Step 1. Identify the Static Rail Kit Contents
Locate the components for installing the rail kit assembly:
•Two static rails.
•Two chassis rails.
•Two Velcro straps.
Step 2. Install and Remove Tool-less Static Rails (Four-Post)
1. Position the left and right rail end pieces labeled FRONT
facing inward and orient each end piece to seat in the holes on
the front side of the vertical rack flanges.
2. Align each end piece in the bottom and top holes of the first
U.
3. Engage the back end of the rail until it fully seats on the
vertical rack flange. Repeat these steps to position and seat
the front end piece on the vertical flange.
4. To remove the rails, pull on the latch release button on the
end piece midpoint and unseat each rail.
Step 3. Configure Flush-Mount Static Rails (Two- or Four-Post)
Note: The rails must be converted to tooled rails
to install in threaded four-post or flush-mount two-post
racks.
1. Lay both rails with the end pieces facing up. Remove the
two screws on the front end pieces and rotate each piece 180
degrees.
2. Reattach both end pieces with the two pairs of screws.

Step 4. Install Flush-Mount or Center-Mount Static Rails (Two-Post)
Note: To configure your rails for a tooled flush-mount
installation, refer to step 3.
1. Attach right and left mounting rails to the front mounting flanges
with two pairs of screws.
2. Slide each flush-mount adjustable bracket forward against the two-
post rack. Secure each side to the mounting flange with two pairs of
screws .
3. For a center-mount installation:
1) Push the back brackets toward the back of the right and left
mounting rails.
2) Attach the fixed center mount brackets to the front mounting
flanges with two pairs of screws.
3) Slide both of the back brackets forward against the two-
post rack and secure each side to the mounting flange with two
screws.
Step 5. Configure Four-Post Threaded Static Rails
Note: To configure your rails for a tooled installation,
you must perform step 3 and then perform the following
steps for the back brackets.
1. Press the rail release button on each rail to disengage the
back brackets.
2. Rotate the back brackets 180 degrees so that the tooled end
piece is in the back position.
3. With the end pieces positioned outward, align and rejoin
the midsections. Slide the back brackets into place until the
release button engages.

flanges with two pairs of screws.
2.Slide the back brackets forward against the back mounting
flanges and secure the brackets using two pairs of screws.
Step 7. Install Chassis Rails

they lock into place. To remove the chassis rails, lift the lock
spring until it clears the pin and slide the chassis rails toward
the front of the system until the pins can slip through the
keyhole slots.
Step 8. Install the System in the Rack
1.Insert the ends of the chassis rails into the front of the rails
mounted to the rack and push the system into the rack.
2.Depending on the rail configuration, the latches on the front
of the system engage automatically.
3.If the latches do not engage automatically, secure the system
in the rack by tightening the screw under each latch.
