Any thoughts or concerns?
Assuming that you have two different switches (because you don't have a Single Point Of Failure SPOF in your network setup) you may unplug one cable without any harm. If you unplug the cable that is used by the Service Label an adapter swap (or an etherchannel failover) will occur that should be transparent for the application. Wait till the swap took place before you reconnect. If you unplug the cable that is stand-by you will see an event in the logs only.

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.

SEE ALSO

   The core driver:
       nutupsdrv(8)
