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-negotia tion, 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.
