        Replacing the Fan-Tray Assembly in the Cisco ME 2600X Shelf

        Purpose This procedure describes how to replace the fan-tray assembly in the Cisco ME 2600X shelf.
        Tools/Equipment Number-2 Phillips Dynamometric screwdriver
        Prerequisite Procedures

        • Installing the Cisco ME 2600X Shelf

        • Connect the chassis to the office ground. For detailed instructions on how to ground the chassis, see the Electrostatic Discharge and Grounding Guide for Cisco CPT and Cisco ONS Platforms.
        Required/As Needed Required
        Onsite/Remote Onsite
        Security Level None

        Caution

        Do not operate the shelf without an air filter.


        Note

        The estimated time for a skilled technician to replace an equipment fan or fan tray is 2 minutes.


        Note

        The fan or the cooling unit can be replaced without service interruption.


        Caution

        Do not force a fan-tray module into place. Doing so can damage either the connectors on the fan tray or the connectors on the back panel of the shelf assembly, or both.


        Note

        Error messages appear on the fan-tray LED, when the fan-tray module is removed from the shelf or when one fan is not working.

        Procedure
          Step 1   Loosen the screw on the fan-tray assembly, as shown in the following figure.
          Figure 1. Fan-Tray Assembly in the Cisco ME 2600X Shelf

          Step 2   Extract the fan-tray assembly partially ( not more than 1 inch) to disconnect the backplane connector and wait until the fan stops.
          Step 3   When the fans have stopped, pull the fan-tray assembly completely out of the shelf, as shown the following figure.
          Figure 2. Fan-Tray Extracted

          Step 4   Slide the new fan-tray assembly into the shelf until the electrical plug at the rear of the tray plugs into the corresponding receptacle on the backplane.
          Step 5   Tighten the M3 screw to a torque value of 4 in-lbs (0.45 N-m) on the fan-tray assembly.

          Stop. You have completed this procedure.
