Preparing for Installation
Caution Airflow around the switch must be unrestricted. To prevent the switch from overheating, there must be
the following minimum clearances:
– Top and bottom: 2.0 in. (50.8 mm)
– Sides: 2.0 in. (50.8 mm)
– Front: 2.0 in. (50.8 mm)
Contact your Cisco Technical Assistance Centre (TAC) if tighter spacings are required.

When determining where to place the switch, observe these guidelines.
Environment and Enclosure Guidelines
Review these environmental and enclosure guidelines before installation:
• This equipment is intended for use in a Pollution Degree 2 industrial environment, in overvoltage
Category II applications (as defined in IEC publication 60664-1), at altitudes up to 9842 ft (3 km)
without derating.
• This equipment is considered Group 1, Class A industrial equipment, according to IEC/CISPR
Publication 11. Without appropriate precautions, there may be potential difficulties ensuring
electromagnetic compatibility in other environments due to conducted as well as radiated
disturbance.
• This equipment is supplied as open-type equipment. It must be mounted within an enclosure that is
suitably designed for those specific environmental conditions that will be present and appropriately
designed to prevent personal injury resulting from accessibility to live parts. The enclosure must
have suitable flame-retardant properties to prevent or minimize the spread of flame, complying with
a flame-spread rating of 5VA, V2, V1, V0 (or equivalent) if nonmetallic. The interior of the
enclosure must be accessible only by the use of a tool. Subsequent sections of this publication might
contain additional information regarding specific enclosure-type ratings that are required to comply
with certain product safety certifications.
