules.

Context

Before connecting the power cables, ensure that the AC power supply in the equipment room meets the input requirements of the USG.

Do not connect or disconnect the power cables when the USG is powered on.

Procedure

  1. Ensure that the PGND cable is adequately grounded.
  2. Connect AC power cables to AC power modules.

    When two power modules are used, connect them to different power sources to improve availability.

    1. Plug one end of the C13 power cable to the power socket of the USG power module and adjust the cable-retention clip to an appropriate position.
    2. Bundle the AC power cable using a cable-retention clip and adjust the cable-retention clip to fasten the AC power cable.
    3. Plug the other end of the power cable to the AC power socket or the output of the AC power supply device.

      Figure 5-34 Connecting AC power cables (USG6515E, USG6525E, USG6550E, USG6555E, USG6560E, USG6565E, USG6575E-B, USG6580E, USG6585E, USG6605E-B, USG6610E, USG6615E, USG6620E, USG6625E)

Follow-up Procedure

Verify the following after the connection is complete:

  • The power cable is firmly connected to the power supply socket.
  • If multiple USGs are deployed, the power cables of each USG are correctly labeled for distinction.

Connecting DC Power Cables

The USG6630E, USG6635E come with two DC power module. Each DC power module requires an NEG power cable and an RTN power cable. Connect power cables to both DC power modules.

Context

Before connecting power cables, ensure that the DC power supply in the equipment room meets the input requirements of the USG.

Do not connect or disconnect the power cables when the USG is powered on.

Procedure

  1. Ensure that the PGND cable is adequately grounded.
  2. Connect power cables for the two DC power modules one after the other.

    • Note the labels on the DC power cables to avoid misoperations.
    • To improve availability, connect two power modules to different power sources.

    1. Plug the connector end of the DC power cable to the DC power module.
    2. Connect the other end of the DC power cable to the output of the power supply device in the equipment room.

      Figure 5-36 Connecting DC power cables

Follow-up Procedure

Verify the following after the connection is complete:

  • The power cables are correctly and firmly connected to the power supply device.
  • If multiple USGs are deployed, the power cables of each USG are correctly labeled for distinction.
