Hi guys,
I had to turn off my very old (but still functional) Lacie Network space v1 (white case) because of some sort of rearrangement in my workplace. After that I wasn't able to start it on again. The blue led light is flashing, I can hear disc spinning for about 10 seconds and after that it stops and is complety unusable. I cannot connect to it, I cannot ping it - nothing. It is not the disc fault. I can connect it to pc using any sata adapter and I can see all partitions etc.

So I decided to open my Lacie and eximine the pcb inside. The capasitors were in a bad shape so I solder new ones. It is still non functional. Than I noticed that two components on the pcb are very hot. So I think there is a short ciruit.

There is no boardview online. So can you guys help me to identify these two components?
I think that first one is marked as "C84" and second is some kind of controller marked as "IC9". I will try to read the markings printed on it but they are very small and barely visible.



Can somebody be so kind and help me? :please

I have an internet space v1 and it sometimes doesn't boot with similar behavior as you describe. I leave it connected for a while with power on and then try again a power off/on after 15 minutes, then most of the times it boots. About the components you mention. These are smd components which are very difficult (impossible) to replace and even if you are able to read the id then still you will need a component list to see what exactly the component is.

What you could do is connect to the serial port to see if the bootloader is active and tries to load the system
Also you could try to connect with the fvdw-sl console and use uboot console available in the fvdw-sl console

First of all I'm sorry for very long delay. I was able to buy portable lcd digital microscope I read the smd markings:
K47
187
But I'm still unable to identify this component.

I tried to leave it connected for half an hour and then power off and on again - nothing,
fvdw-sl console cannot find it,
serial port connection - no luck.

Right now I'm out of options :(

serial port connection - no luck.

Did you try to use it or do you not know how to connect.
If you do not get output on serial console then my conclusion is that your ns1 is dead. Smd is almost impossible to replace. Maybe you can find another nis1 on ebay or better a network space v2

I do not know how to connect to the serial port.
I think pcb is not dead because even network leds are blinking but I was not able to find this device in my network.

Blinking led of ethernet connector can also be caused by your router or network switch. Anyhow to check if your internet space is dead or not you will need to connect to the serial port. This can be done using a usb->232 TTL 3.3 volt serial connector cable. I must have somewhere a picture from serual connector on internet space 1. I will post when I have found it

I found have a picture of internet space 1 serial connector
I used a nokia-ca42 cable (cut of the phone plug plug and connect some cables, see picture)

The gray cable is TX (pin 8), the green cable = RX (pin(7) and the blue GND (pin 2) (with this nokia cable no need to connect 3.3V (pin 1))

Ok. I've got FT232 usb. I was able to connect via serial port (serial port speed should be set up to 115200). Look at this:

Flash is corrupted?

I am not at home right now, uboot seems to be loading, so no flash not corrupt. Are you able to get a marvell>> prompt (stop autoboot)
If so we can do several actions to check your board

Yes I was able to stop autoboot and get marvell prompt. Tomorrow I'm going to install new 2Tb drive so we can try to install new system. Thank you for your support.
