SFP Slots
The Small Form Factor Pluggable (SFP) transceiver slots are shared with
four of the RJ-45 ports (ports 21-24 for the SMC8824M and ports 45-48
for the SMC8848M). 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.
10 Gigabit Ethernet Module Slots
These switches include two slots on the rear panel for hot-swappable
single-port 10GBASE modules with XFP transceivers. Refer to “Optional
Media Extender Module” on page 1-8 for more information on this
module and the supported 10G transceivers.
Stacking Ports
Each unit includes two stacking ports that provide a 48 Gbps high-speed
serial stack backplane connection. Up to eight SMC8824M or SMC8848M
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 unit for managing the entire stack.
