It really doesn't believe the cable's plugged in. The LED's might just be hardwired. mii-tool talks with the transceiver itself, so it's the one I'd trust... Very strange that it autonegotiated a 100baseT link with a 1000baseT peer.
Have you tried a normal cable, not a crossover cable? I've sometimes experienced odd behavior with ports capable of autodetecting the cable type. You might also try forcing the speed and duplex, gigabit links often have problems negotiating -- though if you've discovered a gigabit interface that's incapable of negotiating with itself that's certainly something new!
Hi all,
Is there any difference between a null modem cable or a modem cable ?
i assume that a null modem cable is a normal cable that i used from cpu serial ports to a modem for dialup.
please correct if i am wrong,

LIEBERT(8) NUT Manual LIEBERT(8)NAME
liebert - Driver for Liebert contact-closure UPS equipment
NOTE
This man page only documents the hardware-specific features of the liebert driver. For information about the core driver, see nutupsdrv(8).
SUPPORTED HARDWARE
This driver supports some Liebert UPS equipment with a contact-closure interface. This includes the UPStation GXT2 with their
contact-closure cable. The smart mode ("Multilink") cable is not supported by this driver.
EXTRA ARGUMENTS
This driver does not support any extra settings in the ups.conf(5).
BUGS
This driver does not yet support shutdowns by raising DTR. Be aware that shutdowns are not possible with the stock contact-closure cable.
You may have to build another cable with DTR connected through to the UPS for it to work.
There is no way for this driver to detect the hardware or cable. It will start up successfully even if no UPS is present. This is a
fundamental limitation of any contact-closure driver.
