Fan Modules; Netscreen-5000 Modules - Juniper NetScreen-5000 Series Installation And Configuration Manual

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.
If a fan stops operating due to failure or removal, then 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 Module" on page 48 for more
information.
