Cascade Devices to the Hub

If you need more ports, connect a crossover port on another device to the Uplink port on the hub with straight-through

twisted-pair cable, maximum 5 meters (16.4 ft.). Note that if you are using the Uplink port you cannot use the fixed crossover port on port 4.

1. Prepare staight-through Category 5 twisted-pair cable with RJ-45 plugs.

Make sure the cable does not exceed 5 meters (16.4 feet).

2. Connect one end of the cable to the hub’s uplink port. When using the Uplink Port be sure not to use Port 4.

3.Connect the other end of the cable to an MDI-X RJ-45 port on the other device (not an MDI port).

•Alternatively, you can connect from any MDI-X port on the hub to an MDI daisy-chain port on the other device.

•You may also attach to MDI-X ports at both ends if you use crossover cabling.

•When connecting to another 100Mbps Fast Ethernet hub, the number of cascaded hubs is limited to two, and the total network span allowed is only 205 meters (672 feet).

Verify System Operation

Check each connection by viewing the port status indicators shown in the following table. The hub monitors the link status for each port. If the Port indicator fails to light when you connect a device to the hub, follow the troubleshooting advice

detailed in the next section.

Port and Hub Status LEDs

LEDs	Condition	Status
Power	Green	Hub is receiving power.
Collision 100	Flashing	Indicates that a packet collision has been
	green	detected on the 100Mbps segment.
Collision 10	Flashing	Indicates that a packet collision has been
	green	detected on the 10Mbps segment.
Port 1 ~ 4	Green	Port has established a valid 100Mbps
		network connection.
	Yellow	Port has established a valid 10Mbps
		network connection.
	Flashing	Traffic is traversing the port.
Memory Error	Yellow	Indicates the hub has failed its power-on
