Description of Hardware
RJ-45 Ports
The switch base unit contains 24 10BASE-T / 100BASE-TX RJ-45 ports.
All of these 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 "10BASE-T/100BASE-TX Pin
Assignments" on page B-2)
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 this feature is also supported by the attached
device. If a device connected to one of these ports does not support
auto-negotiation, the correct speed will be sensed by the port, but the
transmission mode will default to half duplex.
Each port also supports auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.
