Video - Procedure to replace DE3 Power Supply (1:30)

DISPATCH INSTRUCTIONS
WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?: No special skills required, Customer Replaceable Unit (CRU) procedure
TIME ESTIMATE: 30 minutes
TASK COMPLEXITY: 0

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
PROBLEM OVERVIEW:
What: The power supply/ Cooling Fan Assembly in the DE3 JBOD needs replacement
Where: Chassis S/N: , PSU Slot No. of the device to be inserted here by SR owner
Why : The PSU has failed in the DE3 and should have an amber light on it.

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY?:
Verify that the Redundant Power supply/Fan Unit is optimal . If so , No downtime needs to be scheduled,
and the system can be in full production as they are redundant.

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE?:
1. Locate the PSU by amber LED

The following LEDs are lit when a power supply fault is detected:

* Front and rear Service Required LEDs
* Rear PS Failure LED on the bezel of the server
* Failure LED on the faulty power supply

2. Verify the PSU part number in the System Handbook and re-confirm.

3. Removing the Power Supply as follows.
3.1 Clear access to the Power supply of any cables harnesses or assemblies.
3.2 Ensure the Power supply On/Off switch is in the 'Off' Position.
3.3 Disconnect the power cord tie strap from the power cord , and unplug the power cord from the power supply.
3.4 Remove installed power supply unit by, Grasping the power supply handle, push the release button and slide out power supply.

4. Installing the Power Supply as follows or use the "online" Help Guide.

4.1 On the replacement Power supply verify that the Release button is open .
4.2 Align power supply with empty bay in chassis and slide in .
4.3 Push the lever fully closed until you hear or feel a click.
4.4 Connect AC power cord to new power supply. Use the power cord retaining clips.
4.4 If required , place cable harness or assemblies back into normal position.
4.5 Turn the On/OFF switch to the On position .

5. Verify the replacement by checking for Green LED

IMPORTANT NOTE :
PSU's have a 3 minute Service time limit . When you remove a PSU the
fans on the remaining PSU go to 100 % duty cycle . Testing has shown that
HDD temperatures can exceed their operating temperature when a PSU has
been removed for 3 minutes.

Note: At this time we have not verified that the procedure above is correct or complete .

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:
Confirm there are no faults reported in the Mini cluster BUI. Mark "Repaired" any prior faults related to the PS
