What Types of Power Cables Do CloudEngine 12800 and 12800E Series Switches Support?

The figures provided here are for reference only and may differ from the actually delivered cables.

AC Power Cable

The AC power cables applicable to CloudEngine 12800 and 12800E series switches depend on the type of power sockets used in your equipment room. Two types of AC power cables are available to suit different power sockets: PDU power cable and country-specific power cable.

  • PDU power cables are delivered with a power distribution unit (PDU) with C20 straight sockets. A PDU power cable has a C19 straight female connector at one end and a C20 straight male connector at the other end, as shown in Figure 22-59.
  • Country-specific power cables are delivered in compliance with standards of the destination country or region. For example, AC power cables used in China have PI angle male connectors, as shown in Figure 22-60.

If PDUs with C20 straight sockets are available in a cabinet, use PDU power cables complying with local standards.

If there is no PDU with C20 straight sockets in a cabinet, use power cables specific to the country or region where the switch is used.

Connection

An AC power cable transmits AC power to a chassis and allows maximum current of 16 A. It is connected in the following way:

  • The C19 straight female connector is connected to a socket on the power distribution unit at the rear of the CloudEngine 12800 and 12800E chassis.
  • The country-specific connector or C20 straight male connector at the other end is connected to an external power outlet.

DC Power Cable

DC power cables for CloudEngine 12800 and 12800E series switches include a -48 V power cable and an RTN ground cable. DC power cables with the following cross-sectional areas are available: 16 mm2, 25 mm2, and 35 mm2.

You need to cut the delivered DC power cables into appropriate lengths according to actual situations in your site and make DC power cables onsite.

Figure 22-61 shows the appearance of a DC power cable.

Figure 22-62 shows the structure of a DC power cable.

Connection

A DC power cable transmits DC power to a chassis and allows maximum current of 62 A. It is connected in the following way:

  • The JG2 M6 terminal is connected to power terminals on the power distribution unit at the rear of CE12800&CE12800E chassis.
  • The OT M8 terminal is connected to an external power source.

High-Voltage DC PDU Power Cable

Figure 22-63 shows a high-voltage DC PDU power cable.

Figure 22-63 High-voltage DC PDU power cable and high-voltage DC PDU

Connection

A high-voltage DC PDU power cable transmits 240 V high-voltage DC power to a chassis and allows maximum current of 18.5 A. It is connected in the following way:

  • The C19 straight female connector is connected to a socket on the power distribution unit at the rear of the CloudEngine 12800 chassis.
  • The C20 straight male connector is connected as follows:
    • If a high-voltage DC PDU is used, directly connect the C20 straight male connector to a socket on the high-voltage DC PDU.
    • If a high-voltage DC power distribution box is used, make OT terminals for the cable. Cut the C20 straight male connector off to expose the wires in the cable. 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 protection ground.
