2-4 Router Installation and Configuration Guide
General Site Requirements
Caution For safety, periodically check the resistance value of the antistatic strap, which
should be between 1 to 10 megohms (Mohms).
General Site Requirements
This section describes the requirements your site must meet for safe installation and
operation of your system. Ensure that your site is properly prepared before beginning
installation.
Site Environment
The router can be placed on a desktop or mounted in a rack or on a wall. The location of
the chassis and the layout of your equipment rack or wiring room are extremely important
for proper system operation. Equipment placed too close together, inadequate ventilation,
and inaccessible panels can cause system malfunctions and shutdowns, and can make
system maintenance difficult.
When planning your site layout and equipment locations, remember the precautions
described in the next section, “Preventive Site Configuration” to help avoid equipment
failures and reduce the possibility of environmentally caused shutdowns. If you are
experiencing shutdowns or unusually high errors with your existing equipment, these
precautions may help you isolate the cause of failures and prevent future problems.
Preventive Site Configuration
The following precautions will help you plan an acceptable operating environment for your
router and will help you avoid environmentally caused equipment failures.
•
Electrical equipment generates heat. Ambient air temperature might not be adequate to
cool equipment to acceptable operating temperatures without adequate circulation.
Ensure that the room in which you operate your system has adequate air circulation.
•
Always follow the ESD-prevention procedures described in the section “Preventing
Electrostatic Discharge Damage” earlier in this chapter to avoid damage to equipment.
Damage from static discharge can cause immediate or intermittent equipment failure.
