Replacing an SFU

Replacing an SFU

This section describes the precaution and procedure for replacing an SFU.

Context

When replacing a Switch Fabric Unit (SFU), note the following:

  • The NIP6860 has three SFUs. Only one SFU can be replaced independently.
NOTE:

The NIP6830 does not have an independent SFU.

Tool

Before replacing an SFU, you need the following tools:

  • ESD wrist strap or ESD gloves

  • Phillips screwdriver

  • ESD bag

Procedure

  1. Check the location of the SFU to be replaced.

    Before pulling out an SFU that is to be replaced, first determine the location of the SFU, that is , the cabinet, chassis, and slot where the SFU resides.
    • The NIP6860 has one SFU, which resides in slot 11.

    Locate the SFU to be replaced in the chassis and label the SFU.

  2. Prepare a new SFU and check whether there is any bent pin in the connector.
  3. Power off the SFU to be replaced.

    Use either of the following methods:

    • Press and hold the OFL button on the panel of the SFU for six seconds until the OFL indicator is on.

    • In the user view, run the power off slot slot-id command.

  4. Pull out the SFU to be replaced from the chassis.
    1. Put on the ESD wrist strap and connect the grounding terminal to the ESD jack on the rack.
    2. Loosen the two captive screws by turning them counter-clockwise with a Phillips screwdriver, as shown in Figure 3-5 (1).
    3. Turn the ejector levers on the panel of the SFU outward and upward. When the ejector levers and the panel form a 45-degree angle, the SFU is removed from the backplane, as shown in Figure 3-5 (2).

      • Pull out the SFU slowly and smoothly to prevent it from hitting neighboring boards and affecting running boards.
      • Touching parts on the SFU when swapping it may damage the SFU.

    4. Hold the ejector levers on the panel of the SFU and pull out the SFU smoothly from the chassis along the guide rail of the slot. After the SFU protrudes from the chassis by roughly 30 cm to 40 cm, support the lower edge of the SFU with one hand and hold the panel of the SFU with the other hand. Then, pull out the SFU smoothly from the slot, as shown in Figure 3-5 (3).
    5. Place the removed SFU in the ESD bag.

  5. Insert the new SFU into the chassis.
    1. Take out the new SFU from the ESD bag.

      • Pull out the SFU slowly and smoothly to prevent it from hitting neighboring boards and affecting running boards.
      • Touching parts on the SFU when swapping it may damage the SFU.

    2. Support the lower edge of the new SFU with one hand and hold the panel with the other hand. Then, insert the new SFU smoothly into the chassis along the guide rail of the slot, as shown in Figure 3-6 (1). Stop sliding the SFU forward when the ejector levers on the front panel of the SFU reaches the chassis.
    3. Turn the ejector levers on the SFU outward and upward to form a 45-degree angle, and at the same time push the SFU into the slot. Then, turn the ejector levers inward and downward until the panel of the SFU touches the slot, as shown in Figure 3-6 (2).
    4. Using a Phillips screwdriver, turn the two captive screws clockwise to tighten them, as shown in Figure 3-6 (3).

  6. Check the running status of the new SFU.

    Normally, after the new SFU is inserted into the chassis, the SFU automatically communicates with the boards in the chassis. In this case, you can check the running status of the new SFU in the following ways:
    • Check the RUN indicator on the panel of the SFU. If it is on (green), the SFU is working normally.
    • Check the alarms. If the system does not generate any alarm related to the new SFU, the SFU is working normally.
    • Run the display device command on the console interface. If the SFUs are working normally, the following is displayed:

Follow-up Procedure

After replacing the SFU, collect all tools. If the replaced SFU is faulty, fill in the Repair Transmission Sheet and send the faulty module with the Repair Transmission Sheet to the equipment supplier or the specified repair service provider.
