The following figure shows the two alternate mode LEDs for 5320 Series switches: SPD and STK. The
Mode button is used to cycle through three display modes for the port LEDs. In the default mode, SPD
and STK are off. SPD and STK display modes expire after 30 seconds, at which time the port LEDs
revert to the default SYS mode. Pressing and holding the Mode button initiates Bluetooth pairing.
