10/100/1000BASE-T Ports
The SMC8126PL2-F contains 26 RJ-45 ports that operate at 10 Mbps or 100 Mbps,
half or full duplex, or at 1000 Mbps, full duplex. Because all ports on this switch
support automatic MDI/MDI-X operation, 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-3.)
Each of these ports support auto-negotiation, so the optimum transmission mode
(half or full duplex), and data rate (10, 100, or 1000 Mbps) can be selected
automatically. If a device connected to one of these ports does not support
auto-negotiation, the communication mode of that port can be configured manually.
SFP Slots
The Small Form Factor Pluggable (SFP) transceiver slots are shared with four of the
RJ-45 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.
Port and System Status LEDs
The SMC8126PL2-F includes a display panel for key system and port indications
that simplify installation and network troubleshooting. The LEDs, which are located
on the front panel, are shown below and described in the following tables.
