General Site Requirements
Warning Ultimate disposal of this product should be handled according to all national
laws and regulations. (To see translated versions of this warning, refer to the appendix
“Translated Safety Warnings.”)
Site Environment
The location of individual 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, keep in mind 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
currently 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
multiport serial 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
“Safety Recommendations” earlier in this chapter to avoid damage to equipment.
Damage from static discharge can cause immediate or intermittent equipment failure.
• Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to
flow effectively within it. An open chassis allows air leaks, which may interrupt and
redirect the flow of cooling air from internal components.
