SFP Slots
The Small Form Factor Pluggable (SFP) transceiver slots are shared with
four of the RJ-45 ports (ports 21~24 for the SMC8724M and ports 45~48
for the SMC8748M). 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.
Stacking Ports
Each unit includes two stacking ports that provide a 10 Gbps high-speed
serial stack backplane connection. Up to eight SMC8724M or SMC8748M
switches can be connected together using optional stacking cables. Note
that the 24-port and 48-port switches can be mixed in the same stack. The
Stack Master button enables one switch in the stack to be selected as the
Master.
