How to replace SPU card on 9200.

Solution

SPU Removal:

Note: Prior to remove SPU for replacement please make sure a console connection is available to this card, connect and run the command show bootparams and keep a copy of the output of the bootparams that were configured on slot0 or slot 1. You will need these settings when you configure the bootparams on the replacement card.

To remove a processing unit:

1. Identify which SPU, either slot 0 or 1, is in the Standby state. This can be identified by an amber Active light.

     The green Active light is the Active card and should not be touched or service could be affected or you can run the command “show status” to identify the Standby SPU card.

2. If SPU 1 has to be replaced and it is active, you will need to switchover to 0 prior to performing the swap of the SPU. You can access the cli and issue the command switchover 0 active, verify the switchover is complete and slot 1 should now be the standby.

3. Unscrew the two thumb screws located on each side of the processing unit with a screwdriver. The screws are spring-loaded and will be pushed forward, but will not fall out of the processing unit.

4. Place one or two fingers behind the slide latches and push each one toward the center of the processing unit. This action sends a signal to the SPU to shut down the card. Wait 30 seconds before moving on to step 5. Each slide latch travels 0.28 inches (0.71 cm) before stopping.

5. Hold each ejector lever between your thumb and index finger and pivot each lever away from the center of the processing unit. This action disengages the processing unit from the mid-plane, severing all electrical contact to the processing unit.

6. Hold the processing unit’s front bezel and pull it out of the chassis. The processing unit rides on the card rails until it is completely removed from the chassis. The processing unit should only be handled by the sides. Do not hold the card by the front bezel or the card can flex and be damaged.

7. Place the processing unit in an anti-static bag, and in a safe place.

 
SPU Replacement:

To replace a processing unit:

1. Insert the processing unit into the flared opening of the upper and lower slide rails. The processing unit should only be handled by the sides. Do not hold the card by the front bezel or the card can flex and be damaged. The rails guide the processing unit to engage the mid-plane connector squarely.

2. Push the processing unit completely into the Net-Net 9200 chassis, until it is almost flush with the front face of the chassis. Make sure that the slide latches are pushed toward the center of the card before proceeding.

3. Swing the ejector levers so that they are perpendicular to the front face of the Net-Net 9200.

4. Pivot the ejector levers inward toward the mid plane, making sure that the notch on the outer side of each ejector lever catches the processing unit frame’s front lip on the front of the chassis. This action draws the processing unit fully into the chassis.

5. Push the ejector levers completely against the processing unit’s front panel. You will feel resistance when inserting processing units into the chassis from the EMI mesh gasket pressing on adjacent cards or on the chassis.

6. Slide the slide latches away from the center of the processing unit. Each slide latch travels 0.28 inches (0.71 cm) before stopping. Each slide latch covers the cut-out portion of the ejector levers:

7. Screw the thumb screws into the chassis with a #2 Phillips screwdriver. This creates the final connection between the processing unit and the chassis.

8. On the CLI issue the show status command. The status for the slot should show booting. Wait about 3 minutes for the SPU to boot and enter a RUNNING state:

Set Boot parameters (with SPU reset):

Once the SPU is in standby state you can edit the bootparams on the card.

1. Execute the command set bootparams

 This will bring you through the current bootparams settings. You need to change them to match what was on the card you removed. (Refer to the output you captured prior to remove the card)

2. After the virtual management IP address and gateway have been changed or confirmed, the system issues the following message before returning you to the ACLI:

 Boot parameters have been updated and will take effect on the next reboot.

3. Once the bootparams changes are complete you will need to reset the card by issuing the command: reset card <slot>

4. Run the show status command and verify SPU is now in a Running Standby state

5. After about 10 minutes if you wish to test a failover to this card you can by running the command switchover <slot> active

6. Verify the chassis is back into service with a show health. All cards should be in either an ACTIVE or STANDBY state and show a health score of 100.

 
FTP the Software Images onto the new SPU card:

Note: all the Images present in SPU 0 must be uploaded in SPU 1

1. Give the command show images to check which Images are stored on the new SPU

Repeat all of the above steps to replace the other SPU card.
