Attaching The Mounting Hardware To The Rack - IBM EMX0 PCIe Gen3 Installing

Note: During this procedure, put nut clips in the (D) marks. Then, during the procedure to attach
the mounting hardware to the rack, put rail pins in the (C) marks.
9. Repeat step "8" on page 7 to place four marks on the corresponding mounting holes on the rear-right
side of the rack. Insert nut clips in the (D) marks.

Attaching the mounting hardware to the rack

Find information about attaching the mounting hardware to the rack and then installing the rails into the
rack. The information is intended to promote safety and reliable operation, and includes illustrations of
the related hardware components and shows how these components relate to each other.
About this task
Attention: To avoid rail failure and potential danger to yourself and to the unit, ensure that you
have the correct rails and fittings for your rack. If your rack has square support flange holes or
screw-thread support flange holes, ensure that the rails and fittings match the support flange
holes that are used on your rack. Do not install mismatched hardware by using washers or spacers.
If you do not have the correct rails and fittings for your rack, contact your IBM reseller.
Important: To complete this procedure, it is suggested that you use two people to attach the rail
assembly to the rack. Position one person in front of the rack and one person at the back of the rack.
Procedure
1. Gather the rail kit parts that you need during this procedure.
The rail kit includes the following parts:
Note: The installation of the EMX0 PCIe3 expansion drawer does not require usage of all parts that are
included in the rail kit.
• M3 flat head screws (used only with FC 5887)
• L-shaped brackets (used only with FC 5887)
• M5 slotted large round head screws and M5 slotted no head screws to accommodate various racks
• Nut clips for racks with round holes
• Nut clips for racks with square holes
• M5 black hex head screws
• Rails
2. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged
into a ground jack or connected to an unpainted metal surface. If not, do so now.
3. Rotate down the front and back clamps (C) on the left and right rails.
4. On each rail, remove the tape that is holding the spring (B) to the rail. Hook the end of the spring
around the circular standoff on the rail.
