Prerequisites
Before installing the router, it is important to prepare for the installation by:
•
Preparing the site (site planning) and reviewing the installation plans or method of procedures (MOP).
See Site Planning section.
•
Unpacking and inspecting the router. See Chassis-Lifting Guidelines section.
•
Gathering the tools and test equipment required to properly install the router. See Tools and Equipment
section.
For more instructions on how to prepare for the installation of the router, see Preparing for Installation section.
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).
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.
Caution
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:
