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.

REMOVAL/REPLACEMENT INSTRUCTIONS:

PROBLEM OVERVIEW: Snap-in Slide Rail Rackmount kit Replacement

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

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.

If the system is still up and functioning, the customer should perform an orderly and graceful shutdown of applications and OS. Then power off the server and remove the AC power cords from the system. A data backup is not a pre-requisite but is a wise precaution.

NOTE: For ALL scenarios where an AC power down or AC power cycle is required for a T7-x server, please always use the steps in doc 1571054.1 prior to physically removing AC power cables from the server.

WHAT ACTIONS ARE REQUIRED?:

Disassemble the new Replacement Snap-in Slide Rail/Mounting Bracket you are preparing to Install

1. Unpack the slide rails. The rackmount kit contains two slide rails, two mounting brackets, and optional securing screws.
2. Locate the slide rail lock at the front of the new snap-in slide rail assembly you want to replace.

a. Press and hold the slide rail lock toward the direction of the arrow while you pull the mounting bracket out of the slide rail assembly until it reaches the stop.
b. Push the mounting bracket release button toward the front of the mounting bracket, and simultaneously withdraw the mounting bracket from the slide rail assembly.
c. If needed, repeat for the remaining slide rail assembly.

Remove Server and Faulty Rackmount Hardware from Rack

1. Disconnect all the cables and power cords from server.
2. Extend the server to the maintenance position
3. Disconnect the CMA (Cable Management Arm). Pull out the retention pin that secures the CMA to the rack rail. Slide the CMA out of the end of the inner glide. The CMA is still attached to the rack, but the server is disconnected from the CMA.
4. From the front of the server, press inner rail release buttons and pull the server forward until it is free of the rack rails.

Caution – This procedure requires a minimum of two people because of the weight of the server. Attempting this procedure alone could result in equipment damage or personal injury.

5. Set the server on a sturdy work surface.
6. Locate the faulty slide rail or mounting bracket by removing it and pulling it completely out of the rack or off the chassis.

Replace the damaged Snap-in Slide Rail(s) Rackmount Hardware

If mounting bracket was damaged; position a mounting bracket against the chassis so that the slide rail lock is at the server front, and the five keyhole openings on the mounting bracket are aligned with the five locating pins on the side of the chassis. With the heads of the five chassis locating pins protruding though the five keyhole openings in the mounting bracket, pull the mounting bracket toward the front of the chassis until the mounting bracket clip locks into place with an audible click. Verify that the rear locating pin has engaged the mounting bracket clip.

Note - The mounting brackets are identical and can be installed on either side of the chassis.

If slide rail was damaged; replace new slide rail where faulty slide rail was removed by making sure the new slide rail is installed identically as the previous damaged slide rail was.

Racking Server after Replacement of Damaged Mounting Bracket/Slide Rail

Use this procedure to install the server chassis, with mounting brackets, into the slide rail assemblies that are mounted to the rack:

Caution - This procedure requires a minimum of two people because of the weight of the server. Attempting this procedure alone could result in equipment damage or personal injury.

1. Push the slide rails into the slide rail assemblies in the rack as far as possible.
2. Raise the server so that the rear ends of the mounting brackets are aligned with the slide rail assemblies that are mounted in the rack.
3. Insert the mounting brackets into the slide rails, and then push the server into the rack until the mounting brackets encounter the slide rail stops (approximately 12 inches, or 30 cm).

Caution - When inserting the server into the slide rail, ensure that both the top and bottom mounting lips of the mounting brackets are inserted into the slide rail. The server should slide forward and backward easily if correctly installed. If the unit does not slide easily, ensure that each mounting lip is inserted properly. If the mounting brackets are not inserted properly, the unit might fall when it is removed from the rack.

4. Simultaneously push and hold the green slide rail release buttons on each mounting bracket while you push the server into the rack.
5. Continue pushing until the slide rail locks (on the front of the mounting brackets) engage the slide rail assemblies. You will hear an audible click.

Caution - Verify that the server is securely mounted in the rack and that the slide rail locks are engaged with the mounting brackets before continuing.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:
