Trellix recommends reviewing the electrical and general safety precautions that came with each component you intend to install in the rack.
Review the following before installing the appliance in the rack:
Determine the placement of each component in the rack.
Ensure there is a minimum clearance of six inches behind the chassis to allow for easy cable management.
Install the heaviest component at the bottom of the rack first, then move up.
Allow hot-swappable power supply units, disk drives, and transceivers to cool before handling them.
Use a regulating uninterruptible power supply to protect your components from voltage spikes, power surges, and failure during a power outage.
Keep all of the rack's doors and panels closed when you are not servicing the components.
