INSTALLING THE ROUTER

General Site

Requirements

To ensure the proper working of the routers and prolong their service life, the

installation site should meet the requirements described in the following sections.

Temperature/Humidity

Requirements

To ensure normal operation of the Router, the equipment room must maintain

temperature and humidity. Long-lasting moisture can degrade the performance of

the insulating material, which may result in electric leakage, leading to metal

erosion. The following table lists the requirements of 3Com Router 6000 in

temperature and humidity.

The values of the operating temperature and humidity in router equipment refers

to the values measured at the position 1.5m above the floor and 0.4m ahead of

the router rack; given there are no protective boards in front or at the back of the

router rack.

Cleanliness

Requirements

Dust is harmful to the safe operation of the Router. Dust on the chassis may result

in static absorption, and causes poor contact of the metal connection components

or points.

There should not be explosive, conductive, magnetic, or corrosive dust in the

equipment room where 3Com 6000 Routers are located, and the dust

concentration should meet the following requirements:

Besides the dust specifications, the equipment room of the Router should also

meet the rigorous requirements for the content of salt, acid and sulfide. These

harmful gases could accelerate the metal erosion and the aging process of some

parts. The specific limits of these harmful gases are given in the following table.
