1000BASE-T/SFP Ports
The SMC6248M contains two combination Gigabit RJ-45 ports that are
shared with Small Form Factor Pluggable (SFP) transceiver slots (Ports
49-50, Figure 1-1 on page 1-2). If an SFP transceiver (purchased separately)
is installed in a slot, the associated RJ-45 port is disabled. The switch can be
configured to force the use of an RJ-45 port or SFP slot, as required.
The 1000BASE-T RJ-45 ports support automatic MDI/MDI-X operation,
so you can use straight-through cables for all network connections to PCs or
servers, or to other switches or hubs. (See “1000BASE-T Pin Assignments”
on page B-5.)
Stacking Ports
The unit provides two stacking ports that provide a 4 Gbps stack backplane
connection. Up to four switches can be connected together using Category 5
Ethernet cables (purchased separately). The Master button enables one
switch in the stack to be selected as the master. This is the unit through
which you manage the entire stack.
The stacking ports can also be used as normal Ethernet ports in standalone
mode by pressing the Uplink button.
