Cisco XR 12410 Router Installation Guide

To help maintain trouble-free operation, adhere to the following precautions when
planning your rack installation:
Ensure the site of the rack includes provisions for source AC or DC power,
•
grounding, and network interface cables.
Allow sufficient space to work around the rack during the installation. You
•
need:
At least 3 feet adjacent to the rack to move, align, and insert the chassis.
–
At least 2 feet in front of the power shelf to insert power entry modules.
–
Maintain at least 24 inches (61 cm) of clearance in front of and behind the
•
chassis for maintenance after installation.
To mount the router between two posts or rails, the usable aperture (the width
•
between the inner edges of the two mounting flanges) must be at least
17.7 inches (45.0 cm).
The height of the router is 37.0 inches (93.98 cm). Most racks accommodate
•
two routers.
When fully populated with cards, the router can weigh as much as 275 lb
•
(124.74 kg). To maintain equipment rack stability and to ensure your safety,
the rack is provided with stabilizing devices. Make sure you install the
stabilizers before installing the router.
If you use a telco-style rack, the weight of the chassis is cantilevered off of
•
the two rack posts. Make sure that:
The weight of the router does not make the frame unstable.
–
The frame is bolted to the floor and is secured to the building structure
–
using either wall brackets or overhead brackets.
When mounting the router in a telco-type rack or 4-post rack, be sure to use
•
all of the screws provided to secure the chassis to the rack posts.
Install the cable-management brackets included with the router to keep cables
•
organized. Be sure to:
Use appropriate strain-relief methods to protect cables and equipment
–
connections.
Make sure that cables from other equipment installed in the rack do not
–
restrict access to the card cages.
