Installing a Cable Manager

Installing a Cable Manager

Cable managers are used for housing cables of the C72 nodes. Each C72 has one cable manager.

Prerequisites

Ensure that the following conditions are met before installing cable managers:

A C72 node has been installed into the cabinet.

Ensure that the following tools and materials are ready:
  • M3 screw
  • Phillips screwdriver
  • Protective gloves
  • Cable manager

Procedure

  1. Arrange cable managers so that both ends of each cable manager are on the same side, as shown in Figure 8-76.

    Figure 8-76  Arranging cable managers

  2. Insert the two sides of the left cable manager to the same side of the ball bearing guide rail and the C72 node.
    1. Insert the upper left of the cable manager into the C72, as shown in step 1 in Figure 8-77.
    2. Insert the lower left of the cable manager into the bracket of the ball bearing guide rail, as shown in step 2 in Figure 8-77.

  3. Use a Phillips screwdriver to fasten M3 screws to secure the left cable manager.
    1. Use a Phillips screwdriver and M3 screws to secure the lower left of the cable manager, as shown in step 1 in Figure 8-78.
    2. Adjust the lower left of the cable manager so that the bottom of the cable manager is against the limiting latch, as shown in step 2 in Figure 8-78.
    3. Use a Phillips screwdriver and M3 screws to secure the upper left of the cable manager, as shown in step 3 in Figure 8-78.

  4. Repeat the previous steps to Install right cable manager.
  5. 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 8-79 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 8-79 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 ground cables) to the front end of the cable manager. Positions 3 in Figure 8-79 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 8-79 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 8-79 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.

  6. Install the spring pins to the left and right cable managers to secure the cable managers.
    1. Pull up the spring pin, as shown in step 1 of Figure 8-80.
    2. Adjust the cable managers to allow the stretchable guide rail of one cable manager to insert into the support of the other cable manager, as shown in step 2 of Figure 8-80.

    When the spring pin aligns with the hole in the support, the spring pin can automatically fall off, and the installation of the spring pin is completed.

  7. Check the cable manager installation.

    Loosen the captive screws on the front panel of a C72 node. Pull the C72 node out of the cabinet or slide the C72 node into the cabinet several times and check whether the cable managers extend correctly.

    • If yes, the cable managers are installed correctly.
    • If no, slightly adjust screws that secure the cable managers.
