1 Introduction 1.1 Scope This Operational Instruction describes the procedure to replace a APUB and APUB2 processor board.

2 Procedure 2.1 Prerequisites 2.1.1

Conditions

The following condition must apply before this procedure can be completed: 

A work order is received or an AP FAULT alarm is received.



A technician is available on site.



The technician is able to login with Administrators rights.



One of the two APUB board should be in active and working condition.

2.1.2

Data

The following data must be known to complete this procedure: 

The user name and password valid for a user with administrative rights on the node.



The Bios and IPMI FW is available, if upgrade is needed.



The document "APHW Boards and CN-I Information" is needed, if Bios and IPMI FW upgrade is needed.

2.1.3

Special Aids



Torx #8 screw-driver for the removing of board.



Chassis/cabinet - Torx #10.



An APUB replacement board



A grounding strap. To be used when exchanging the equipment.

In case of Bios or IPMI FW upgrade is required you need: 

The Bios and/or IPMI FW.



The document "APHW Boards and CN-I Information".

2.2 Actions Connect to Active APUB board and Login 1. Connect to the active node. Go to Operational Instruction AP, User Session, Initiate. Perform the steps in that Operational Instruction and return to Step 2. 2. Was it possible to login? Yes Go to Step 3. No Go to Step 41. 3. Print the Board slot numbers. Enter command hwmls Note: Check received in the work order is the one of faulty board. This info will be used in next steps.

Check BIOS and IPMI FW Version, active board 4. Check the Bios version on active boards. Use command wmic CSPRODUCT List Status. 5. Check the state of firmware on active board. Use command ipmi_upg -f. Note: Take note of Running IPMI FW state and IPMI FW revision. Block Faulty Board 6. Check whether the faulty APUB board is existing or not in the slot? Yes Go to Step 7. No Go to Step 41. Note: For the slot number, Refer Step 3. 7. Block the faulty APUB board. Use command hwmblk -s < slotnumber> -f Note: < slotnumber> is the slot no of the faulty board. Refer Step 3. 8. Wait until the MIA LED on the APUB board to be replaced is switched on. Use command hwmls -s < slotnumber> -l | findstr -I MIA. Note: < slotnumber> is the slot no of the faulty board. Refer Step 3. Disconnect Cables on Faulty Board 9.

Warning! Be careful when removing the cables. They are easily damaged. 10. 10. Disconnect the ethernet and external alarms cables from the faulty board in the following order, see APG43 Cable Reference.

Diconnect SAS-0 on the faulty Board

12. Note: 13. It is important that the cables will be reconnected in the same channels (SAS-0 respective SAS-1) where they were removed from. Replace Faulty APUB Board 12. Replace the faulty board with the replacement board. Note: When you have loosened the faulty board from the cabinet a few millimeters, check that all screws are loose - they have a tendency to still be connected by a half turn. Reconnect cables 13. Connect the ethernet and external alarms cables in the following order, see APG43 Cable Reference: Table 3

15. Note: 16. It is important that the cables is connected in the same channels (SAS-0 respective SAS-1) where they were removed from.

On active APUB board, integrate the replaced board 15. Integrate the replaced board. Use command hwmdeblk -s < slotnumber> Note: < slotnumber> is the slot number of the repaired board. Refer Step 3. Note: Check power LED is ON and MIA Led is OFF. 16. Disconnect from the active node. Go to Operational Instruction AP, User Session, End. Perform the steps in that Operational Instruction and return to Step 17. Perform Single Node Recovery 17. Go to Operational Instruction AP, System Disaster Recovery(1M) and perform a single node recovery on the replaced APUB board. Return to Step 18. Check BIOS and IPMI FW Version, replacing board. 18. Connect to the replaced node. Go to Operational Instruction AP, User Session, Initiate. Perform the steps in that Operational Instruction and then return toStep 19. Upgrade Bios for APUB boards 19. Print the APUB Boards Product Number and Revision. Enter command hwmls –l Note: Make a note of “Product Number:” and “Product Revision State:” for both the APUB Boards. That info are used to check the latest released IPMI and bios. 20. Check the Bios version on replaced boards. Enter command: wmic CSPRODUCT LIST status 21. Is replaced Board's BIOS version identical to Active board's one, as got at Step 4? Yes Go to Step 23. No Go to Step 22. 22. Go to "APHW Boards and CN-I Information", APHW CN-I’s - section to upgrade Bios upgrade Bios on active/passive APUB board whichever is lower, contact next level support to get CNI info and return toStep 23. Upgrade FW for APUB boards 23. Check the firmware state and revision of the upgraded board. Use command

ipmi_upg -f Note: Compare Running IPMI FW state and IPMI FW revision with output of Step 5. 24. Is the IPMI firmware of replaced Board identical to Active's one ? Yes Go to Step 40. No Go to Step 25. 25. Check watchdog status. Use command hwmls -l | findstr -i watchdog. Note: If printout comes as "Watchdog Status: OFF" then watchdog is in disable state. Note: If printout gives "Watchdog Status: " then watchdog is in enable state. Note down the value of watchdog. 26. Disconnect from the replaced node. Go to Operational Instruction AP, User Session, End. Perform the steps in that Operational Instruction and return toStep 27. 27. Connect to the active node. Go to Operational Instruction AP, User Session, Initiate. Perform the steps in that Operational Instruction and return to Step 28. 28. Disable the watchdog on both nodes. Use command hwmset -n own disable hwmset -n other disable. 29. Stop the APBM and HWM server.cluster res ACS_APBM_Server_0 /offcluster res ACS_APBM_Server_1 /off 30. Upgrade firmware. Use command ipmi_upg -U -S SCBRP_MasterIP:slot. Note: where is the path to the firmware file. 31. Check the firmware version of the upgraded board. Use command ipmi_upg -f -S scbrep_ipaddress:slot. 32. Was the upgrade of firmware successful? Yes Go to Step 33. No Go to Step 41.

33. Restart APBM and HWM server. cluster res ACS_HWM_Server_0 /on cluster res ACS_HWM_Server_1 /on. 34. Select the appropriate action according to Step 25. Enable watchdog. Go to Step 35. Disable watchdog. Go to Step 37. 35. Enable watchdog in both nodes. Use command hwmset -n own -t enable hwmset -n other -t enable. Note: Use value of the watchdog as noted in the Step 25. 36. Go to Step 38. 37. Disable the watchdog on both nodes. Use command hwmset -n own disable hwmset -n other disable. Note: It is recommended that watchdog be enabled with a default value of 120. 38. Check the state of firmware on replaced board. Use command hwmls -s < slotnumber> -l. 39. Check any alarm(s) is present on node. Use command alist. Note: Take appropriate actions to solve any alarm. 40. Disconnect from the active node. Go to Operational Instruction AP, User Session, End. Perform the steps in that Operational Instruction and return to Step 42. Contact Next Level of Support 41. Consult the next level of maintenance support.
