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 .

SFP Slots

The Small Form Factor Pluggable (SFP) transceiver slots are shared with two of the
RJ-45 ports (ports 23-24). 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 switch 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 for easy viewing, are shown below and described in the following tables.
