Applies to:

Goal

 Replace Memory Riser Board in a 7000 Unified Storage system.

Solution

WHAT SKILLS DOES THE ENGINEER NEED: Product Knowledge, Sun ZFS Storage 7000 [C].

TIME ESTIMATE: 120 minutes

TASK COMPLEXITY: 0

PROBLEM OVERVIEW
What: Replace faulty Memory Riser
Where: MR [SR owner to specify], confirm location with BUI:
Maintenance - Hardware - show details - DIMM
Why : MR diagnosed faulty

REPLACEMENT INSTRUCTIONS

See CRU Maintenance Instructions  https://bluegill.us.oracle.com:215/ak8-working-2013-1-4-0/index.php/Maintenance .

See References for a list of other useful troubleshooting documents.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY:
* Shut down appliance.
* Disconnect power cords.

NOTE : For Clustered Systems

It is MANDATORY NOW THAT YOU UNPLUG THE CLUSTRON CABLES (UART0 and UART1 ) and take notice that these cables are crossover connected.

THEY WILL NEED TO BE REPLUGGED IN THE SAME WAY AFTER THE HW REPLACEMENT ACTION HAS BEEN COMPLETED.

Remove a Memory Riser and DIMM


WHAT ACTION DOES THE ENGINEER/ADMINISTRATOR NEED TO TAKE:
1 Take antistatic precautions
2 Remove system from rack
3 Remove top cover - press release button, slide slightly to rear before removing
* If servicing a 7410, lift the air duct to replace DIMMs on the mezzanine board, or remove the mezzanine tray to replace DIMMs on the motherboard

=

2. Identify the memory riser with the faulty DIMM by pressing the Fault Remind button on the air divider.
- If the memory riser Service Action Required LED is off: all DIMMs on this riser are operating properly.
- If the memory riser Service Action Required LED is on (amber): one or more of the DIMMs installed on this riser is faulty or misconfigured or riser is faulty.

3. Lift the memory riser that has its Service Action Required LED lit straight up to remove the memory riser from the memory module socket.

4. To remove the DIMM on the faulty riser do the following:

a. Rotate both DIMM slot ejectors outward as far as they will go. (The DIMM is partially ejected from the socket).
b. Carefully lift the DIMM straight up to remove it from the socket.


5) Install the new Memory Risers and DIMMs

- Unpack the DIMMs and place them on an antistatic mat.
- Ensure that the ejector levers at both ends of the memory module slot are in a fully open position.
- Align the DIMM with the empty slot.

Align the notch in the DIMM with the key in the connector. The notch ensures that the DIMM is oriented correctly.

6. Gently press the DIMM into the slot until the ejector tabs lock the DIMM in place.

- If the DIMM does not easily seat into the connector, verify that the notch in the DIMM is aligned with the key in the connector.
- If the notch is not aligned, damage to the DIMM might occur.

7. Install all the DIMMs on the riser board.

8. Push the memory riser module into the associated CPU memory riser slot until the riser module locks in place.

9. Return system to operational state
* Place top cover on chassis so that it overhangs rear of the unit slightly. Slide forward until it seats
* Close fan cover and engage fan cover latches. Cover must be completely closed for the system to power on
* Reinstall appliance back in original rack location
* Reconnect all cables
* Verify standby power is on - Power/OK LED flashes on front panel about 2 minutes after power cords are plugged in
* Use a pen to press the recessed Power button on the front panel. The Power/OK LED will stay solidly lit. SSH to the Service Processor and check appliance power state
  show /SYS power_state
If off start system
  start /SYS

OBTAIN CUSTOMER ACCEPTANCE
Confirm appliance is in normal state. Check both BUI and client data access

WHAT ACTION DOES THE ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Confirm there are no faults reported in appliance BUI
Maintenance - Problems ("Mark Repaired" any prior related DIMM faults)
Should an error return for the same DIMM, reseat the DIMM and monitor the appliance for further errors

PARTS NOTE:
Check System Handbook for correct part number
