Description of Hardware
10BASE-T/100BASE-TX Ports
There are eight fixed 10/100BASE-TX RJ-45 ports on the switch. Because
these ports 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.
Each of these ports support auto-negotiation, so the optimum
transmission mode (half or full duplex) and data rate (10/100 Mbps)
can be selected automatically. Each port also supports IEEE 802.3x
auto-negotiation of flow control, so the switch can automatically
prevent port buffers from becoming saturated.
Note:
If a device connected to one of these ports does not support
auto-negotiation, the communication mode of that port can be
configured manually.
1000BASE-T Port
There is one fixed 1000BASE-T RJ-45 port on the switch’s front
panel. This port operates at 10, 100 or 1000 Mbps, and supports
auto-negotiation of speed, duplex mode (i.e., half or full duplex), and
flow control.
This port is shared with the Gigabit Module slot on the switch’s rear
panel. If a 1000BASE-X module is installed in the slot and has a
valid link on its port, the 1000BASE-T port is disabled.
Note:
If an attached device does not support auto-negotiation, you will
have to manually configure the switch and the other device to
match the duplex mode and speed.
