Environmental Requirements

3Com X Family Hardware Installation Guide #15

Environmental Requirements

In order for the 3Com X Family device to run properly, your environment must meet the proper

criteria.

The following table lists the recommendations for temperature, humidity, and altitude settings for the

Service Provider (SP) environment.

System Grounding Requirements

Damage from electrotatic discharge (ESD) can occur when electronic components are improperly

handled. This damage can result in complete or intermittent system failures. Proper ESD protection is

required whenever you handle equipment. It is not necessary to open the chassis to add or remove any

components. The unit has no replaceable parts inside it.

WARNING: Read all of the installation instructions before you connect the system

to its power source.

Never touch uninsulated telephone wires or terminals unless the telephone line

has been disconnected at the network interface.

Do not operate the system unless all faceplates and covers are in place.

Faceplates and cover panels serve three important functions: They prevent

exposure to hazardous voltages and currents inside the chassis; they contain

electromagnetic interference (EMI) that could disrupt other equipment; and they

direct the flow of cooling air through the chassis.

To prevent personal injury or damage to the chassis, lift the chassis from beneath

its lower edge.

For rack-mountable equipment, enclosed racks may have higher ambient

temperatures than open racks. Ensure that enclosed racks’ ambient temperatures

do not exceed maximum recommended ambient temperature of 104

F (40

C).
