AS1020C-3 User's Manual
Installing the Rack Rails
Begin by joining one set of rack rails corresponding to either the left or the right side
of the rack. Do this by aligning the studs of one rail with the holes of the other rail.
Push the studs into the grooved holes and then push the rail to slide the studs to
the end of the groove. Repeat this with the rack rails used for the other side.
Next, determine where you want to place the 1020C-3 in the rack. (See Rack
and Server Precautions in Section 2-3.) Position the assembled rack rails at the
desired location in the rack. Screw the assembly securely to the rack using the
brackets provided. Attach the other assembly to the other side of the rack, making
sure both are at the exact same height and with the rail guides facing inward.
Locking Tabs: Both of the two chassis rails on each side have a locking tab (four
total), which serves two functions. The fi rst is to lock the server into place when
installed and pushed fully into the rack, which is its normal operating position.
Secondly, these tabs also lock the server in place when extended from the rack.
This prevents the server from coming completely out of the rack when you pull it
out for servicing. The two sets of locking tabs mean there are two locked positions
when the chassis is extended from the rack, allowing easy access when servicing
the system. Note that on one side, you push the locking tab up to release it and
on the other side you push it down to release.
2-4 Installing the System into a Rack
This section provides information on installing the 1020C-3 into a rack unit with the
rack rails provided. If the 1020C-3 has already been mounted into a rack, you can
skip ahead to Sections 2-5 and 2-6. There are a variety of rack units on the market,
which may mean the assembly procedure will differ slightly. You should also refer
to the installation instructions that came with the rack unit you are using.
Identifying the Sections of the Rails
You should have received a rack mounting kit with the 1020C-3. The kit includes
two sets of chassis rails (four pieces total, two of which are already installed on
the chassis) and two sets of rack rails (four pieces total). Figure 2-1 displays the
two right-side chassis rails and the two right-side rack rails. Note that two of the
four chassis rails (Chassis Rail 1) are already attached to the chassis.
