Chapter 2 Preparing to Install the Router

Prerequisites

Prerequisites

Before installing the Cisco ASR 901 10G router, it is important to prepare for installation by:

•Preparing the site (site planning) and reviewing the installation plans or method of procedures (MOPs).

•Unpacking and inspecting the Cisco ASR 901 10G router.

•Gathering tools and test equipment required to properly install the Cisco ASR 901 10G router.

Site Planning

Ideally, you should have prepared the installation site beforehand. As part of your preparation, obtain a floor plan of the site and the equipment rack where the Cisco ASR 901 10G router would be housed. Determine the location of any existing routers and their interconnections, including communications and power. Following the air flow guidelines (see the “Air Flow Guidelines” section on page 2-5), ensure that adequate cooling air is provided to the router.

All personnel involved in the installation of the router including installers, engineers, and supervisors should participate in the preparation of a Method of Procedure (MOP) for approval by the customer.

Power Supply Considerations

Check the power at your site to ensure that you are receiving clean power (free of spikes and noise). Install a power conditioner if necessary (see the Power Supply, page 1-5for power requirements).

Warning This equipment is designed for connection to TN and IT power systems. Statement 16

Site Environment

Install the Cisco ASR 901 10G router in an equipment rack. The location of your router and the layout of your equipment rack, or wiring room are extremely important considerations for proper operation. Cramped equipment, inadequate ventilation, and inaccessible panels can cause malfunctions and shutdown, and can make maintenance difficult. Plan to access the front and rear panels of the router.

Take the following precautions for an acceptable operating environment for your router and to avoid environmentally caused equipment failures:

•Ensure that the room where your router operates has adequate air circulation. Electrical equipment generates heat. Without adequate circulation, ambient air temperature may not cool the equipment to acceptable operating temperatures.

•Always follow ESD-prevention procedures described in the “Preventing Electrostatic Discharge Damage” section on page 2-3to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

•The router should be placed inside a space protected from direct outside weather and environmental stress by an enclosure, where the operating climate (as defined by Class 2 of GR-3108-CORE) is between:

–-40 to +149°F (-40°C to +65°C)
