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 RJ-
45 ports (combination 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.
