LOTS
The 12 Small Form Factor Pluggable (SFP) transceiver slots are shared with 12
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.
The SFP slots support the following SFP transceivers:
1000 Mbps Ethernet SFP transceivers
◆
1000BASE-LX5
■
1000BASE-LX15
■
1000BASE-LHX
■
1000BASE-ZX
■
100 Mbps Ethernet SFP transceivers
◆
100BASE-FX

10/100/1000BASE-T P
The switch contains contains 12 1000BASE-T RJ-45 ports that operate at 10
Mbps or 100 Mbps, half or full duplex, or at 1000 Mbps, full duplex. Because all
of the RJ-45 ports 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
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.
