Have had a Mikrotik in our cabinet so long it is out of warranty and I am trying to bring it back to life.
Router powers on and all lights flash then no life on any ethernet port. Tried factory reset and netinstall to no avail.
Hooked a console cable up and here is the output
AL31400X-140
RouterBOOT booter 6.48.6
RB1100x4
CPU frequency: 1400 MHz
Memory size: 1024 MiB
NAND size: 128 MiB
Press any key within 2 seconds to enter setup..
loading kernel... OK
setting up elf image... OK
jumping to kernel code
Where can I get the BIOS file for this router to try a reflash over serial?
Any other suggestions?
And be careful, so you don’t loose your Licence Key, try to get it from the bootmenu.
And you can upgrade the RouterBOOT via xmodem with serial.
Havn’t seen some way for flashing the RouterOS sadly via serial.
This is the Dude version for RouterBOOT, don’t know if it the same for the old one.
And this is a very old version of the RouterBOOT.
I’d check power supplies though. A few years ago MT had a batch of bad capacitors which bulged with time (and devices started to misbehave in most strange ways). This problem affected both power supplies as well as capacitors on boards.
That model can be powered through a DC input, with a rather wide range of allowed voltage, 12-57 V, besides POE.
So it should be easy to test it with any external power supply.
But it is IMHO improbable that both internal power supplies failed (at the same time, not being powered), even if it was in the cabinet for a long time, how long was it, a couple of years?
