Site Requirement Guidelines

Site Requirement Guidelines

Warning This unit is intended for installation in restricted access areas. A restricted access area can be accessed only through the use of a special tool, lock and key, or other means of security. Statement 1017

The environmental monitoring functionality in the router protects the system and components from potential damage from overvoltage and overtemperature conditions. To ensure that normal operation and avoid unnecessary maintenance, plan your site configuration and prepare your site before installation. After installation, make sure the site maintains an ambient temperature of 32°F through 104°F (0°C through 40°C), and keep the area around the chassis as free from dust as is practical.

Planning a proper location for the router and the layout of your equipment rack or wiring closet is essential for successful system operation. Equipment placed too close together or inadequately ventilated can cause system overtemperature conditions. In addition, chassis panels made inaccessible by poor equipment placement can make system maintenance difficult. Following are precautions that can help avoid problems during installation and ongoing operation.

Follow these general precautions when planning your equipment locations and connections:

•Plan for access to both front and rear panels of the chassis.

•Ensure that the room where the chassis operates has adequate ventilation. Remember that electrical equipment generates heat. Ambient air temperature may not cool equipment to acceptable operating temperatures without adequate ventilation.

•Use the show environment command regularly to check the internal system status. The environmental monitor continually checks the interior chassis environment; it provides warnings for high temperature and maximum and minimum voltages and creates reports on any occurrences. If warning messages are displayed, take immediate action to identify the cause and correct the problem.

•We recommend keeping the router off the floor and out of any area that tends to collect dust.

•Follow ESD prevention procedures to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure.

•Ensure that the port adapter (or the blank port adapter) is in place and secure for proper cooling. The fans direct cooling air throughout the chassis interior; a loose component or empty slot can redirect the air flow away from active components.

Rack-Mounting Guidelines

The rack-mounting hardware included with router is suitable for standard 19-inch equipment racks and telco-type racks; brackets for 23- and 24-inch racks are available separately. To easily access the interface cables while the router is installed in a rack make certain that you have access to the rear of the router.

Before using a particular rack, check for obstructions (such as a power strip) that could impair rack-mount installation. If a power strip does impair a rear rack-mount installation, remove the power strip before installing the router in the rack, and then replace it after the chassis is installed. As an alternative, you can mount the router on an equipment shelf, provided that the rack dimensions allow you to secure the router to the shelf and the overall configuration permits safe installation and access. However, we recommend rack-mounting the router.
