Replacing the SPC of the SPU

Replacing the SPC of the SPU

This section describes the precautions and procedures for replacing the SPC of the SPU.

Context

The new SPC must be the same type as the one to be replaced.

Tool

Before replacing the SPC, you need the following tools:

  • ESD wrist strap or ESD gloves

  • Phillips screwdriver

  • ESD bag

Procedure

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

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

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

    NOTE:
    • Before replacing an SPC, power it off. If you remove a SPC while it is running and then insert another one, the SPC and its SPU may not work properly.
    • After powering off the SPC, the number of device CPUs. 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 SPC for six seconds until the OFL indicator turns red for one second and then turns off.

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

  4. Pull out the SPC to be replaced from the SPU.
    1. Put on the ESD wrist strap and connect the ground terminal to the ESD jack on the rack.
    2. Using the Phillips screwdriver, turn the two captive screws counter-clockwise to loosen them, as shown in Figure 3-13 (1).
    3. Holding the captive screws of the SPC, pull out the SPC, as shown in Figure 3-13 (2).

      • Pull out the SPC slowly and smoothly so that it does not bump into neighboring boards and cause a malfunction.
      • When removing an SPC, do not touch the parts on it to avoid damaging the SPC.

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

      • Pull out the SPC slowly and smoothly so that it does not bump into neighboring boards and cause a malfunction.
      • When removing an SPC, do not touch the parts on it to avoid damaging the SPC.

    2. Holding the captive screws of the SPC, insert the SPC smoothly along the guide rails of the slot until the SPC is full inserted, as shown in Figure 3-14 (1).
    3. Using the Phillips screwdriver, turn the two captive screws clockwise to tighten them, as shown in Figure 3-14 (2).

  6. Check the running status of the new SPC.

    Check the running status of the new SPC in the following ways:
    • Check the STATUS indicator on the panel of the SPC. If it is on (green), the SPC is working normally.
    • Check the alarms. If the system does not generate any alarm related to the new SPC, the SPC is working normally.
    • Run the display device command on the console interface to view the running status of SPUs. If the SPUs in the corresponding slots are working normally, the following is displayed:
      <sysname> display device
      NIP6830's Device status:

      6         CLK        Present   Registered    Normal      Master                 
      7         CLK        Present   Registered    Normal      Slave                  
      8         PWR        Present   Registered    Normal      NA                     
      9         PWR        Present   Registered    Normal      NA                     
      10        FAN        Present   Registered    Normal      NA 
      
    • Run the display device pic-status command on the console interface to view the running status of SPCs. If the SPCs on the corresponding SPUs are working normally, the following is displayed:
      <sysname> display device pic-status
      Pic-status information in Chassis 1:

  7. Check whether services are working normally.

Follow-up Procedure

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