power switch, a male power outlet, and a cooling fan vent.
The figure below shows the NetScreen-5200 AC power supply.
FAN MODULES
The NetScreen-5200 has a three-fan module and the NetScreen-5400 has a two-fan
module. You can access the fan module from the left front side of each chassis.
• To remove the NetScreen-5200 fan module, turn the fan knob in the unlock
position, then gently pull the fan module lever toward you to slide the module
out.
• To remove the NetScreen-5400 fan module, loosen the two thumb screws that
secure the fan module, then gently slide the module out.
If a fan stops operating due to failure or removal, the system continues to run and
generates an alarm. When you replace the fan, do not leave the fan tray empty for more
than two minutes. See “Replacing the Fan Tray” on page 37 for more information.
