Jetway JNC9C-550-LF resume after power fail

Just putting this out there in hopes that saves someone else some time…

Way too long ago, I set out to rebuild into an even lower-power configuration.  Today it uses about 40W, and I picked out some parts which got it idling at about 18W.  But due to lack of time, and timidity about migrating from RHEL5 to RHEL6 I still haven’t migrated.  I put a couple Maple Crest SSDs in for the root fs, and now I think I’m finally on my way, but one sticking point was that I was unable to find the BIOS setting to get the box to turn itself back on again after a power failure.  (I do have a UPS, but if that gets exhausted, I want to come back when the power does!).

Anyway, here’s how you do it:

  1. Under “Power Management” disable the “EUP function”
  2. Under “Integrated Peripherals” change “PWR status after PWR Failure” to “Always On”

This had me stumped for a while; I knew I had to disable “EUP” (a European directive for pushing down power consumption of  devices like this, something I generally applaud.  Shipping power-savings by default makes good sense, but I have a different use case.)

So when disabling it, I did get options like “Wake by PCI” and “Wake by Ring” (For everyone running a BBS?!) but nothing about power state after power fail/resume.  Why this is under “Integrated Peripherals” I have no idea, but if you happened to be looking for it, hopefully this helped you out.  ;)

Update: Apparently this isn’t unique to Jetway boards.  Rik had a similar problem; on his board it was the “ERP” function (not EUP) but the resume setting was also under “Integrated Peripherals” – go figure!

  1. Thank you! I was starting to go crazy trying to figure out how to do that get it to power on (I chose “resume state” in case I power it off for an electrical storm or something).

  2. Thanks man… I’m throwing together a pfSense box based on a Jetway NF9D-2700 motherboard. The applicable setting was ERP for me.

  3. Our company uses Jetway motherboards in a range of products; your post saved us time and money. It’s incredible how poorly American Megtrends laid this out in the BIOS. They could at least have greyed out, or even simply placed the power-up option inside the ERP subsection instead of essentially showing a nonfunctional option.

    Thanks Eric!

  4. You are my hero. after hours of searching for this I googled and came across your post. THANK YOU! Why they made it so you have to do a ritual sacrifice to find that setting… I have no idea!

  5. Mate. I have been sat here nearly crying trying to figure this. Going to their website directly is gut wrenchingly slow. Manuals seem not to mention it at all.

    So following your method (having a Jetway JNC9C-550-LF board) i have the ERP option set to disabled to yeild more power options. After coming out of there, the option IS in the integrated peripherals!!

    If i knew your hygiene status i could kiss you ;-)

      • I’ll certainly do that next time i’m looking to order something!
        Trying to get the thing to PXE boot now. Fails each time. The bios says boot from network on the first two options, and the SSD on the last.
        Prompts twice for the network config after initial bios (shift+F10) each set to PXE boot. And yet still doesn’t boot off the network.
        Oh well, it’ll be around somewhere :-)

        Thanks again fella! :-D

  6. WOW! Thank you! Didn’t tested yes, but was driving me crazy! We are using a NF99FL, powered on batteries, and couldn’t make it boot.

    I hope this could help. Thx!

  7. Thanks! I know this is an older thread, but I’ve been using one of these for VPN access to our PBX (located off site) and I kept having to call the tech down there every time the power went out and ask him to fire it back up.

  8. Thanks, this helped me alot!
    Because a lack of time I was even thinking about connecting a timer relay to the on/off switch :P
    In my case the “PWR status after PWR Failure” to “Always On” was in the same (Power Managment) menu.
