Do not place any object on top of rack-mounted devices.
Site Environment
The location of your server and the layout of your equipment rack or wiring room
are important considerations for proper operation. Equipment placed too close
together, inadequate ventilation, and inaccessible panels can cause malfunctions
and shutdowns, and can make maintenance difficult. Plan for access to the
server front and rear panels.
are important considerations for proper operation. Equipment placed too close
together, inadequate ventilation, and inaccessible panels can cause malfunctions
and shutdowns, and can make maintenance difficult. Plan for access to the
server front and rear panels.
The following precautions will help you plan an acceptable operating
environment for your server and will help you avoid environmentally caused
equipment failures:
environment for your server and will help you avoid environmentally caused
equipment failures:
Ensure that the room where your server operates has adequate circulation.
Electrical equipment generates heat. Without adequate circulation, ambient
air temperature may not cool equipment to acceptable operating
temperatures. See

Ensure the site of the rack includes provisions for source AC power,
grounding, and network cables.
Allow sufficient space to work around the rack during the installation. You
need:
a) At least 3 feet (9.14 m) adjacent to the rack to move, align, and insert
the serv.
b) At least 24 inches (61 cm) of clearance in front of and behind the
server for maintenance after installation.
To mount the server 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).
17.7 inches (45.0 cm).
Use appropriate strain-relief methods to protect cables and equipment
connections.
To avoid noise interference in network interface cables, do not route them
directly across or along power cables.
from static discharge can cause immediate or intermittent equipment failure.
Airflow Guidelines
Warning! Blank faceplates and cover panels serve three important functions:
they prevent exposure to hazardous voltages and currents inside the chassis;
they contain electromagnetic interference (EMI) that might disrupt other
equipment; and they direct the flow of cooling air through the chassis. Do not
operate the system unless all cards, faceplates, front covers, and rear covers are
in place. Statement 1029

To ensure adequate airflow through the equipment rack, it is recommended that
you maintain a clearance of at least 6 inches (15.24 cm) at the front and the rear
of the rack.
