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.

turn-leds-off.sh

#!/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

turn-leds-on.sh

#!/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

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

Awesome! Thank you so much!

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

Most of them are obvious, but what exactly do code 0 and 1 do? Apparently they are not used to turn the NAS on and off and they don't seem to have any effect at all. (Tested on DS220+)
