DESCRIPTION OF
HARDWARE
1000BASE-T
PORTS
The switch contains 24 1000BASE-T RJ-45 ports. All RJ-45 ports
support automatic MDI/MDI-X operation, auto-negotiation and
IEEE 802.3x auto-negotiation of flow control, so the optimum
data rate and transmission can be selected automatically.
SFP
TRANSCEIVER
SLOTS
GS-2328KX supports the Small Form Factor Pluggable (SFP)
transceiver slots are shared with RJ-45 port 21 to 24. In the
default configuration, if an SFP transceiver (purchased
separately) 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 have
been tested with the switch. For an updated list of vendors
supplying these transceivers, contact your local dealer. For
information on the recommended standards for fiber optic
cabling, see “1000 Mbps Gigabit Ethernet Collision Domain” on
page 28.
