SFP Slots<br />
DESCRIPTION OF HARDWARE<br />
Each port also supports auto-negotiation of flow control, so the switch<br />
can automatically prevent port buffers from becoming saturated.<br />
Note: If an SFP transceiver (purchased separately) is installed in a slot and<br />
has a valid link on the port, the associated RJ-45 port is disabled.<br />
The Small Form Factor Pluggable (SFP) transceiver slots are shared with<br />
RJ-45 ports (ports 17~18). In its default configuration, if an SFP<br />
transceiver (purchased separately) is installed in a slot and has a valid link<br />
on its port, the associated RJ-45 port is disabled and cannot be used. The<br />
switch can also be configured to force the use of an RJ-45 port or SFP slot,<br />
as required.<br />
Note that 1000BASE-SX transceivers use multimode duplex fiber cable,<br />
1000BASE-LX and 1000BASE-ZX transceivers use single-mode duplex<br />
fiber cable.<br />

The 100BASE-TX port labeled “Mgmt” provides a dedicated management<br />
interface which is segregated from the data traffic crossing the other ports.<br />
This port supports auto-negotiation, so the optimum data rate and<br />
transmission mode (10/100 Mbps at half/full duplex) can be selected<br />
automatically, if this feature is also supported by the attached device.<br />
However, note that the interface connection parameters of this port<br />
cannot be configured.<br />
