♦ Collision Indicators (10M/100M) These LEDs indicate data
collisions on the respective 10Mbps Ethernet or 100Mbps Fast
Ethernet segments connected to the hub. (If several hubs are linked
together, all of them should detect and indicate the same collision,
since collisions span the entire network segment.) Whenever a
collision is detected, the respective collision indicator will briefly
blink amber.
♦ Link (steady green) This LED will be lit when the port is
connected to a powered Ethernet or Fast Ethernet station. If the
station to which the hub is connected is powered off, or if there is a
problem with the link, the LED will remain off.
♦ Receive (Rx) (blinking green) When information is received
on a port, its LED indicator will blink off briefly. Upon reception, the
data will be transmitted to all other connected ports.
♦ 10/100 Port Speed Indicators
There is a port speed LED
indicator for each of the twisted-pair ports on the hub. A port speed
indicator will light green when a 100BASE-TX device is connected to
the port. It will remain dark if the port is not connected or if a
10BASE-T device is connected.

♦ Twisted-Pair Ports Use any of these ports to connect stations
to the hub. The ports are MDI-X ports, which means you can use
ordinary straight-through twisted-pair cables to connect the hub to
PCs, workstations, or servers through these ports. If you need to
connect another device with MDI-X ports such as another hub or an
Ethernet switch, you should use a crossover cable, or connect using
the Uplink port.
♦ Uplink Port The Uplink port is an MDI-II port, which means
you can connect the hub to another device with MDI-X ports using an
ordinary straight-through cable, making a crossover cable
unnecessary. Port 1 and the Uplink port are really the same port,
