Chapter 2 Preparing for Installation

General Site Requirements

•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.

Power Supply Considerations

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

Observe the following considerations:

•Check the power at the site before installing the chassis to ensure that the power is “clean” (free of spikes and noise). Install a power conditioner if necessary, to ensure proper voltages and power levels in the source voltage.

•Install proper grounding for the site to avoid damage from lightning and power surges.

•In a chassis equipped with an AC-input power supply, use the following guidelines:

–The chassis does not have a user-selectable operating range. Refer to the label on the chassis for the correct AC-input power requirement.

–Several styles of AC-input power supply cords are available; make sure you have the correct style for your site.

–Install an uninterruptible power source for your site, if possible.

–Install proper site grounding facilities to guard against damage from lightning or power surges.
