Chapter 2 Preparing to Install Your Server 23
Operating Environment
The operating environment for the server’s rack must meet certain requirements:
• Verify that the temperature range of the rack’s location is within the limits
established for the server and all other components.
• Make certain that the rack’s location has adequate ventilation to maintain the
necessary temperature range. This is particularly important for a rack that is enclosed
in a cabinet.
• If multiple components are installed in the rack, consider additional cooling to
ensure efficient operation of the servers and other equipment.
Rack Stability
The rack must be stable and strong enough to hold the components installed.
• Check the documentation for the rack to make certain that it can carry the load of
components.
• If you are using a two-post (telco) rack, verify that the rack is securely fastened to the
building’s structure at the top and bottom.
• Make certain that all components are secured in the rack.
• When working with components in the rack, never slide out more than one unit at a
time.
Considerations for Cables
For optimal efficiency in server operation and maintenance, follow these guidelines for
handling cables connected to the server and other components in a rack.
• Install the cable-management arm supplied with the server. If you don’t install this
device, you must disconnect all cables from the server’s back panel before opening
the server in the rack.
• Arrange all component cables so that they do not interfere with access to the rack.
Ideally each component should have a cable-management option in place so that
anyone servicing units in the rack can readily determine where each cable is
connected.
• To ensure full signal strength for Ethernet, serial, and other connections, make sure
cables do not exceed established length limits.
