General Site Requirements

General Site Requirements
The topics in this section describe the requirements your site must meet for safe installation and
operation of your system. Ensure that your site is properly prepared before beginning installation.
This section includes the following topics:
•
•
•
•

Site Environment

Place the chassis on a desktop or mount it on a rack. The location of the chassis and the layout of the
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 the chassis maintenance difficult.
For information on physical specifications, see table 7 at the following url:

When planning the site layout and equipment locations, keep in mind the precautions described in the
next section
possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or
unusually high error rates 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 plan an acceptable operating environment for the chassis and avoid
environmentally caused equipment failures:

Power Supply Considerations

For information on power supply considerations including environmental operating ranges and power
requirements, see table 7 at the following url:

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 previously to avoid damage to equipment.
Damage from static discharge can cause immediate or intermittent equipment failure.
Ensure that the chassis top panel 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 the internal components.
