Description of Hardware
10BASE-T/100BASE-TX Ports
These are dual-speed RJ-45 ports. 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“100BASE-TX/10BASE-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 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 IEEE 802.3x auto-negotiation of flow control, so
the switch can automatically prevent port buffers from becoming
saturated.
1000BASE-T/SFP Ports
These are combo Gigabit RJ-45 ports with shared Small Form Factor
Pluggable (SFP) transceiver slots. 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.
The 1000BASE-T RJ-45 ports support automatic MDI/MDI-X operation,
so 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-4.)
