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).
