Chapter 2 Switch Installation

General Guidelines

Before installation, observe these general guidelines:
Proper ESD protection is required whenever you handle Cisco equipment. Installation and
Caution
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.
•
•
When determining where to place the switch, observe these guidelines:
•
•
•
•
•
When the switch is installed in an industrial enclosure, the temperature within the enclosure is greater
Caution
than normal room temperature outside the enclosure.
Ensure temperatures inside the enclosure conform to device specifications detailed in
•
If you are responsible for the application of safety-related programmable electronic systems (PES),
you need to be aware of the safety requirements in the application of the system and 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
observing boot fast. Follow the procedures in the
page 2-31.
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).
Clearance to front and rear panels meets these conditions:
Front-panel LEDs can be easily read.
–
Access to ports is sufficient for unrestricted cabling.
–
Front-panel direct current (DC) power connectors and the alarm connector are within reach of
–
the connection to the DC power source.
Airflow around the switch must be unrestricted. To prevent the switch from overheating, you must
have 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)
–
Cabling is away from sources of electrical noise, such as radios, power lines, and fluorescent
lighting fixtures.
