Combo ports are ports individually configurable to be 10/100/1000Base-T or 1000Base-X, which
support SFP transceivers for short, long and very long distances.
Gigabit fiber interfaces on the OmniSwitch 6855-U10 and OmniSwitch 6855-U24 support Gigabit
SFP or 100Base-X SFP optical transceivers. See the full list of supported transceivers at the end
of the data sheet.
Power supplies
All OmniSwitch 6855 models support redundant,
hot-swappable AC, DC or PoE power supplies.
The primary as well as the back up power supply units are external which allows for easier
maintenance and replacement.
There is no interruption of service when a new power supply is installed or an old one replaced.
