Each port also supports auto-negotiation of flow control, so the switch can
automatically prevent port buffers from becoming saturated.
SFP SLOTS
The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of
the RJ-45 ports. 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.
