Notes:
Each combo SFP port on the D2G124-12 and D2G124-12P supports the installation of
Mini-GBICs for 1000Base-SX, 1000Base-LX, 100Base-FX or 1000Base-T copper SFP
transceivers.
Each combo SFP port in use on these units eliminates the availability of one RJ45 port. In other
words, only twelve ports can be active at any given time. When an SFP transceiver (Mini-GBIC)
SFP port 11 establishes a link, RJ45 port 11 is disabled. When an SFP transceiver (Mini-GBIC) in
SFP port 12 establishes a link, RJ45 port 12 is disabled.
Note:
The D2-PWR supply will power either the D2G124-12 or the D2G124-12P without PoE
support. The D2-PWR-POE is the only supply for powering the D2G124-12P with PoE support.
