Connecting Power Cables

Connecting Power Cables

Context

To avoid electric shock, do not connect the power cable while the power is on.
  • Power cables must be buried underground or routed indoors and cannot be led into the equipment room aerially.
  • Do not power on a switch before you finish installing the switch and connecting cables.
The power cables required and the cable connection method vary according to the power modules used on the CE8800&7800&6800&5800 series switches:
  • 150 W/350 W/600 W AC power modules:
    • If the external power supply system provides country-specific power outlets, use AC power cables that comply with the local standards.
    • If an AC PDU is used, use C13 straight female to C14 straight male power cables.
  • 350 W/1200 W DC power modules: Use the DC power cables delivered with the power modules to connect the power modules to a DC power distribution box.
  • 600 W/1200 W AC&240 V DC power modules:
    • If the external power supply system provides 220 V AC power input, see the cable requirements for 600 W AC power modules.
    • If the external power supply system provides 240 V DC power input, use C13 straight female to C14 straight male power cables to connect the power modules to a 240 V high-voltage PDU or power distribution box.
  • 600 W/1200 W high-voltage DC power modules: Use 380 V high-voltage DC power cables to connect the power modules to a 380 V high-voltage DC power distribution box or power distribution frame.
NOTE:
  • The AC power cable parameters vary in different countries or regions. The figures in this section are provided only for reference.
  • Power cables are delivered with power modules.
  • If two 1200 W AC&240 V DC power modules are installed on the CE8850-64CQ-EI and 110 V power input is provided to the power modules, you are advised to perform the following operations:
    1. Use an external power source that provides 110 V input with double live wires. In this case, each power module provides 1200 W of rated output power and the power modules work in 1+1 redundancy mode.
    2. If the external power source provides 110 V input with a single live wire, each power module provides 800 W of rated output power. In this case, two power modules must be configured. They power the switch at the same time and do not work in redundancy mode.

Tools and Accessories

  • ESD wrist strap or ESD gloves
  • Phillips screwdriver

Procedure

  1. Wear an ESD wrist strap or ESD gloves. Ensure that the ESD wrist strap is grounded and in close contact with your wrist.
  2. Turn off the power module and the external power supply system for the switch.
  3. Connect the power cable to the power module.
    • For a 150 W/350 W/600 W AC power module, perform the following steps to connect the AC power cable:
      1. Insert the plug of the AC power cable into the power socket on the AC power module.

      2. Lock the AC power cable with the locking strap.

      3. Connect the other end of the AC power cable to the external AC power supply system.
    • For a 350 W DC power module, perform the following steps to connect the DC power cables:
      1. Insert the DC power cable plug to the power socket on the DC power module. Ensure that the positive pole of the plug is connected to the positive socket and the negative pole is connected to the negative socket on the power module.

      2. Connect the cord end terminals at the other end of the power cables to the external DC power supply system. Generally, cord end terminals of the power cables are connected to a DC power distribution box. Connect the positive and negative power cables to the positive and negative terminals in the DC power distribution box correctly.

    • For a 1200 W DC power module, perform the following steps to connect the DC power cables:
      1. Insert the plug of the DC power cable into the power socket on the DC power module, and tighten the red latches on both sides. Ensure that the positive and negative poles of the plug are connected to the positive and negative sockets on the power module, respectively.

      2. Connect the cord end terminals at the other end of the power cables to the external DC power supply system. Generally, cord end terminals of the power cables are connected to a DC power distribution box. Connect the positive and negative power cables to the positive and negative terminals in the DC power distribution box correctly.

    • For a 600 W/1200 W AC&240 V DC power module that uses 240 V high-voltage DC power input, perform the following steps to connect the power cable:
      1. Connect the C13 straight female connector to the power socket on the power module.

      2. Use a velcro strap to bundle the power cable onto the handle of the power module.

      3. Connect the other end of the power cable to the external power supply system.
        • If a 240 V high-voltage DC PDU is used, directly connect the C14 straight male connector to the PDU.
        • If a 240 V high-voltage DC power distribution box is used, make OT or cord end terminals for the cable. Cut the C14 straight male connector off and crimp OT or cord end terminals on the bare wires. Connect the brown wire to a negative terminal on the DC power distribution box, the blue wire to a positive terminal, and the yellow-green wire to a protection ground. If the switch fails to be powered on after you connect the power cable, swap the wires on the positive and negative terminals.
    • For a 600 W/1200 W high-voltage DC power module that uses 380 V high-voltage DC power input, perform the following steps to connect the power cable:
      1. Connect the high-voltage DC straight female connector to the power socket on the power module.

      2. Use a velcro strap to bundle the power cable onto the handle of the power module.

      3. Connect the other end of the power cable to the external power supply system. In most cases, a 380 V high-voltage power distribution box or power distribution frame is used in this scenario. By default, the other end of a 380 V high-voltage DC power cable has bare wires. Crimp OT or cord end terminals on the bare wires, and then connect the brown wire to a positive terminal, the blue wire to a negative terminal, and the yellow-green wire to a protection ground. If the switch fails to be powered on after you connect the power cable, swap the wires on the positive and negative terminals.
