CAP PROBLEM OVERVIEW: Mx-32 - How to Replace a Faulty Power System Cage

To report errors or request improvements on this procedure, please go to My Oracle Support, and put a comment on Doc ID: 1547438.1

This Canned Action Plan describes all necessary steps to replace a Faulty Power System Cage, which are described in great detail in the SPARC M5-32 Server Service Manual, Servicing the Power System Cage.

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.

NOTICE: The component specified for replacement in this action plan requires a Genie Lift. The lift is required not only for the safety of the servicing engineer, but also for the successful implementation of the replacement procedure. Any of the following parts may be ordered to satisfy the Genie Lift requirement:

370-4286 Genie Lift w/straddle base.
371-4170 Genie Lift w/Cntr-weight Base Adj
370-6889 Genie Lift w/counter-weight base
370-6888 Genie Lift w/standard base

Depending on the region/country, the order lead-time for the Genie Lift may be longer than other parts.

DO NOT ATTEMPT THE REPLACEMENT PROCEDURE WITHOUT THE REQUIRED GENIE LIFT.

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED: Mx-32 Product Training/Experience

TASK COMPLEXITY: 4

TIME ESTIMATE: 180 minutes COLD replacement

FIELD ENGINEER INSTRUCTIONS

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

Physical Domains must be shut down. Server must be powered off.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Caution:

The empty power system cage weighs 207 lbs (94kg). Two Oracle engineers are required to move it.
A lifting device like a Genie Lift is needed during removal/insertion of the power system cage
To replace the power system cage, prepare ESD safe storage space for 2 Power Signal System Distribution boards, 12 Power Supplies, 1 Front Filler panel and 2 Power System Cages
Record the slot number for each component, and stack them in order. You must place them back in their original order later

1. Halt the server and turn off all AC power:

Turn the key switch on the Front Panel of the server to the Service position.
Gracefully shutdown the server by running the ILOM command "stop /System" (requires Oracle ILOM Reset and Host Control (r) user role).
Turn off all external breakers for the server.
For maximum safety, disconnect all six power cords from their respective AC outlets.

2. Verify that it is safe to disconnect the power cords:

All six external breakers for the server must be in the Off position.
All six power cords for this server must be unplugged from their respective AC outlets.
No LEDs on the server should be lighted.
You should not hear any fans running in the server.

3. Remove the front filler panel to access the power system cage, check M5-32 How to Service the Front Filler Panel Assembly [ID 1539427.1] for details

4. Remove both Power Signal Distribution boards (PSDBs) from the Power System Cage, check M5-32 - How to Replace a Faulty Power Signal Distribution Board (PSDB) [ID 1528156.1] for details

5. Remove all 12 Power Supplies from the Power System Cage, check M5-32 How to replace a Faulty Power Supply [ID 1530037.1] for details

6. At the rear of the server, disconnect all six AC line filters from the rear of the power system cage:

use a T20 Torx screwdriver to loosen two captive screws from an AC input filter
pull the AC filter out of the slot approximately 2 inch (50 mm)

7. Prepare for removal, and remove the Power System Cage from the server:

place the Genie Lift under the power system cage to support it
remove eight T20 Torx screws from the front of the power system cage
use the lifting device to carefully pull the power system cage out of the server, until it hits the locks on the sides of the power system cage
press the lock buttons on the upper sides of the power system cage to unlock them, then remove the power system cage from the server
place the removed Power System Cage on an ESD safe surface
put the removed Power System Cage into its ESD safe packaging

8. Prepare for installation, and install the Power System Cage into the server:

remove the Power System Cage from its ESD safe packaging
lift the replacement Power System Cage from the ESD safe surface, using the Genie Lift
carefully push the power system cage into the server
shoulder areas on the sides of the power system cage fit into openings at the sides of the cabinet
tighten eight T20 Torx screws at the front of the power system cage

9. Install all 12 Power Supplies into the Power System Cage, check M5-32 How to replace a Faulty Power Supply [ID 1530037.1] for details

10. Install both Power Signal Distribution boards (PSDBs) into the Power System Cage, check M5-32 - How to Replace a Faulty Power Signal Distribution Board (PSDB) [ID 1528156.1] for details

11. At the rear of the server, reconnect all six AC line filters to the rear of the power system cage:

push the AC filter fully into the slot
use a T20 Torx screwdriver to tighten the two captive screws

12. Install the front filler panel back into the power system cage, check M5-32 How to Service the Front Filler Panel Assembly [ID 1539427.1] for details

13. Verify all six external breakers are still in the Off position.

14. Warn bystanders that you are preparing to restart the server.

15. Turn on all AC power and start the server:

Connect all six AC cords to their respective AC outlets.
Turn on all external breakers for the server.
Turn the key switch on the Front Panel of the server to the On position.
Start the server by running the ILOM command "start /System" (requires Oracle ILOM Reset and Host Control (r) user role).

16. Prepare the failed Power System Cage outside the datacenter for return to Oracle.

The power system cage is a large and heavy component (>200lbs). Shipment companies used for standard FRU return will not accept such a large package for return delivery to Oracle. Please contact ron.oclair@oracle.com for special handling instructions.
