General Installation Guidelines
Observing the following precautions can prevent injuries, equipment failures, and
shutdowns:
„ Never assume that the power supply is disconnected from a power source.
Always check first.
„ Room temperature might not be sufficient to keep equipment at acceptable
temperatures without an additional circulation system. Ensure that the room in
which you operate the NetScreen-5000 Series has adequate air circulation.
„ Do not work alone if potentially hazardous conditions exist.
„ Look carefully for possible hazards in your work area, such as moist floors,
ungrounded power extension cables, frayed power cords, and missing safety
grounds.
