A while ago I got a Synology and I noticed that my baby is attracted by its blue LED button in particular and the blinking lights, resulting in pushing the power button multiple times etc.... Yes, I know, I should put the box out of his reach, and I thought I did...
Then, i looked on the internet if there's any way to turn some of the lights off (ideally the HDD lights) and I found a wiki page. The idea is that you need a command line shell to the Synology box and you and do all kind of funny things with
echo <character> >/dev/ttyS1
From the page:
|4||0x34||Power LED on|
|5||0x35||Power LED blink|
|6||0x36||Power LED off||*|
|7||0x37||Status LED off||*|
|8||0x38||Status LED green on|
|9||0x39||Status LED green blink|
|:||0x3A||Status LED orange on|
|;||0x3B||Status LED orange blink|
|@||0x40||Copy LED on||*|
|A||0x41||Copy LED blink|
|B||0x42||Copy LED off||*|
Note: These settings get reset on reboot so, if you want to repeat them, you'd better use a script stored directly on the server.
