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 Table 1-3.
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.
