 The equipment rack must provide sufficient airflow to the front of the server to
maintain proper cooling. The rack must include ventilation sufficient to
exhaust a maximum of 2550 BTUs (British Thermal Units) per hour for the
NetBackup 5220 and 1270 BTUs per hour for Symantec Storage Shelf.
 The NetBackup 5220 is designed for an AC line voltage source with up to 20
amperes of overcurrent protection per cord feed. If the power system for the
equipment rack is installed on a branch circuit with more than 20 amperes of
protection, you must provide supplemental protection for the server.
Electrostatic discharge (ESD)
ESD can damage disk drives, boards, and other parts. We recommend that you
perform all procedures at an ESD workstation. If one is not available, provide
some ESD protection by wearing an antistatic wrist strap attached to chassis
ground – any unpainted metal surface -- on your server when handling parts.
Always handle boards carefully. They can be extremely sensitive to ESD. Hold
boards only by their edges. After removing a board from its protective wrapper
or from the server, place the board component side up on a grounded, static free
surface. Use a conductive foam pad if available but not the board wrapper. Do
not slide board over any surface.
Battery replacement
There is danger of explosion if the battery is incorrectly replaced. When
replacing the battery, use only the battery recommended by the
equipment manufacturer.

Dispose of batteries according to local ordinances and regulations.
 Do not attempt to recharge a battery.

Do not attempt to disassemble, puncture, or otherwise damage a
battery.
