•
Maintain a minimum clearance of 3 inches (7.62 cm) for the front and rear of the chassis for proper
chassis cooling. Avoid placing the chassis in an overly congested rack or directly next to another
equipment rack; otherwise, the heated exhaust air from other equipment can enter the inlet air vents and
cause an overtemperature condition inside the router.
•
If rack space allows, it is recommended to leave one rack unit (1.75 inch or 4.45 cm) of vertical clearance
between the chassis and any equipment directly above it or below.
Depending on your installation and co-located equipment power dissipation, it is recommended to have
some air gap between chassis, if space allows, to reduce residual heating from one chassis to another.
Caution
•
Have the cable-management bracket (used in four places on the Cisco ASR 1013 chassis: upper half,
lower half, and left and right sides) available if you plan to install it on the front of the chassis.
•
An adequate chassis ground (earth) connection exists for your router chassis (see the Attaching a Chassis
Ground Connection, on page 388).
• Always follow proper lifting practices as outlined in the “Chassis-Lifting Guidelines” section on page
5-23 , when handling the chassis.
Attaching the Rear Rack-Mount Brackets
This section explains how to attach the rear rack-mount brackets to the chassis. Before installing the chassis
in the rack, you must install the rack-mount brackets on each side of the chassis. The forward rack-mount
brackets are already installed on the Cisco ASR 1013 chassis when it arrives at your site.
The parts and tools required for installing the rack-mount brackets and cable-management brackets are listed
in the “Tools and Equipment” section on page 5-23 .
The cable-management brackets are installed on the chassis after you install the chassis rack-mount brackets
and mount the chassis in the rack.
Note
If you are rack-mounting the chassis using the rear rack-mount brackets, then this type of installation provides
for the chassis being recessed in the rack.
To install the rear rack-mount brackets on the Cisco ASR 1013 Router, perform the following steps:
SUMMARY STEPS
1.
Locate the threaded holes on the rear side of the chassis. Make certain that you hold the rear t rack-mount
bracket with the ear and holes facing outward and towards the rear of the chassis (see the following image,
callout number 4).
2.
Position the rear rack-mount bracket top hole with the chassis second top hole from the back.
3.
Insert and tighten the screws on one side.
4.
After the bracket is secured to the side of the chassis, slide the two remaining components into the side
rack-mount bracket.
5.
Repeat Step 1 through Step 3 on the other side of the chassis. Use all the screws to secure the rear
rack-mount brackets to the chassis.
