AFAIK, I am.

I assume you talk about the "Heartbeat LED" with which we blink in the
same frequency as a heart. That's also the behaviour under HP/UX.

You may see the actual values with:
pa64:~# cat /proc/pdc/led
Heartbeat: 1
Disk IO: 1
LAN Rx/Tx: 1

and change it with one of the following commands:
pa64:~# echo "0 1 1" > /proc/pdc/led
turns off only the heartbeat LED,
pa64:~# echo "0 0 0" > /proc/pdc/led
turns off all LEDs.
