TPS fans
The 440T device includes five cooling fans (two of them are internal). The fans are not redundant or hot-
pluggable. If a failure to a fan module occurs, you must replace the entire device.
The 2200T device includes three cooling fans. The fans for the 2200T device are redundant but not hot-
pluggable. An individual fan can be replaced but not without first powering down the device.
The TPS Spare Fan (5066-3329) is a replacement unit and can only be used with TPS 2200T devices or
NGFW S3000/S8000 Series appliances.

critical alarm message in its logs.
You can check a fan’s performance using:
• The Local Security Manager (LSM) graphical user interface:
System Health > Monitor > Fan Speed
• The command line interface (CLI):
