Netgear RNRP4420 – READYNAS 3100 8 TB NETWORK STORAGE SYSTEM Hardware Manual

Do not let components or PCBs come into contact with your clothing, which might retain a 

charge even if you are wearing a wrist strap.

Handle a board by its edges only; do not touch its components, peripheral chips, memory 

modules, or contacts.

When handling chips or modules, avoid touching their pins.

Put the main board and peripherals back into their antistatic bags when not in use.

For grounding purposes, make sure your computer chassis provides excellent 

conductivity between the power supply, the case, the mounting fasteners and the main 
board.

After accessing the inside of the system, close the system back up and secure it to the 

rack unit with the retention screws after ensuring that all connections have been made.

Rack-Mount Precautions

Follow these rack-mount precautions:

Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with 

the full weight of the rack resting on them.

In single-rack installations, stabilizers should be attached to the rack. In multiple-rack 

installations, the racks should be coupled together.

Always make sure the rack is stable before extending a component from the rack.

You should extend only one component at a time; extending two or more simultaneously 

might cause the rack to become unstable.

Determine the placement of each component in the rack before you install the rails.

Install the heaviest components on the bottom of the rack first, and then work up.

Use a regulating uninterruptible power supply (UPS) to protect the ReadyNAS from power 

surges, and voltage spikes and to keep your system operating in case of a power failure.

Allow any hot-plug drives and power supply modules to cool before touching them.

Always keep the rack’s front door and all panels and components on the servers closed 

when not servicing to maintain proper cooling.
