FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS

PROBLEM OVERVIEW: replace a faulty SPARC T5-4 Rear Chassis Subassembly

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

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

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, and order a new part. Handle with caution and package carefully the return part to avoid any damages during shipping.

The server must be fully shut down and the power cords disconnected.

NOTE: Before parts replacement, connectors pins should be inspected to make sure there are no bent pins and/or misaligned connectors, as that can cause a number of problematic symptoms.

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE:

Verify that the rear chassis subassembly needs to be replaced.
Use the server software to determine if the rear chassis subassembly needs to be replaced.
Power off the server.
Disconnect the power cords.
Completely remove the Processor Modules and Main Module from the front of the chassis.
Go to the rear of the server and remove the following components:
- All five fans
- All PCIe carriers or PCIe filler panels Make note of the slots for each carrier or filler panel so that you can install them into the same slots.
- Rear I/O module
You will install these components into the replacement rear chassis subassembly once you have replaced the faulty subassembly.
Locate the five green mounting screws for the rear chassis subassembly. The green screws are accessed from the front of the chassis after removing the PM, and MM.
Using a Phillips screwdriver, loosen the five screws that secure the rear chassis subassembly to the system.
Slide the rear chassis subassembly out and away from the server.

Install the Rear Chassis Subassembly

Slide the rear chassis subassembly into the server.

Using a Phillips screwdriver, tighten the four green screws to secure the rear chassis subassembly in the server.
Tighten the screws in the following order:
1. Lower right screw.
2. Upper left screw.
3. Upper right screw.
4. Lower left screw.
5. Lower center screw
Remove the connector covers from the replacement rear chassis subassembly.
Install the components removed from the front od the server.
Install the following components back into the rear of the server:
- All five fans
- All PCIe carriers or filler panels – Verify that you are installing the PCIe cards back in their original slots using the notes that you took when removing the cards from the slots earlier.
- Rear I/O module
Connect the power cords.
Power on the server.
