DESCRIPTION OF HARDWARE
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.
Table 1-1 Optional SFP Transceivers
1000BASE-SX (SMCBGSLCX1)
1000BASE-LX (SMCBGLLCX1)
1000BASE-ZX (SMCBGZLCX1)
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.
