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:

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,

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
Damage" section on page 2-2
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.
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.
