Changed line 20 from:

Older slugs have a clearly distinguishable red status LED color. Newer ones (sometime in late 2006) are not as distinguishable, it is more like orange to a darker orange.

Changed lines 18-20 from:

I have two slugs one quite a bit older than the second. While my older slug really has a clearly distinguishable red status LED color the newer one (a sticker claims production date to be 11/2006) changes from orange to a darker orange. It confused me the first time i tried to flash but depending on the light conditions the difference between the orange and "red" status can be told. Therefore the procedure to enter the upgrade mode is just the same as described above but you have to eye the status LED more carefully to get the right moment for releasing the reset button.

to:

Older slugs have a clearly distinguishable red status LED color. Newer ones (sometime in late 2006) are not as distinguishable, it is more like orange to a darker orange. If you have trouble seeing the change, the secret is to not look directly at the led; at about 45 degrees off center the contrast change is much clearer. Adjust the lighting conditions also if necessary (darker room is probably better). The procedure to enter the upgrade mode is just the same as described above though, but you have to eye the status LED more carefully to get the right reset release moment. In my case, the timing was also closer to 7 seconds rather than 10.

Failed to Enter Upgrade Mode Successfully

My slug with Unslung 6.8 beta flashes green and red(dark orange really) but is unavailable on the network. If I power down and power up normally it is available on 192.168.1.77 as usual. Anyone else experienced this? Couldn't find any logs either... (Mekondelta)

You can force the NSLU2 into "upgrade" or "assign" mode using the reset button at power-on.

  1. - Shutdown the slug
  2. - Using a paper clip, push and hold in the reset button. (The reset button is located on the back of the NSLU2 above the power connection.)
  3. - While holding in the reset button, press and release the power button.
  4. - Watch the orange Ready/Status LED and after approx 10 seconds the LED will turn solid red. Quickly release the reset button. [Edit: Well, solid red is not exact in my case, it's more a (hardly perceivable) more intense orange than at the beginning, so watch closely!]
  5. - You should be in upgrade mode which is indicated by the Ready/Status LED alternating between red and green.

The Ready/Status LED will be flashing red-green alternating for upgrade mode or flashing yellow for "assign mode". If it ends up flashing yellow, then you didn't release the reset button quickly enough after the Ready/Status LED turned red.

Addition for 2007 models!!!

With 2007 models you might (very likely) not see above mentioned colours. Apparently above mentioned procedure (if working) gets you where you otherwise get if you "telnet into Redboot", which is tricky. Once in Red(boot-loader) prompt, type "upgrade" to be able to use the Linksys FW "upgrade utility" software with a current flash image file from within Windows XP.

If the Ready/Status LED is flashing yellow rather than red/green, you didn't release the reset button quickly enough after the Ready/Status LED turned red, and the Slug is now in "assign mode", whatever that means. Don't panic; just remove the power and start again.

[pewe] I found it a lot easier to push and hold the reset button, then push the power button, and wait until the led flashes red/green. Release the reset button, and voila, use SerComm to recover your slug. (I had to use it after I accidentally installed a package with no harddisk connected.)
