Mounting the Cisco ASR 901 Router

Mounting the Cisco ASR 901 Router

Each Cisco ASR 901 router includes rack-mounting brackets. Using the rack-mounting brackets, you can front-mount theCisco ASR 901 router in a 19-inch (48.3-cm) equipment rack that conforms to the EIA-310-D specification (the inside width of the rack should be 17.72 to 17.80 inches [45 to 45.21 cm]).

Using the two rack-mounting brackets for mounting (part number 700-33522-01), you can recess Cisco ASR 901 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.

If you need to attach or replace the rack-mounting brackets, see the “Attaching the Rack-Mounting Brackets” section on page 3-3.

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 Cisco ASR 901 router requires one EIA 1.75-inch (4.4-cm) vertical mounting space (or 1 rack unit [RU]) for mounting (see the “Mounting the Cisco ASR 901 Router in a Rack” section on page 3-3).

Caution Allow clearance on either side of the Cisco ASR 901 router for cooling air to be drawn in through the left side and circulated through the chassis and out the two fan exhaust ports mounted on the other side of the chassis.

Rack-Mounting Configuration Guidelines

Follow these guidelines to configure the equipment rack:

•When mounting the router to an equipment rack, ensure that the rack is bolted to the floor.

•Because you may install more than one router into the rack, ensure that the weight of all of the routers installed does not make the rack unstable.

Caution Some equipment racks are also secured to ceiling brackets, if necessary, due to the weight of the equipment in the rack. Make sure that the rack you are using to install the routers is secured to the building structure.

•As mentioned in the “Air Flow Guidelines” section on page 2-5, maintain a 6-inch (15.24-cm) clearance on each side of the router to ensure adequate air intake and exhaust.

•Avoid installing the routers in an overly congested rack. Air flowing to or from other routers in the rack might interfere with the normal flow of cooling air through the routers, increasing the potential for overtemperature conditions within the routers.

•Allow at least 19 inches (48.7 cm) of clearance at the front and rear of the rack for router maintenance.

•Follow your local practices for cable management. Ensure that cables to and from the routers do not impede access to perform equipment maintenance or upgrades.
