Just bought one in e-Bay, plugged in everything and silent.
How do you turn it on?
After about 5 min. being plugged in - very loud fans kicked in for
about a sec. then silent again.
Opened the box, one green LED on near the IDE plug on the main board,
ON or RESET smd switchs do nothing.
Power supply is also silent (2 fans -front/back not on when plugged
in)
Would also be interested in any documentation (URL or via e-mail
(.pdf)) for the main board or device.
Regards,
Reg

Buttons located inside the top of the front door.

Flipping open the front plastic door and look at the switches. (power and reset) follow them back to the mobo. Sometimes the wires came loose or people scavenged the cards they were on so the mobo will need a new power switch.
Most Evo2s were linuxbios'ed versions of standard mobos. Examples are: the IO nodes were Rioworks HDAMA revGs (that manufacturing license has changed hands quite a few times, I lost track of who owns it now. rioworks, arima, couple others, maybe Flextronics now??) , computes were generally a Supermicro H8DCE or similar. Later boxes were straight up Dells.
If you still have a drive in it, see if it will local boot. Most were kernel-less and used multicast boot from a frontend server running Clusterworx. SGi still wants $$$ for that stuff, and it's getting REALLY long in the tooth now.
Your best bet in the long run is to re-flash the bios with something OEM unless you have a Intel networking card. It can be a real pain to get these things working with most of the other net chips as what was known as Linuxbios (now coreboot) never really finished any decent code to get these running with something modern like PXE. (mostly due to the network chipsets on the evo2s. the coreboot guys dumped linuxbios support and never finished things when they transitioned to gPXE) Though they can be multicast booted with various releases if you have an Intel network card (mostly E1s I think?) and there are quite a few folks running Evo1s with rocks clusters as it supports some cards and multicast booting linuxbios.
Good luck. There are a ton of these still out there, some still with the old software, some with more recent releases and more standard tools.

Hello Ed,
thanks for the infos.
Have unplugged/re-plugged all the plug/sockets on the board. Even the ON switch (smd ) on the main board doesn't react.
There is one LED on when plugged in, near the outer edge next to the IDE port. No power supply noise from the fans.
The very first time I plugged it in and started looking for a switch, it suddenly came to life about 5 min. after being plugged in, I was across the room at the time, and heard it start up, but only for one second, then it was quiet again. Hasn't done a thing since.
Have researched power supply options as I want to move the board into a 5U chassis so that I can use the other PCI/PCI-x slots. Will run it under Debian when I get it working.
I will test the PSU outputs to see if I can turn the power on at the board connector (short pins 16 & 17). Have exchanged the BIOS battery (orig. was 2.8V rest) with a new 3.0V, didn't help.
No ATX-GES PSUs in e-Bay in Germany at the moment. Will check other outlets.
Has no one got any tech docs for this device?
Regards,
Reg

Which motherboard is this one? I would just jumper the pin headers on the motherboard and see if it starts up. I have done this on a couple E2 nodes testing for bad switch/board in the front.
Good luck getting debian running.
Ed
Good luck getting debian running.
