Notes: Each combo SFP port on the G3G124-24, G3G124-24P or G3G-24TX 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 10/100/1000 base systems or the G3G-24TX module

eliminates the availability of one RJ45 port. In other words, only 24 ports can be active at any given

time on components equipped with a combination of RJ45 and SFP interfaces. When an SFP

transceiver (Mini-GBIC) SFP port 23 establishes a link, RJ45 port 23 is disabled. When an SFP

transceiver (Mini-GBIC) in SFP port 24 establishes a link, RJ45 port 24 is disabled.
