Rack Stability
The rack must be strong enough to hold the installed components.
• Ensure that the leveling jacks at the bottom of the rack are fully extended and are secure.
• If using a two-post (telco) rack, be sure that the rack is securely fastened to the building at
the top and the bottom.
• In single rack installations, stabilizers should be attached to the rack.
• When working with components in the rack, never slide out more than one unit at a time.
Cables
For optimal efficiency in server operation and ease of maintenance, handling cables properly is
required.
• Arrange all component cables so they do not interfere with access to the rack.
• To ensure full signal strength for Ethernet, serial, and other connections, make sure the
cables do not exceed established length limits.
Security
The following are security considerations:
• If using a server cabinet that is not in a secure room, be sure the cabinet is adequately locked
and access is limited to authorized staff.
• Control access to the server environment with a plan for distributing and controlling keys
and access information.
• Store a copy of server access information at a safe location away from the server site.
