Each port also supports auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.
Note:
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.
SFP Slots
The Small Form Factor Pluggable (SFP) transceiver slots are shared with
RJ-45 ports (ports 17~18). In its default configuration, if an SFP
transceiver (purchased separately) is installed in a slot and has a valid link
on its port, the associated RJ-45 port is disabled and cannot be used. The
switch can also be configured to force the use of an RJ-45 port or SFP slot,
as required.
Note that 1000BASE-SX transceivers use multimode duplex fiber cable,
1000BASE-LX and 1000BASE-ZX transceivers use single-mode duplex
fiber cable.
Management Port
The 100BASE-TX port labeled “Mgmt” provides a dedicated management
interface which is segregated from the data traffic crossing the other ports.
This port supports auto-negotiation, so the optimum data rate and
transmission mode (10/100 Mbps at half/full duplex) can be selected
automatically, if this feature is also supported by the attached device.
However, note that the interface connection parameters of this port
cannot be configured.
