Cisco Systems 3120 Manual De Usuario

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 AVS 3120.

Always follow the ESD-prevention procedures described in the 

 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.

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. Statement 1017

Follow these guidelines when choosing a site for installation:

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

Choose a site that maintains an ambient temperature of 0° to 40°C 
(32° to 104°F).

The AVS 3120 relies on the protective devices in the building installation for protection against 
short-circuit, overcurrent, and earth (grounding) fault. Ensure that the protective devices in the building 
installation are properly rated to protect the AVS 3120, and that they comply with national and local 
codes.

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the 
absence of a suitably installed ground conductor. Contact the appropriate electrical inspection 
authority or an electrician if you are uncertain that suitable grounding is available. Statement 1024
