Installation and Configuration
WARNING: Before performing the following procedure, review and follow the
safety instructions that came with the system.
Installing the Tool-Less Rail Solution
WARNING: Whenever you need to lift the system, get others to assist you.
To avoid injury, do not attempt to lift the system by yourself.
WARNING: The system is not fixed to the rack or mounted on the rails. To
avoid personal injury or damage to the system, you must adequately
support the system during installation and removal.
WARNING: To avoid a potential electrical shock hazard, a third wire safety
grounding conductor is necessary for the rack installation. The rack
equipment must provide sufficient airflow to the system to maintain proper
cooling.
CAUTION: When installing rails in a square-hole rack it is important to
ensure that the square peg slides through the square holes.
