SHUTDOWN LED
The S3500 is equipped with a SHUTDOWN LED (see
Figure 6
), which serves two functions:
If you execute the system halt command from the CLI or the LCD screen, the SHUTDOWN LED will
become red once the system halt is complete.
If the temperature of the S3500 exceeds the temperature threshold, the SHUTDOWN LED is lit. To check
the temperature of the chassis at anytime, scroll to the Environmental screen under Status menu on
LCD.
If any of the components of the S3500 reach the designated temperature threshold, the SHUTDOWN
LED will turn on and the S3500 will turn off to protect itself from damage. The CPU threshold is 212 ºF
(100 ºC).
Fan Tray
The S3500 is equipped with a field-replaceable, hot-swappable fan tray. Each fan tray features four
individual fans that pull air through the chassis from the front and sides through to the rear. Each fan tray
can tolerate the failure of a single fan while maintaining a safe operating temperature for the mobility
access switch.
Hot Swapping
Hot swapping allows you to replace a failed fan tray, making it unnecessary to shut down the S3500 during
the replacement procedure.

The S3500 software also sends traps to provide a warning once the system temperature approaches the system
tolerance. Additionally, you can monitor the current system status using the CLI or LCD Screen. For more
information on traps and system monitoring, see the
ArubaOS 7.1 User Guide
