Installing the Server In a Rack
d. Pull the inner slide rails on each assembly out toward the rack front until they hit the internal stops
and lock in place.
Step2 Insert the server into the slide rails (see Figure2-3):
Caution This server weighs approximately 86 pounds (39 kilograms) when fully loaded with components. We
recommend that you use a minimum of two people when lifting the server. Attempting this procedure
alone could result in personal injury or equipment damage.
Note The inner rails are preattached to the sides of the server at the factory. You can order replacement
inner rails if these are damaged or lost (Cisco PID UCSC-RAIL-2U-I).
a. Align the inner rails that are attached to the server sides with the front ends of the empty slide rails.
b. Push the server into the slide rails until it stops at the internal stops.
c. Push in the slide rail locking clip (item 2) on each inner rail, and then continue pushing the server
into the rack until its front flanges latch onto the rack posts.

Step3 Attach the (optional) cable management arm (CMA) to the rear of the slide rails (see Figure 2-4):
Note The CMA is reversible left to right so that you can attach it to either slide rail.
a. With the server pushed fully into the rack, insert the CMA tab that is labeled OUTER RAIL (items
1 and 6) into the clip inside the rear of the outer slide rail. Insert the tab into the clip until it clicks
and locks.
b. Pull outward on the spring-loaded peg that is on the CMA tab that is labeled INNER RAIL (items 2
and 5). You can turn this peg 90 degrees to lock it in the open position.
