Description of Hardware
1000BASE-T Ports
These ports are 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, 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.
Each port also supports IEEE 802.3x auto-negotiation of flow control, so
the switch can automatically prevent port buffers from becoming
saturated.
SFP Slots
The Small Form Factor Pluggable (SFP) transceiver slots are shared with
four of the RJ-45 ports (Ports 9~12). 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.
