Installing a GE Switch

Installing a GE Switch

Installing a CE5855-48T4S2Q-EI (CE5855 for short) switch into a cabinet is a process for installing mounting ears, connecting a PGND cable to the CE5855 switch, sliding the CE5855 switch into the cabinet, and installing a pluggable optical module.

Prerequisites

  • A switch is 1 U in height. The switch installation positions have been planned according to configuration documents.
  • Guide rails and floating nuts have been installed.
  • All required tools have been prepared, containing Phillips screwdrivers, M4 screws, and M6 screws.

Context

CE5855 is responsible for interconnection and communication among nodes and upstream access to the node management and maintenance plane.

Procedure

  1. Wear an ESD wrist strap or ESD gloves.
  2. Insert an optical subcard into the front panel of the CE5855 switch, as shown in Figure 8-45.

  3. Install a PGND cable.

    After the CE5855 switch is installed into the cabinet, there is no adequate room left in the cabinet for installing the PGND cable since the ground screw of the CE5855 switch is on its side. Therefore, it is advisable to install the PGND cable before sliding the CE5855 switch into the cabinet.

    1. Take out an accompanying PGND cable.
    2. Use a Phillips screwdriver to unfasten the M4 screw in the ground terminal of the CE5855 switch.
    3. Use the Phillips screwdriver to secure one end of the PGND cable to the ground terminal of the CE5855 switch, as shown in Figure 8-46.

    When securing the PGND cable to the ground terminal of the CE5855 switch, ensure that the PGND cable is secured in parallel with the cabinet to prevent the PGND cable from being obstructed.

  4. Use M4 screws to secure the mounting ears to both sides of the CE5855 switch, as shown in step 1 of Figure 8-47.
  5. Slide the CE5855 switch along guide rails into the cabinet.
  6. Use M6 screws to secure the mounting ears on both sides of the CE5855 switch to the front mounting bars of the cabinet, as shown in step 3 of Figure 8-47.

    • Secure the two screws in the upper and lower parts of a mounting ear if L-shaped guide rails are used.
    • Secure the screw in the upper part of a mounting ear if L-shaped adjustable guide rails are used.

    The following figure takes the L-shaped guide rails as an example.

  7. Verify that the CE5855 switch is horizontally installed and firmly secured.
  8. Install a pluggable optical module.

    • Wear an ESD wrist strap or ESD gloves to prevent damaging ESD-sensitive optical modules.
    • Do not reversely insert optical modules. If an optical module cannot be inserted into an optical port, do not force it in. In this case, turn it over and try again.
    • Do not remove dust-proof caps from optical connectors before connecting optical fibers to optical modules.
    1. Take out an optical module from its ESD bag and verify that the optical module is intact.
    2. Insert the optical module into an optical port on the subcard until it snaps into place and then raise the handle to lock it up, as shown in Figure 8-48.

      When the locking reed of the optical module makes a "click" sound, the optical module is installed correctly.
