Shock and Vibration Requirements

The switch has been shock- and vibration-tested for operating ranges, handling, and earthquake standards.

Grounding Requirements

The switch is sensitive to variations in voltage that is supplied by the power sources. Overvoltage, undervoltage,
and transients (or spikes) can erase data from memory or cause components to fail. To protect against these
types of problems, ensure that there is an earth-ground connection for the switch. You can connect the grounding
pad on the switch either directly to the earth-ground connection or to a fully bonded and grounded rack.
When you properly install the chassis in a grounded rack, the switch is grounded because it has a metal-to-metal
connection to the rack. Alternatively, you can ground the chassis by using a customer-supplied grounding
cable that meets your local and national installation requirements. For U.S. installations, we recommend
6-AWG wire. Connect your grounding cable to the chassis with a grounding lug (provided in the switch
accessory kit) and to the facility ground.
Note You automatically ground AC power supplies when you connect them to AC power sources. For DC power
supplies, you must connect a grounding wire when wiring the power supply to the DC power source.

Rack and Cabinet Requirements

You can install the following types of racks or cabinets for your switch:
• Standard perforated cabinets
• Solid-walled cabinets with a roof fan tray (bottom-to-top cooling)
• Standard open four-post Telco racks
Work with your cabinet vendors to determine which of their cabinets meet the following requirements or see
the Cisco Technical Assistance Center (TAC) for recommendations:
• Use a standard 19-inch (48.3-cm), four-post Electronic Industries Alliance (EIA) cabinet or rack with
• The depth of a four-post rack must be 24 to 32 inches (61.0 to 81.3 cm) between the front and rear
Also, you must have power receptacles that are located within reach of the power cords that are used with the
switch.
mounting rails that conform to English universal hole spacing per section 1 of the ANSI/EIA-310-D-1992
standard.
mounting rails (for proper mounting of the bottom-support brackets or other mounting hardware).
