Turn leds on/off on Synology DiskStation

Synology scheduled tasks

Usage

Go to Control Panel / Task Scheduler and add the content of these scripts as root scripts.

Leds

Codes have been taken from this article.

  • turn-leds-off.sh: turns leds off
  • turn-leds-on.sh: turn leds back on

Ex (this is how I use it): turn leds daily at 10PM, turn them back on at 6AM.

#!/bin/sh
printf \\x36 > /dev/ttyS1 # UART2_CMD_LED_POWER_OFF
printf \\x37 > /dev/ttyS1 # UART2_CMD_LED_HD_OFF
printf \\x42 > /dev/ttyS1 # UART2_CMD_LED_USB_OFF
printf \\x4B > /dev/ttyS1 # UART2_CMD_LED_10G_LAN_OFF
printf \\x50 > /dev/ttyS1 # UART2_CMD_LED_MIRROR_OFF
#!/bin/sh
printf \\x34 > /dev/ttyS1 # UART2_CMD_LED_POWER_ON
printf \\x38 > /dev/ttyS1 # UART2_CMD_LED_HD_GS
printf \\x40 > /dev/ttyS1 # UART2_CMD_LED_USB_ON
printf \\x4A > /dev/ttyS1 # UART2_CMD_LED_10G_LAN_ON
printf \\x51 > /dev/ttyS1 # UART2_CMD_LED_MIRROR_GS

Turns off my Power and status light, but not LAN or USB. DSM 6.0, DS216j

Hey Guys, thanks for the script, I really appreciate it... I've just found that in DSM there is actually a feature now to completely control the LEDs. It's under 'Control Panel>Hardware & Power>LED Brightness Control' it allows you to completely turn off the LEDs and to set a schedule too... Hopefully this helps someone. Cheers

The setting "LED Brightness Control" does not exist on my NAS. (DS1515+; DSM 6.0.2-8451 Update 9).
Does nobody has a solution for LAN LED?

I have the RS3617xs with DSM 6.1.3-15152 Update 1 and the LED options within control panel do not exist. I used the script trick with the DS1515+ but once I updated that system to DSM 6.0 it no longer worked. I tried the script with my RS3617xs but only the power button goes out, not the insanely bright HDD lights.

Has anybody tried that with a extension unit? In my case a DX513. Cause the main module has a led control via the website but I seem to be unable to find the settings for the extension...

For me only Power, Status and USB works on DS211+ :(
The option to control the LED from Synology itself is only avaiable on newer devices. (DS916+ in my case).

Is there a way also to switch off LAN, DISC1 and DISC2? That would be great for me :)

Thanks for this, like some of the people it works for power LEDs etc but not for disk activity LEDs.

Does anyone know the codes to turn off the LAN, DISC1 and DISC2 lights too?

Thanks

Thanks for this. The blue power LED was driving me nuts (ds3617xs).

Function code working from Task scheduler script on the DSM or from SSH:

echo 0 >/dev/ttyS1 Power on
echo 1 >/dev/ttyS1 Power off
echo 2 >/dev/ttyS1 Short beep
echo 3 >/dev/ttyS1 Long beep
echo 4 >/dev/ttyS1 Power LED on
echo 5 >/dev/ttyS1 Power LED flash
echo 6 >/dev/ttyS1 Power LED off
echo 7 >/dev/ttyS1 Status LED off
echo 8 >/dev/ttyS1 Status LED on green
echo 9 >/dev/ttyS1 Status LED flash green
echo A >/dev/ttyS1 USBCopy LED flash
echo B >/dev/ttyS1 USBCopy LED off
echo C >/dev/ttyS1 Reset
echo @ >/dev/ttyS1 USBCopy LED on
echo : >/dev/ttyS1 Status LED on orange
echo ; >/dev/ttyS1 Status LED flash orange

You can mix several code together.

echo 48 >/dev/ttyS1 Power LED on + Status LED on green
