INSTALLING THE ROUTER
General Site | To ensure the proper working of the routers and prolong their service life, the |
Requirements | installation site should meet the requirements described in the following sections. |
Temperature/Humidity To ensure normal operation of the Router, the equipment room must maintain Requirements temperature and humidity.
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.
Table 1 Temperature/Humidity requirements in the equipment room
Temperature | Relative humidity |
|
|
0oC to 40oC | 10% to 90% |
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 Dust is harmful to the safe operation of the Router. Dust on the chassis may result Requirements 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:
Table 2 Limitation on dust content in equipment room
Mechanical active material | Unit | Content |
|
|
|
Dust particle | particle/m³ | 3 x 104 |
(No visible dust on desk in three days) | Note: Dust particle Diameter 5µm |

|
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.
Table 3 Harmful gas limits in an equipment room
Gas | Max. (mg/m3) |
SO2 | 0.2 |
H2S | 0.006 |
NH3 | 0.05 |
