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

DescriptionTask
Install the fan modules in the fan slots.Installing the fan
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
Class 1 laser product. Statement 1008Warning
This unit is intended for installation in restricted access areas. A restricted access area can be accessed
only through the use of a special tool, lock and key, or other means of security. Statement 1017
Warning
This unit might have more than one power supply connection. All connections must be removed to
de-energize the unit. Statement 1028
Warning
Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
Statement 1030
Warning
To prevent personal injury or damage to the chassis, never attempt to lift or tilt the chassis using the
handles on modules (such as power supplies, fans, or cards); these types of handles are not designed to
support the weight of the unit. Statement 1032
Warning
Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when
servicing. Statement 1034
Warning
This product requires short-circuit (overcurrent) protection, to be provided as part of the building installation.
Install only in accordance with national and local wiring regulations. Statement 1045

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
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 power supply slots on the chassis.
Establishing the System Ground
This section describes how to connect a system ground to the switch.
Installations that rely solely on system grounding using only an AC third-prong ground run a substantially
greater risk of equipment problems and data corruption than those installations that use both the AC
third-prong ground and a properly installed system ground.
Caution
The system ground provides additional grounding for EMI shielding requirements and grounding for the low
voltage supplies (DC-DC converters) on the modules. You must observe the following system grounding
guidelines for your chassis:
•You must install the system ground connection with any other rack or system power ground connections
that you make. The system ground connection is required if FXS modules are installed or if this equipment
is installed in a U.S. or European Central Office.
•You must connect both the system ground connection and the power supply ground connection to an
earth ground. The system ground connection is required if FXS modules are installed or if this equipment
is installed in a U.S. or European Central Office.
•When using DC-input power supplies, you must install the system (ground before you attach the source
DC power cables to the DC PEM. Power down the chassis before attaching the system ground.

Switch Installation
Unpacking the Switch

In all situations, grounding practices must comply with Section 250 of the National Electric Code (NEC)
requirements or local laws and regulations. An 8-24 AWG grounding wire is preferred from the chassis
to the rack ground or directly to the common bonding network (CBN). The equipment rack should also
be connected to the CBN with 8-24 AWG grounding wire.
Note
The system ground serves as the primary safety ground for chassis that are equipped with DC-input power
supplies. The DC-input power supplies for these chassis do not have a separate ground.
Note
Required Tools and Equipment
To connect the system ground, you need the following tools and materials:
•Grounding lug—A two-hole standard barrel lug. Supports up to 8-24 AWG wire. Supplied as part of
accessory kit.
•Grounding screws—Two M4 x 8 mm (metric) pan-head screws. Supplied as part of the accessory kit.
•Grounding wire—Not supplied as part of accessory kit. The grounding wire should be sized according
to local and national installation requirements. Depending on the power supply and system, a 12 AWG
to 6 AWG copper conductor is required for U.S. installations. Commercially available 8-24 AWG wire
is recommended. The length of the grounding wire depends on the proximity of the switch to proper
grounding facilities.
•No. 1 Phillips screwdriver.
•Crimping tool to crimp the grounding wire to the grounding lug.
•Wire-stripping tool to remove the insulation from the grounding wire.

Switch Installation
Required Tools and Equipment

Connecting the System Ground
To establish an earth ground for the chassis, you must attach a grounding cable from the chassis’grounding
lug to the rack.
Figure 1: Connecting the System Ground
Procedure
Step 1 Use a wire-stripping tool to remove approximately 0.75 inch (19 mm) of the covering from the end of the
grounding wire.
Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug.
Step 3 Crimp the grounding wire in the barrel of the grounding lug. Verify that the ground wire is securely attached
to the ground lug.
Step 4 Place the grounding wire lug against the grounding pad, making sure that there is solid metal-to-metal contact.
Step 5 Secure the grounding lug to the chassis with two M4 screws. Ensure that the grounding lug and the grounding
wire will not interfere with other switch hardware or rack equipment.
Step 6 Prepare the other end of the grounding wire with a ring lug, and secure it to the rack with a screw.

Connecting the System Ground

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
This figure shows the standard 19-inch brackets and other optional mounting brackets. You can order the
optional brackets from your Cisco sales representative.
