DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED:
Experience with 7120 NAS hardware and administration

TIME ESTIMATE: 30 mins

PROBLEM OVERVIEW:
What: Replace faulty memory DIMM
Where: DIMM location Proc/DIMM slot to be entered by TSC, refer to BUI for slot locations:
Maintenance - Hardware - show details - DIMM
Why : A DIMM has been diagnosed faulty

REPLACEMENT INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:
* Shut down the appliance
* Disconnect power cords from rear panel of storage controller. Verify that cables will not be damaged or interfere when the storage controller is extended from the rack.

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:
1 Remove server from rack
1 Remove top cover.

3. Remove DIMM(s)
3.1 Identify the DIMM slot on the CPU board where the DIMM will be replaced

3.2 The DIMM fault LEDs in the DIMM slot ejector levers indicate which DIMM has failed. To light the fault LED push the small blue button on the CPU board labeled "Press to see fault"
3.3 Rotate both DIMM slot ejectors outward as far as they will go to partailly eject the DIMM from the socket
3.4 Carefully lift the DIMM straight up to remove it from the socket

4Install DIMM(s)
4.1 Ensure that the ejector tabs are in the open position as far as they will go.
4.2 Line up the replacement DIMM with the connector.

4.3 Align the notch in the DIMM with the key in the connector.
4.4 Push the DIMM into the connector until the ejector tabs lock the DIMM in place.
4.5 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 will likely occur.

5. Return system to operational state
5.1 Place top cover on the chassis so that it overhangs the rear of the storage controller, slide the top cover forward until it seats.
5.2 Close fan cover and engage the latches. NOTE: The cover must be completely closed for the storage controller to power on.
5.3 Ensure covers are secure and reinstall the appliance back in its original rack location.
5.4 Reconnect all of the cables to the back of the storage controller.
5.5 Verify that standby power is on, indicated by the Power/OK LED flashing on the front panel about two minutes after the power cords are plugged in.
5.6 Use a pen to press and release the recessed Power button on the storage controller front panel. The Power/OK LED next to the Power button lights and remains lit. SSH to the service processor (SP) and check appliance power state
show /SYS power_state
If status is off power up the appliance
start /SYS

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

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

PARTS NOTE:
Replace memory DIMMs in pairs and ensure part numbers match.
4GB (2x2GB) Memory: F541-1313 or F541-3360
8GB (2x4GB) Memory: F541-1304
