Site Selection Guidelines
The Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router require specific environmental
operating conditions. Temperature, humidity, altitude, and vibration can affect the performance and reliability
of the router. The following sections provide specific information to help you plan for the proper operating
environment.
The Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router are designed to meet the industry
EMC, safety, and environmental standards described in the Regulatory Compliance and Safety Information
for the Cisco ASR 920 Series Router document.
Environmental Requirements
Environmental monitoring of the Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router
protects the system and components from damage caused by excessive voltage and temperature conditions.
To ensure normal operation and avoid unnecessary maintenance, plan and prepare your site configuration
before installation. After installation, make sure that the site maintains the environmental characteristics
described in
Cisco ASR 920-24SZ-IM, ASR-920-24SZ-M, ASR-920-24TZ-M Router Specifications
table.
For an outside plant installation (cell site cabinet, hut etc.), it is required that the Cisco ASR 920-24SZ-IM,
ASR-920-24SZ-M, ASR-920-24TZ-M Router be protected against airborne contaminants, dust, moisture,
insects, pests, corrosive gases, polluted air or other reactive elements present in the outside air. To achieve
this level of protection, we recommend that the unit be installed in a fully sealed enclosure or cabinet. Examples
of such cabinets include IP65 cabinets with heat exchanger complying with Telecordia GR487. Temperature
must be maintained within
–
40º C to 70º C.
The equipment shall be placed inside a space protected from direct outside weather and environmental stresses
by an enclosure, and where the operating climate, as defined by Class 2 of GR-3108-CORE, is between
•
-40°C (-40°F) and 70°C (158°F)
•
5 and 85% RH
