Description of Hardware
RJ-45 Ports
The switch base unit contains 16 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.
Status LEDs
The LEDs, which are located on the front panel for easy viewing, are
shown below and described in the following table.
