Installation Checklist
•
Ensure that the chassis cover and module rear panels are secure. All empty network module slots,
interface card slots, and power supply bays 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 permits air leaks, which may interrupt and reduce the flow of air across internal
components.
Equipment Racks
Cisco IAD2801 series integrated access devices include brackets for use with a 19-inch rack.
Note
Brackets for a 23-inch rack are not available for Cisco IAD2801 series integrated access devices.
The following information will help you plan your equipment rack configuration:
•
Allow clearance around the rack for maintenance.
•
Allow at least one rack unit of vertical space between routers.
•
Enclosed racks must have adequate ventilation. Ensure that the rack is not congested, because each
router generates heat. An enclosed rack should have louvered sides and a fan to provide cooling air.
Heat generated by equipment near the bottom of the rack can be drawn upward into the intake ports
of the equipment above.
•
When mounting a chassis in an open rack, ensure that the rack frame does not block the intake or
exhaust ports. If the chassis is installed on slides, check the position of the chassis when it is seated
into 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 configurations.
•
When equipment installed in a rack (particularly in an enclosed rack) fails, try operating the
equipment by itself, if possible. Power off other equipment in the rack (and in adjacent racks) to
allow the router under test a maximum of cooling air and clean power.
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, “
