NETGEAR DS108 - Verify the Installation; Cable and Connector Information

Model DS108 Dual Speed Hub Installation Giude
When installation is complete and power has been applied to the hub, the following conditions
should exist:
• Power LED is on.
• Link LED on each connected port is on.
• Utilization LEDs on the front panel are blinking when data is being received by any port in
the hub, and the Link/Receive LED on the connected port is blinking when data is being
received by that port.
If there are any problems, refer to the Troubleshooting table.
Twisted Pair Cables
For two devices to communicate, the transmitter of each device must be connected to the receiver
of the other device. The crossover function is usually implemented internally as part of the
circuitry in the device. Most hub and switch ports are MDI-X wired and called normal ports.
Computers and workstation adapter cards are usually MDI wired and called uplink ports.
An uplink port connects to a normal port using standard straight-through cable, and a normal port
connects to a normal port using a crossover cable.
The figures illustrate the use of straight-through and crossover twisted pair cables.
