Cisco 10008 Router Hardware Installation Guide

Chapter 3 Installing the Cisco 10008 Router
Rack-Mounting the Chassis
If you are installing the chassis on an equipment shelf, on a tabletop, or using mounting hardware other
than that supplied with the chassis, then go to the “Non-Rack Installation” section on page 3-11.
Rack-Mounting the Chassis
Rack-mounting the chassis is the preferred method of installation for the Cisco 10008 router. This
section explains how to install the rack-mount and cable-management bracket on the Cisco 10008
chassis for the following types of installations:
• Flush-Mounting in a 19-Inch Rack, page 3-3
• Center-Mounting in a 19-Inch Rack, page 3-5
• Center-Mounting in a 23-Inch Rack, page 3-7 (requires optional 23-inch bracket kit)
General Rack Installation Guidelines
When planning your rack installation, consider the following guidelines:
• The Cisco 10008 chassis requires a minimum of 13 rack units (22.3 inches or 56.6 cm) of vertical
rack space. Measure the proposed rack location before mounting the chassis in the rack.
• Before using a particular rack, check for obstructions (such as a power strip) that could impair
rack-mount installation. If a power strip does impair a rack-mount installation, remove the power
strip before installing the chassis, and then replace it after the chassis is installed.
• Allow sufficient clearance around the rack for maintenance. If the rack is mobile, you can push it
back near a wall or cabinet for normal operation and pull it out for maintenance (installing or moving
line cards, connecting cables, or replacing or upgrading components). Otherwise, allow 19 inches
(48.3 cm) of clearance to remove FRUs.
• Maintain a minimum clearance of 3 inches (7.62 cm) on the front, top, and sides of the chassis for
the cooling air inlet and exhaust ports, respectively. 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.
Caution To prevent chassis overheating, never install a Cisco 10008 router in an enclosed rack or room that is
not properly ventilated or air conditioned.
• Always install heavier equipment in the lower half of a rack to maintain a low center of gravity to
prevent the rack from falling over.
• Install and use the cable-management brackets included with the Cisco 10008 router to keep cables
organized and out of the way of the line cards and PREs. Ensure that cables from other equipment
already installed in the rack do not impair access to the cards, or require you to disconnect cables
unnecessarily to perform equipment maintenance or upgrades.
• Install rack stabilizers (if available) before you mount the chassis.
• Provide an adequate chassis ground (earth) connection for your router chassis.
In addition to the preceding guidelines, review the precautions for avoiding excessive temperature
conditions in the “Site Environmental Requirements” section on page 2-2.
