Observing the following precautions can prevent injuries, equipment failures and
shutdowns.
• Never assume that the device 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 device 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.
• The product should be installed in a restricted area to prevent personal injury
from exposure to DC voltage.

NetScreen-50 device in a locked-room environment.
