Zyxel nsa310s LEDS restored (no replies)

Today I took a closer look at the LEDs to find out if I could reactivate them.

Disk LED is working again:

Relevant changes in /etc/rc.local:

if [ -d /sys/class/leds/nsa310s:green:sys ]; then
   echo default-on  > /sys/class/leds/nsa310s:green:sys/trigger
   echo none        > /sys/class/leds/nsa310s:orange:sys/trigger
fi

if [ -d /sys/class/leds/nsa310s:green:hdd1 ]; then
   echo sata-disk  > /sys/class/leds/nsa310s:green:hdd1/trigger
fi

if [ -d /sys/class/leds/nsa310s:green:hdd2 ]; then
   echo sata-disk  > /sys/class/leds/nsa310s:green:hdd2/trigger
fi

if [ -d /sys/class/leds/nsa310s:green:usb ]; then
   echo usb-host > /sys/class/leds/nsa310s:green:usb/trigger
fi

Just in case anyone is interested (ls -lR /dev/disk/ ):
