Installing a PGND Cable and Power Cable for a C72 Node

Installing a PGND Cable and Power Cable for a C72 Node

This section describes how to install a PGND cable and power cable for a C72 node. These cables provide safe grounding and power supply for the C72 node.

Prerequisites

  • Huawei cabinet-accompanying power distribution unit (PDU) or a third party's cabinet-accompanying power distribution device has been prepared.
  • All required tools have been prepared, containing Phillips screwdrivers, cable ties, diagonal pliers, and electrostatic discharge (ESD) gloves or an ESD wrist strap.

Context

For details about power distribution relationship of intra-cabinet components, see Overall Configurations.

Procedure

  1. Wear an ESD wrist strap (or ESD gloves) and insert its ground terminal into the ESD jack on the cabinet.
  2. Connect a PGND cable.
    1. Fetch a yellow-green PGND cable from the packing case of the cabinet.
    2. Remove the screw from a ground point of the C72 using a Phillips screwdriver.
    3. Put the OT terminal of one end of the PGND cable to the ground point, insert the screw, and tighten it, as shown in Figure 9-17.

  3. For details about how to lay out and bind PGND cables, see 6.
  4. Connect power cables.
    1. Determine the mapping relationship between intra-cabinet power cables and the node.
    2. Connect the D-type connector of the delivery-attached power cable into the power socket on the rear panel of the C72, as shown in Figure 9-18.

    3. Fix the power cable to an anti-loosening clip using a cable tie.

      1. Open the pin on the cable tie and slide the cable tie to the position where the AC power cable is connected to the connector, as shown in step 1 of Figure 9-19.
      2. Loosen the AC power cable tie, as shown in step 2 of Figure 9-19.
      3. Close the cable tie to buckle up the joint point of the AC power cable and the connector, as shown in step 3 of Figure 9-19. The AC power cable is fixed to the power socket of the storage device.
      NOTE:

      Before closing the cable tie, adjust it to a position where it buckles up the AC power cable.

  5. Connect the other end of the power cable to the power port of the immediately adjacent PDU and then lock it up, as shown in Figure 9-20.

    To ensure that devices can operate stably, connect power cables on a device supplied by two power modules to separate PDUs.

  6. Route and bind the cables on the cable manager.
    1. Bind all the signal cables on the right (including SFP+ high-speed cables and network cables). Positions 1 in Figure 9-21 are where the cables are bound to enter the cable manager.
    2. Bind all the signal cables on the right with the power cables to the handle of the fan module. Positions 2 in Figure 9-21 are where the cables are bound to enter the cable manager.
    3. Bind all the cables on the right (including signal cables, power cables, and PGND cables) to the front end of the cable manager. Positions 3 in Figure 9-21 are where the cables are bound to enter the cable manager.
    4. Route and bind cables along the trough of the cable manager. Positions 4 in Figure 9-21 are where the cables are bound to enter the cable manager.
    5. Route and bind cables along the trough of the cable manager. Positions 5 in Figure 9-21 are where the cables are bound to get out of the cable manager.

    Repeat the previous steps to route and bind cables onto the left cable manager.

    NOTE:

    Evenly divide the cables connected to the storage device into two parts. Place the left part of cables into the troughs of the left cable manager, and the right part in the troughs of the right cable manager.
