Port State Indicators
There is one port state indicator for each of the
The following describes each indicator and the meaning of each condition:
♦Link (green)
The indicator of a port lights green when the port is connected to a pow- ered 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 (blinking green)
When information is received on a port, its indicator will blink off briefly. Upon reception, the data will be transmitted to all other connected ports.
♦Auto-partition (blinking amber)
The indicator of a port blinks amber when the port is automatically parti- tioned due to an abnormal network condition.
The hub will temporarily partition a port when too many line errors or too many collisions are detected on the port. While the segment is automati- cally partitioned, the port will be isolated from the rest of the network segment. When the problem is corrected or a valid data packet is re- ceived through the port, the port is automatically reconnected.
♦Disabled (steady amber)
The indicator of a port is orange when the port has been manually dis- abled. No packet transmission or reception can occur on the port.
