The DockStar cannot be put into failsafe mode by pressing the button.

It can however be put in failsafe mode using serial console and pressing 'f' and <enter> when prompted during boot-up

The DockStar's only button is not configurable and inevitably performs a hard reset when pressed, the button open the bridge between the positive pole and the power cord.

There are no screws - the bottom cover is held by ten plastic snap on clips, three on the sides and two on the edges. To open the case, gently pry all around with a thin screwdriver until it is open.

The serial pins are accessible without further disassembly.

How to connect to the Serial Port of this specific device:

Connect device to Ethernet port. To prevent automatic updates by cloud engines (which may disable ssh access), use a separate switch or disconnect your router from the internet. If the ssh access was disabled by the automatic cloud engine update service, you need to login there and re-activate ssh.

Find IP address, BE and EF are the last two bytes of the MAC of your device (printed on the bottom of the Dockstar)

root@host ~ # ifconfig eth0 
root@host ~ # nmap -e eth0 -sP $(printf "169.254.%d.%d" 0xbe 0xef)

Connect to IP address via ssh (root / stxadmin) to see if it works.

Finding the IP address did not work on my device, but i managed to get it this way: root@host ~ tcpdump -s 1500 -n -l -w - -i $MYETHERNET dst | strings Hello there. I am at Time is 1356445289 and I am hungry.Hostname:<>.CPU:<armv5tejl>.Distribution:<hipserv2_seagateplug>.Status:<0> 4Hello there.

If you want to restore the original firmware at a later point use this guide to make a backup. You need to login to the original firmware via ssh first. Another method beside using “dd” is nanddump. To be on the safe side, you should take a 2nd backup with the nanddump method. Assuming you have a USB Stick or other USB drive mapped via sda - you can try this:

cd /tmp
mkdir backup
mount /dev/sda1 /tmp/backup
chmod +x nanddump
./nanddump -nf backup/mtd0 /dev/mtd0
./nanddump -nf backup/mtd1 /dev/mtd1
./nanddump -nf backup/mtd2 /dev/mtd2
umount /dev/sda1
