Chapter 3. Rail kit installation instructions
This chapter includes information about rail kit installation instructions.
DM/DE Series 2U24 3U 4U rail kit installation instructions
The Rail can be either installed on a standard square-hole four-post rack or a standard round-hole four-post
rack by using the round-to-square hole adaptor brackets. Before you begin, verify that you have the correct
rail type by examining the PN label located on the rail (PN: SM17A38397).

Installing Rail to round-hole four-post rack
DM/DE Series 2U12 rail kit installation instructions
Using this rail kit, a 2U 12-drive enclosure can be installed in a four-post rack.
Before you begin
The rail kit includes the following items:
• A pair of slide rails for four-post racks with alignment screws installed for the square-hole rack
• (Optional) rack alignment guide tool
• Flat-head M5 screws pre-installed in rails, qty 8
• Round-head M5 screws pre-installed in rails, qty 2
• Alignment screws
Verify that you have the correct rail type by examining the PN label located on the outer box for the following:
• Four-Post: SM17A3839
The kit includes the following types of screws:
12 ThinkSystem DM7000x Hardware Installation and Maintenance Guide

Type of hardware Description Quantity
Flat-head M5 screw; 14
mm long
You use six M5 screws for attaching the rails to
the rack, and two M5 screws for attaching the
brackets at the back of the enclosure to the
brackets at the back of the rails.
8
Round-head M5 screw;
12 mm long
You use these screws to attach the enclosure
to the rails.
2
Alignment screws for
racks with square holes
9.4 mm (head) X 7.5 mm
(length)
The 9.4mm head screws align the rails in the
square-hole rack, 2 in each of 4 corners.
Note: Alignment screws for square-hole racks
come pre-installed in the rails.
8
Alignment screws for
racks with round holes
7 mm (head) X 7.5 mm
(length)

About this Procedure
• You can install the enclosure in either a square-hole or round-hole rack.
• You must use only the screws that are provided in the kit.
Step 1. Determine where you want to install the enclosure in the rack.Use the rack alignment guide tool to
ensure that you install the enclosure at the same level on either post of the rack.
Note: When possible, install enclosures starting at the bottom of the rack and working up, so that
you can use the enclosures underneath as a guide for installing the next set of rails.
Step 2. Remove the M5 screws from each of the rail ends and the side brackets and saved. Make sure to
leave the 8 outer alignment screws (9.4mm head for the square-hole rack) in the rail flanges for
proper alignment in the rack.
a. If you have a round-hole rack, remove the eight pre-installed square-hole rack alignment
screws and install the eight round-hole rack alignment screws.
Note: Ensure that you use the screws that are appropriate for your rack.
b. Place the rail inside the rack where you want to install the enclosure, and align the alignment
screws on the rail with the holes on the front post of the rack.
c. Extend the rail to the back post of the rack until the flanges on the rail touch the inside of the
rack.
d. Insert one flat-head M5 screw through the hole in the front of the rack, and two flat-head M5
screws through the holes at the back of the rack.
Chapter 3.Rail kit installation instructions 13

e. Repeat these steps for the other rail.
Step 3. Place the back of the enclosure (the end with the connectors) on the rails.
Attention: A fully loaded enclosure weighs approximately 5 lb (29 kg). Two persons are required
to safely move the enclosure.
Step 4. Carefully slide the enclosure all the way onto the rails.
Note: If applicable, you might need to remove the shelf end caps or the system bezel to secure the
enclosure to the rack post; if so, you need to replace the end caps or bezel when you are done.
Attention:
• You might need to adjust the rails to ensure that the enclosure slides all the way onto the rails.
• Two M5 screws are used to secure the enclosure to the back of the rails. You might need to
remove the M5 screws on the inner rail to ensure that the enclosure slides all the way back.
Attention: Do not place additional equipment on the rails after you finish installing the enclosure.
The rails are not designed to bear additional weight.
Step 5. Secure the enclosure to the front of the rack and rails by inserting two round-head M5 screws
through the mounting brackets (pre-installed on either side of the front of the enclosure), the holes
on the rack, and the holes on the front of rails.
