This red-green flashing probably means that it is indeed in the "upgrade mode"
See
http://www.nslu2-linux.org/wiki/HowTo/UseTheResetButtonToEnterUpgradeModeSo you could re-flash using either "upslug2" utility or the Sercom, "upgrade" tool
See
http://www.nslu2-linux.org/wiki/HowTo/RecoverFromABadFlashHowever you may just be able to hard-power-cycle (i.e. unplug and then reconnect the DC jack)
and the slug will typically revert back to your previous ("unslung"?) firmware
(well that it what it has done when I tried this)
Note that it *may* have reverted to the default fixed IP address of 192.168.1.77 rather than DHCP-assigned
So you could try changing your PC's IP config to access it
But you really ought to try searching the www.nslu2-linux.org project Wiki before asking on this forum because it provides answers to loads of the standard issues/problems that people have with their slugs.

Subject: [nslu2-linux] red and green light flashing on NSLU2
I wanted to flash my NSLU2 device with the original Linksys firmware, so I went to the Administration Upgrade Mode thinking I could flash the device with the old firmware. Now I do not have access to the network storage device and the light is alternately flashing red and green. I may have made a mistake in trying to reset the device as well.
Is it possible to recover from this mode? I have no idea what the IP address would be now for the device. I do not want to deal with JTAG and all. Is all hope lost and I should just recycle this device?
Thank you.
