Each port also supports IEEE 802.3x auto-negotiation of flow control, so the
switch can automatically prevent port buffers from becoming saturated.
SFP T
RANSCEIVER
The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of
the RJ-45 ports (ports 25-28). In the default configuration, 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. The switch can also be configured to force the
use of an RJ-45 port or SFP slot, as required.
The following table shows a list of transceiver types which have been tested with
the switch. For an updated list of vendors supplying these transceivers, contact
your local SMC dealer. For information on the recommended standards for fiber
optic cabling, see "1000 Mbps Gigabit Ethernet Collision Domain" on page 60.
