maintenance personnel should be properly grounded by using ground straps to eliminate the risk of
ESD damage to the switch.
Do not touch connectors or pins on component boards. Do not touch circuit components inside the
switch. When not in use, store the equipment in appropriate static-safe packaging.

Cisco IE 3000 Switch Hardware Installation Guide
B-6
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.
The equipment should be mounted in a suitable enclosure rated to at least IP54 as defined in
EN60529 and Pollution Degree 2 as defined in IEC 60664-1 and used within their rated electrical
and environmental ratings.
Provision should be made, either in the apparatus or external to the apparatus, to prevent the rated
voltage from being exceeded by transient disturbances of more than 40 percent.
Make sure that all connectors and caps are securely tightened to properly seal the connections
against leaks and to maintain IP enclosure-type requirements.
Personnel responsible for the application of safety-related programmable electronic systems (PES)
shall be aware of the safety requirements in the application of the system and shall be trained in
using the system.
This product is grounded through the DIN rail to chassis ground. Use zinc-plated yellow-chromate
steel DIN rail to assure proper grounding. The use of other DIN rail materials (such as aluminum,
plastic, and so on) that can corrode, oxidize, or are poor conductors can result in improper or
intermittent grounding. Secure the DIN rail to the mounting surface approximately every 7.8 in. (200
mm), and use end-anchors appropriately.
Before installing the switch, first verify that the switch is operational by powering it on and running
POST. Follow the procedures in the
For 10/100 ports and 10/100/1000 ports, the cable length from a switch to an attached device cannot
exceed 328 feet (100 meters).
For 100BASE-FX fiber-optic ports, the cable length from a switch to an attached device cannot
exceed 6562 ft (2 km).
Operating environment is within the ranges listed in
