Installation Checklist Chapter 2 Preparing to Install the Router Site Configuration The following precautions will help you plan an acceptable operating environment for your router and help you avoid environmentally caused equipment failures: • Ensure that the room in which you operate your system has adequate air circulation. Electrical equipment generates heat. Ambient air temperature might not be able to cool equipment to acceptable operating temperatures without adequate circulation. • Always follow the ESD-prevention procedures described in the "Preventing Electrostatic Discharge Damage" section on page 2-2 to avoid damage to equipment. Damage from static discharge can cause immediate or intermittent equipment failure. • Ensure that the chassis cover is secure. The chassis is designed to allow cooling air to flow effectively inside it. An open chassis allows air leaks, which might interrupt and redirect the flow of cooling air from internal components. Equipment Racks Cisco 2600 series routers with chassis height of 1 RU can be installed in 19-, 23-, and 24-inch racks. Cisco 2600 series routers with chassis height of 2 RU can be installed in 19- or 23-inch racks. The following information will help you plan your equipment rack configuration: • Enclosed racks must have adequate ventilation. Ensure that the rack is not overly congested, because each unit generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air. • When mounting a chassis in an open rack, ensure that the rack frame does not block the intake ports or the exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated all the way into the rack. • In an enclosed rack with a ventilation fan in the top, excessive heat generated by equipment near the bottom of the rack can be drawn upward and into the intake ports of the equipment above it in the rack. Ensure that you provide adequate ventilation for equipment at the bottom of the rack. • Baffles can help to isolate exhaust air from intake air, which also helps to draw cooling air through the chassis. The best placement of the baffles depends on the airflow patterns in the rack, which can be found by experimenting with different arrangements. Installation Checklist The sample Installation Checklist lists items and procedures for installing a new router. Make a copy of this checklist and mark the entries when completed. Include a copy of the checklist for each router in your Site Log (described in the next section, "Creating a Site Log"). Cisco 2600 Series Routers Hardware Installation Guide 2-4 OL-2171-06
