Publication date: Feb., 2012Revision A14DESCRIPTION OFHARDWARE1000BASE-TPORTSThe switch contains 24 1000BASE-T RJ-45 ports. All RJ-45 portssupport automatic MDI/MDI-X operation, auto-negotiation andIEEE 802.3x auto-negotiation of flow control, so the optimumdata rate and transmission can be selected automatically.SFPTRANSCEIVERSLOTSGS-2328KX supports the Small Form Factor Pluggable (SFP)transceiver slots are shared with RJ-45 port 21 to 24. In thedefault configuration, if an SFP transceiver (purchasedseparately) is installed in a slot and has a valid link on the port,the associated RJ-45 port is disabled.The following table shows a list of transceiver types which havebeen tested with the switch. For an updated list of vendorssupplying these transceivers, contact your local dealer.
