Preparing for Installation
Equipment Rack Guidelines
The placement of the rack can affect personnel safety, system maintenance, and the system's ability to operate
within the environmental characteristics described in the Cisco NCS 560-4 Routers Datasheet. Choose a proper
location for the Cisco NCS 560-4 Router by following the guidelines listed below.
Locating for Safety
If the Cisco NCS 560-4 Router is the heaviest or the only piece of equipment in the rack, consider installing
it at or near the bottom to ensure that the rack's center of gravity is as low as possible.
For additional information about the proper placement of electronic equipment, consult the document
GR-63-CORE, Network Equipment Building System (NEBS) Requirements: Physical Protection.
Locating for Easy Maintenance
Keep at least three feet (36 inches) of clear space at the front and two feet (24 inches) at the back of the rack.
This space ensures that you can remove the Cisco NCS 560-4 Router components and perform routine
maintenance and upgrades easily.
Avoid installing the Cisco NCS 560-4 Router in a congested rack and consider how routing of cables from
other pieces of equipment in the same rack could affect access to the router cards.
The sides of the chassis must remain unobstructed to ensure adequate airflow and prevent overheating inside
the chassis.
Allow the following clearances for normal system maintenance:
• At the top of the chassis—At least 3 inches (7.6 cm)
• Sides of the chassis—3 to 4 ft (91.44 cm to 121.92 cm)
To avoid problems during installation and ongoing operations, follow these general precautions when you
plan equipment locations and connections:
• Use the show environment all command regularly to check the internal system status. The environmental
• Keep the Cisco NCS 560-4 Router off the floor and out of areas that collect dust.
• Follow ESD-prevention procedures to avoid damage to equipment. Damage from static discharge can
Locating for Proper Airflow
Ensure that the Cisco NCS 560-4 Router location has enough airflow to keep the system operating within the
environmental characteristics and the air temperature is sufficient to compensate for the heat dissipated by
the system.
Note
If you are installing the chassis in a plenum, the air flow direction changes from
right-to-left of router to front-to-back of the router. In this case, the side space is
not required.
monitor continually checks the interior chassis environment; it provides warnings about high temperature
and creates reports on other potentially dangerous occurrences. If warning messages are displayed, take
immediate action to identify the cause, and correct the problem.
cause immediate or intermittent equipment failure.
