ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

PROBLEM OVERVIEW: SPARC T8-1 Power Supply Replacement

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

Note:

This is a hot service procedure that can be performed by Customers while the server is running.
The server's redundant power supplies support concurrent maintenance, which enables you to remove and replace a power supply without shutting down the server, provided that the other power supply is online and working.
If a power supply fails and you do not have a replacement available, leave the failed power supply installed to ensure proper airflow in the server.

WHAT ACTIONS ARE REQUIRED?:

Damage Alert:

Perform a visual inspection of the replacement part to make sure that there are no damaged components, connectors, bent pins, damaged packages during shipping, etc). If the part is damaged, don't install it into the system, order a new part. Handle with caution and package carefully the return part to avoid any damages during shipping.

Confirm the Power Supply failure and it's location

1. Confirm which Power Supply is to be replaced. When looking at the server from the rear PS0 is to the left and PS1 is to the right.

2. If the specific power supply to be replaced is not yet known check the status LEDs to identify the failed Power Supply. A failed PSU should have it's amber "service required" LED lit. A working PSU will only have it's green "AC OK" LED lit.

3. If the service is to be performed while the system is up and running confirm that the second PSU is online and working properly.

4. If a replacement Power Supply is not yet available leave the failed supply in place to provide proper airflow within the system until the replacement is available. You may notice that the failed Power Supply's fans are still turning. This is ok and the power supply may be removed while the fans are still spinning.

Replace the Power Supply

1. Gain access to the rear of the server where the faulty power supply is located.

2. If the cable management arm (CMA) is installed, disconnect both CMA left-side connectors and move the CMA out of the way.

Caution:

When disconnecting the CMA left-side connectors, use your arm to support the CMA so that it does not hang down under it's own weight and stress the right-sdie connectors; otherwise, the CMA might be damaged. You must continue to support the CMA until you have reconnected both of the left-side connectors.

3. Disconnect the power cord from the failed power supply.

4. Press the release latch to the left to open the ejector arm.

5. Slide the power supply out of the chassis and set it aside on an antistatic mat.

Caution:

Whenever you remove a power supply, you should immediately replace it with another power supply; otherwise, the server might overheat due to improper airflow.

6. Remove the replacement power supply from its packaging and place it on an antistatic mat.

7. Align the power supply with the empty power supply chassis bay.

8. Slide the power supply into the bay until it is fully seated. (an audible click will be heard when it is fully seated)

9. Reconnect the power cord to the power supply.

10. Verify that the amber LED on the replaced power supply and the Service Required LEDs on the front and rear of the chassis are not lit.

11. Return the Server to operation

a. If you pulled the server out of the rack to make it easier to remove the power supply, push the server into the rack until the slide-rail locks (on the front of the server) engage the slide-rail assemblies.
b. If a cable management arm is installed and was removed to access the power supply reattach the two CMA connectors.
c. Check all power and data cables to ensure that no connections were disturbed during the service.
d. Verify that the Power/OK indicator led lights steady on and that system is operating properly.

How to verify the Power Supply is working properly

1. Log into ILOM to check power supply status.

Example:

-> show /SYS/PSx

/SYS/PSx
Targets:
ERR
F0
FAN_ERR
INPUT_POWER
I_+12V
I_+12V_STBY
I_IN
I_OUT_ERR
I_OUT_STBY_ERR

T_AMB
T_ERR
V_+12V
V_+12V_STBY
V_IN
V_IN_ERR
V_OUT_ERR
V_OUT_OK
V_OUT_STBY_ERR

Properties:
type = Power Supply
ipmi_name = PSx
fru_description = A266_Power_Supply
fru_manufacturer = DELTA ELECTRONICS (THAILAND)
fru_part_number = 7333459
fru_rev_level = 01
fru_serial_number = 465824T+1712D30592
fault_state = OK
clear_fault_action = (none)

Commands:
cd
set
show

2. Check ILOM event log to see if there are any errors related to the power.

-> show /SP/faultmgmt
-> show /SP/logs/event/list
