Chapter 2 Preparing for Installation

Electrostatic Discharge

If you will be using your switch as a PoE source, the following warning applies:

Warning Voltages that present a shock hazard can exist on inline power circuits if interconnections are made by using uninsulated exposed metal contacts, conductors, or terminals. Avoid using such interconnection methods unless the exposed metal parts are in a restricted access location and users and service people who are authorized to access the location are made aware of the hazard. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1072

This chapter describes how to prepare your site for the installation of the switch. The information is presented in these sections:

Electrostatic Discharge, page 2-2

Site Power Requirements and Heat Dissipation, page 2-4

Power Connection Guidelines for AC-Powered Systems, page 2-5

Site-Planning Checklist, page 2-16

Note See the Site-Planning Checklist at the end of this chapter to help ensure that you complete all site-planning activities before you install the switch.

Electrostatic Discharge

Electrostatic discharge is common on Category 5E and Category 6 cabling systems.

Category 5E and Category 6 cables have higher capacitance than Category 5 cables. As a result, Category 5E and Category 6 cables can store higher voltages than Category 5 cables and are more prone to damaging networking equipment if a differential discharge event occur.

Unshielded twisted-pair cables can store high voltages. When these charged cables are connected to networking equipment, energy is discharged into the networking equipment; this is known as electrostatic discharge (ESD).

Networking equipment is commonly designed and tested to withstand common mode ESD events of up to 2000 V. The design for the common mode event is based on the expectation that the discharge is delivered to all pins of a port at once.
