Each of these ports support auto-negotiation, so the optimum
transmission mode (half or full duplex), and data rate (10 or 100 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.
Each port also supports auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.
SFP Slots
The TL-SL5428 contains four Small Form Factor Pluggable (SFP)
transceiver slots that are shared with four associated 1000BASE-T RJ-45
ports. If an SFP transceiver (purchased separately) is installed in a slot and
has a valid link on the 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 TL-SL5428 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.
