Installing The Router In A Rack - Cisco ASR 920 Series Installing Manual

Installing the Router in a Rack

Installing the Router in a Rack
Each Cisco ASR 920 Series Aggregation Services Router router includes rack-mounting brackets. Using the
rack-mounting brackets, you can mount the router in a 19-inch, 23-inch, or an ETSI rack that conforms to the
EIA-310-D specification.
Using the two rack-mounting brackets for mounting, you can recess the router in the equipment rack. This
arrangement provides extra space in front of the router for the cables and allows you to close the doors of
racks equipped with front-close doors.
To attach or replace the rack-mounting brackets, see the Attaching Brackets to the Router section.
The rack-mounting brackets are slotted to allow the router to be mounted in racks with EIA 1.25-inch (3.175-cm)
or WECO 1.0-inch (2.54-cm) hole spacing. When installed in the rack, the router requires one EIA 1.75-inch
(4.4-cm) vertical mounting space (or 1 rack unit [RU]) for mounting (see the Mounting the Router in a Rack
section).
Caution Allow clearance on either side of the router for cooling air to be drawn in through the right side and circulated
through the chassis and out the three-fan exhaust ports mounted on the other side of chassis.
The sections describe how to install the router in a rack. The procedures in this section apply to both horizontal
and vertical mounting of the router in a rack:

The bracket orientation and the brackets that you use depend on whether you are attaching the brackets for a
19-inch, 23-inch, or an ETSI rack. The following figure shows the types of mounting brackets.
