Chapter 2 Preparing for Installation

Preparing Your Site for Installation

Environmental

When planning your site layout and equipment locations, remember the precautions described in this section 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 will help you isolate the cause of failures and prevent future problems.

Use the following precautions when planning the operating environment for your GSS.

Always follow the ESD-prevention procedures described in the “Protecting Against Electrostatic Discharge”section to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

Make sure that the chassis cover is secure. The chassis allows cooling air to flow effectively within it. An open chassis allows air leaks, which could interrupt and redirect the flow of cooling air from internal components.

Electrical equipment generates heat. Ambient air temperature might not be adequate to cool equipment to acceptable operating temperatures without adequate circulation. Make sure that the room in which you operate has adequate air circulation.

Choosing a Site for Installation

Warning This unit is intended for installation in restricted access areas. A restricted access area is where access can only be gained by service personnel through the use of a special tool, lock and key, or other means of security, and is controlled by the authority responsible for the location.

Choose a site with a dry, clean, well-ventilated and air-conditioned area.

Choose a site that maintains an ambient temperature of 10° to 35°C (50° to 95°F).
