Preparing for Controller Installation

To ensure proper airflow it is necessary to rack the controllers using rail kits. Physically placing the units
on top of one another or “stacking”without the use of the rail kits blocks the air vents on top of the
controllers, which could result in overheating, higher fan speeds, and higher power consumption. We
recommend that you mount your controllers on rail kits when you are installing them into the rack because
these rails provide the minimal spacing required between the controllers. No additional spacing between
the controllers is required when you mount the units using rail kits.
The rail mounting kit (Part Number: UCSC-RAILB-M4=) is provided along with the Cisco 5520 WLC
and you do not have to order it separately.
Caution
Avoid UPS models that use ferroresonant technology. These UPS models can become unstable with
systems such as the Cisco UCS, which can have substantial current draw fluctuations from fluctuating
data traffic patterns.
Caution
Rack Requirements
This section provides the requirements for the standard open racks.
The rack must be of the following type:
•A standard 19-in. (48.3-cm) wide, four-post EIA rack, with mounting posts that conform to English
universal hole spacing, per section 1 of ANSI/EIA-310-D-1992.
•The rack post holes can be square 0.38-inch (9.6 mm), round 0.28-inch (7.1 mm), #12-24 UNC, or
#10-32 UNC when you use the supplied slide rails.
•The minimum vertical rack space per controller must be one RU, equal to 1.75 in. (44.45 mm).
Equipment Requirements

Rack Requirements

To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions
to ensure that the system remains stable. The following guidelines are provided to ensure your safety:This
unit should be mounted at the bottom of the rack if it is the only unit in the rack.When mounting this unit
in a partially filled rack, load the rack from the bottom to the top with the heaviest component at the bottom
of the rack.If the rack is provided with stabilizing devices, install the stabilizers before mounting or
servicing the unit in the rack. Statement 1006
Warning
Step 1 Attach the inner rails to the sides of the controller:
a) Align an inner rail with one side of the controller so that the three keyed slots in the rail align with the three pegs on
the side of the controller (see Attaching Inner Rail to Side of Controller).
b) Set the keyed slots over the pegs, and then slide the rail toward the front to lock it in place on the pegs. The front slot
has a metal clip that locks over the front peg.
c) Install the second inner rail to the opposite side of the controller.

Step 2 Open the front securing plate on both slide-rail assemblies. The front end of the slide-rail assembly has a spring-loaded
securing plate that must be open before you can insert the mounting pegs into the rack-post holes (see Front Securing
Mechanism, Inside of Front End).

Step 3 Install the outer slide rails into the rack:
a) Align one slide-rail assembly front end with the front rack-post holes that you want to use.
The slide rail front-end wraps around the outside of the rack post and the mounting pegs enter the rack-post holes
from the outside-front (see Front Securing Mechanism, Inside of Front End).
The rack post must be between the mounting pegs and the open securing
plate.
Note
b) Push the mounting pegs into the rack-post holes from the outside-front.
c) Press the securing plate release button, marked PUSH. The spring-loaded securing plate closes to lock the pegs in
place.
d) Adjust the slide-rail length, and then push the rear mounting pegs into the corresponding rear rack-post holes. The
slide rail must be level front-to-rear.
The rear mounting pegs enter the rear rack-post holes from the inside of the rack post.
e) Attach the second slide-rail assembly to the opposite side of the rack. Ensure that the two slide-rail assemblies are
at the same height with each other and are level front-to-back.
f) Pull the inner slide rails on each assembly out toward the rack front until they hit the internal stops and lock in place.
Step 4 Insert the controller into the slide rails:
This controller can weigh up to 67 pounds (59 kilograms) when fully loaded with components. We recommend
that you use a minimum of two people or a mechanical lift when lifting the controller. Attempting this
procedure alone could result in personal injury or equipment damage.
Caution
a) Align the rear of the inner rails that are attached to the controller sides with the front ends of the empty slide rails on
the rack.
b) Push the inner rails into the slide rails on the rack until they stop at the internal stops.

Step 5 (Optional) Secure the controller in the rack more permanently by using the two screws that are provided with the slide
rails. Perform this step if you plan to move the rack with controller installed.
With the controller fully pushed into the slide rails, open a hinged slam latch lever on the front of the controller and
insert the screw through the hole that is under the lever. The screw threads into the static part of the rail on the rack post
and prevents the controller from being pulled out. Repeat for the opposite slam latch.
Installing the Cable Management Arm (Optional)
Step 1 With the controller pushed fully into the rack, slide the CMA tab of the CMA arm that is farthest from the controller
onto the end of the stationary slide rail that is attached to the rack post (see Attaching the Cable Management Arm to the
Rear of the Slide Rails). Slide the tab over the end of the rail until it clicks and locks.
The CMA is reversible left to right. To reverse the CMA, see Reversing the Cable Management Arm (Optional)
before installation.
