Replacing an SPU

Replacing an SPU

This section describes the precautions and procedures for replacing an SPU.

Context

The new SPU must be of the same type as the one that is to be replaced.

Tool

Before replacing the SPU, you need the following tools:

  • ESD wrist strap or ESD gloves

  • Phillips screwdriver

  • ESD bag

Procedure

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

    Before pulling out the SPU to be replaced, first check the location of the SPU, that is, the cabinet and chassis where the SPU resides, and label it.

  2. Check whether there is any bent pin in the connector of the new SPU.
  3. Power off the SPU to be replaced.

    NOTE:
    • Before replacing an SPU, you must power it off. If you remove an SPU while it is running and then insert a new one, the SPU and its SPC may not work properly.
    • After powering off the SPU, the number of CPUs in the device changes. In this case, sessions reselect CPUs based on the hash algorithm. If the selected CPU is different from the previous one, the session will be interrupted, and the service will re-initiate a connection.

    Use either of the following methods:

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

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

  4. Pull out the SPU.
    1. Put on the ESD wrist strap and connect the ground terminal to the ESD jack on the chassis.
    2. Using the Phillips screwdriver turn the two captive screws counter-clockwise to loosen them, as shown in Figure 3-11 (1).
    3. Turn the ejector levers on the panel of the SPU outward and upward. When the ejector levers and the panel form a 45-degree angle, the SPU is removed from the backplane, as shown in Figure 3-11 (2).
    4. Holding the captive screws, pull out the SPU, as shown in Figure 3-11 (3).

      • Pull out the SPU slowly and smoothly to prevent it from hitting neighboring boards and affecting running boards.
      • When removing an SPU, do not touch any parts on the SPU to avoid damaging it.

    5. Place the removed SPU into the ESD bag.
  5. Insert a new SPU.
    1. Take out the new SPU from the ESD bag.

      • Pull out the SPU slowly and smoothly to prevent it from hitting neighboring boards and affecting running boards.
      • When removing an SPU, do not touch any parts on the SPU to avoid damaging it.

    2. Hold the captive screws of the SPU, and insert the SPU smoothly along the guide rails of the slot until the SPU is completely seated in the slot, as shown in Figure 3-12 (1).
    3. Turn the ejector levers on the SPU outward and upward to form a 45-degree angle, and at the same time push the SPU into the slot. Then, turn the ejector levers inward and downward until the panel of the SPU touches the slot, as shown in Figure 3-12 (2).
    4. Using the Phillips screwdriver, turn the two captive screws clockwise to tighten them, as shown in Figure 3-12 (3).

  6. Check the running status of the new SPU.

    Check the running status of the new SPU in the following ways:
    • Check the RUN indicator on the panel of the SPU. If it is on (green), the SPU is working normally.
    • Check the alarms. If the system does not generate any alarm related to the new SPU, the SPU is working normally.
    • Run the display device command on the console interface. If the SPUs in the corresponding slots are working normally, the following is displayed:

      NIP6860's Device status:
      Slot #    Type       Online    Register      Status      Primary

      - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

  7. Check whether services are working normally.

Follow-up Procedure

After replacing the SPU, collect all tools. If the replaced SPU 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.
