Chapter 3 Preinstallation Requirements and Planning for Cisco 1800 Series Routers (Modular)

Installation Checklist

Warning The device is designed for connection to TN and IT power systems. Statement 1007

The AC power supply includes the following features:

•Autoselects either 110 V or 220 V operation.

•All units include a 6-foot (1.8-meter) electrical power cord. (A label near the power cord indicates the correct voltage, frequency, current draw, and power dissipation for the unit.)

Site Environment

The location of your router is an extremely important consideration for proper operation. Equipment placed too close together-, or with inadequate ventilation-, or with inaccessible panels, can cause malfunctions and shutdowns, and can also make maintenance difficult. Plan for access to both front and back panels of the router.

When planning your site layout and equipment locations, remember the precautions described in the “Site Configuration” section on page 3-4to help avoid equipment failures and reduce the possibility of environmentally caused shutdowns. If you are currently experiencing shutdowns or an unusually high number of errors with your existing equipment, these precautions may help you isolate the cause of the failures and prevent future problems.

Site Configuration

The following precautions will help you plan an acceptable operating environment for your router and will help you avoid environmentally caused equipment failures:

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

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

•Make sure that the chassis cover and module back panels are secure. All empty interface card slots must have filler panels installed. The chassis is designed to allow cooling air to flow within it, through specially designed cooling slots. A chassis with uncovered openings creates air leaks, which may interrupt and reduce the flow of air across internal components.

Installation Checklist

The sample installation checklist lists items and procedures for installing a new router. Make a copy of this checklist, and mark each item when you complete it. Include a copy of the checklist for each router in your Site Log (described in the “Site Log” section on page 3-5).
