Installation Tasks
The process of installing the switch can be broken down into a series of tasks, which are described in the
following table.
DescriptionTask
Remove the switch from the packaging materials.
Save the packaging material for later use if
you need to move the chassis.
Note
Unpacking the switch
Install the switch.Installing the switch
Construct and attach a system ground wire from the
building (earth) ground to the system ground point
on the chassis.
Connecting the chassis to system ground
Power supplies that are ordered with the switch are
installed in the switch. If ordered separately, install
the power supplies. Connect the power supplies.
Installing and cabling the power supply or supplies

OL-30827-02 1

DescriptionTask
The various ports on the chassis must be connected
to the network. This process can involve only
attaching a network interface cable to the port or it
can include the installation of a transceiver of some
type in port and then attaching the network interface
cable to the transceiver.
Cabling the chassis and modules to the network
After completing the network cabling and making
sure that system ground is connected, the power
supplies can be turned on. The system powers up and
runs through a set of built-in diagnostics.

Safety Warnings

When installing or replacing the unit, the ground connection must always be made first and disconnected
last. Statement 1046
Warning
Installation of the equipment must comply with local and national electrical codes.. Statement 1074Warning
Invisible laser radiation may be emitted from disconnected fibers or connectors. Do not stare into beams
or view directly with optical instruments. Statement 1051
Warning
Before starting the installation procedures in this chapter, see the “Site Preparation Checklist”section on page
2-15 to verify that all site planning activities were completed.
Rack-Mounting Guidelines
The switch is designed to be installed in standard 19-inch racks.Note
Before rack-mounting the switch, ensure that the equipment rack complies with the following guidelines:
•The width of the rack, measured between the two front-mounting strips or rails, must be one of the
following measurements:
◦17.5 inches (44.45 cm)
◦17.75 inches (45.09 cm)
•The depth of the rack, measured between the front- and rear-mounting strips, must be at least 19.25
inches (48.9 cm).
•The rack must have sufficient vertical clearance to insert the chassis: 8.75 inches (22.23 cm) (5 RU)
Chassis height is sometimes measured in rack units (RU or just U) where 1 RU or 1 U equals 1.75 in
(44.45 mm). A typical server rack is 42 RU or 42 U in height.
Note
If the rack is on wheels, ensure that the brakes are engaged and that the rack is stabilized.Caution
Stability hazard. The rack stabilizing mechanism must be in place, or the rack must be bolted to the floor
before you slide the unit out for servicing. Failure to stabilize the rack can cause the rack to tip over.

Rack-Mounting Guidelines

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:
Warning
•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
To maintain proper air circulation through the Catalyst switch chassis, you should maintain a recommended
separation of a minimum of 6 inches (15 cm) between a wall and the chassis air intake or a wall and the
chassis air exhaust. You should also allow a minimum separation of 12 inches (30.5 cm) between the hot
air exhaust on one chassis and the air intake on another chassis. Failure to maintain adequate air space
can cause the chassis to overheat and the system to fail.
Note
Unpacking the Switch
Do not discard the shipping container when you unpack the switch. Flatten the shipping cartons and store
them with the pallet. You will need these containers if you need to move or ship the switch in the future.
Note
Check the contents of the accessory kit. Verify that you received all listed equipment, which should include
the following:
•Grounding lug and disposable ESD strap.
•Optional equipment that you ordered, such as console cables, transceivers, or special connectors.
•Blank covers are installed for the port card slots and power supply slots on the chassis.
•Rack-mount shelf kit is provided that includes brackets and a tray to support the chassis when it is
installed on a rack.
Chassis Installation Kits and Cable Guides
The chassis ships with an accessory kit, which includes chassis installation kits and cable guides:
•Standard 19-inch rack-mount L brackets (factory-installed on the chassis). Associated rack-mounting
hardware is included in the accessory kit.
•5 RU rack-mount shelf kit is included in the accessory kit.
•Two cable management guides are included in the accessory kit.

Installing the Switch Chassis
Installation Accessory Kits
The switch chassis is designed to be installed in a standard 19-inch rack, either open or enclosed. The chassis
is shipped with the 19-inch rack-mount L brackets that are factory installed on the left-front and right-front
of the chassis. Screws are included with the accessory kit that are used to secure the chassis in the rack
enclosure.
Depending on the manufacturer, the rack posts might be prethreaded to accept either 10-32 or 12-24
screws. If the rack posts are not prethreaded, you must install 10-32 or 12-24 clip nuts or cage nuts to
secure the rack-mount screws. The clip nuts or the cage nuts are not included as part of the accessory kit
and must be obtained on your own.
Note
The accessory kit also contains the following chassis installation kits:
•Rack-mount shelf kit. The rack-mount shelf kit is used to support the weight of the chassis.
•Cable guides—Two cable guides can be installed on the front of the chassis using the same sets of
screws that secure the chassis rack-mount brackets to the rack posts.
L Brackets on the Chassis
The switch chassis is shipped with two L brackets installed toward the front of each side of the chassis, as
shown in the following figure.

Installing the Rack-Mount Shelf Kit
Before installing the chassis, you should install the rack-mount shelf kit that is included as part of the accessory
kit. The rack-mount shelf kit is shipped as part of the switch accessory kit. It contains two shelf brackets, a
crossbar, and screws. The shelf brackets attach directly to the rack and help support the weight of the chassis.
Required Tools
These tools and equipment are required to install the rack-mount shelf kit:
•Number 1 and number 2 Phillips screwdrivers
•3/16-inch flat-blade screwdriver
•Tape measure and level
Installing the Shelf Brackets on a rack
On many older equipment racks, the rack posts are prethreaded to accept either 10-32 or 12-24 screws.
Newer rack enclosure posts might not be prethreaded. These rack enclosure posts require that you install
10-32 or 12-24 clip nuts or cage nuts to secure the rack-mount screws. The clip nuts or the cage nuts are
not included as part of the accessory kit and must be obtained on your own.
Note
Before you install the Shelf brackets, determine the clearance between the insides of the left and right rails
of your rack system:
•If the distance between the insides of the rails is 17.5 inches (44.45 cm), then follow the steps in .
