The front-panel LEDs (see Figure 2) show the status of the hub and the network connections.

Figure 2 Hub LEDs

LED	Function
POWER	On	Hub is powered on

	Yellow	Traffic is 30% to 65%
	Red	Traffic is 65% or higher
COLLISION	Green	Collision rate is 1% to 10%
	Yellow	Collision rate is 10% to 15%
	Red	Collision rate is 15% or higher
PARTITION	Off	Port is operating normally
(1 through 8)	On	The port has been disconnected from the network due to exces-
		sive collisions caused by the attached computer
LINK/TRAFFIC	On	A network link is established
(1 through 8)	Blink	Data is being transmitted

Section 4 - Troubleshooting

Symptom: Partition indicator lights up.

Causes: Hub has partitioned the 100BASE-TX (RJ-45) port due to excessive collisions.

Solution: If port partitioning has occurred, the hub will automatically enable the port when the faulty condition disappears.

Symptom: Link/Traffic indicator remains unlit.

Causes: The workstation’s network adapter, cable or the hub port is defective.

Solution: The most common cause is a defective network adapter or cable connection. Check the corresponding cable connections, or the workstation’s network adapter for possible defects. Verify that the correct cable type (straight or crossover) is being used. Replace the defective cable or adapter.

Symptom: Port 8 and Daisy-Chain port do not work simultaneously. Causes: Both ports are physically the same port.

Solution: Use either Port 8 or the Daisy-chain port.
