During the installation, wear an ESD (Electro-Static Discharge) preventive wrist 
strap and ESD-preventive gloves. See “Static Electricity” on page 20 for 
additional information on ESD prevention.

3Com recommends that you use an uninterrupted power supply (UPS) with your 
router.

The environment of the installation site influences the performance and lifetime of 
the router. The installation site for your router should meet the following 
requirements for temperature and humidity, dust, gases, static electricity, and 
electromagnetic discharge.

To ensure normal operation and to prolong the operational lifetime of the router, 
the temperature and humidity of the equipment room must be within controlled 
limits. The requirements for the temperature and humidity of the router 
installation site are listed in Table 22. 

Table 22   Temperature and Humidity Requirements

Dust is harmful to the safe operation of the router. The specifications for the dust 
content and diameter of the granule within the equipment room are listed in 
Table 23.

Table 23   Specification for Dust Content

The equipment room of the router must meet strict requirements for the content 
of salt, acid and sulfide. The specific limitation values of these harmful gases are 
given in Table 24.

Table 24   Harmful Gas Limitation Values in Equipment Room

To prevent damage caused by the static electricity, insure that:
