Dual-Speed Stackable Hubs User's Guide Port State Indicators There is one port state indicator for each of the twisted-pair ports on the hub. Each port LED status indicator reports the port link and activity status, and shows whether or not the port has been partitioned. 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 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 (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 partitioned 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 automatically partitioned, the port will be isolated from the rest of the network segment. When the problem is corrected or a valid data packet is received through the port, the port is automatically reconnected. ♦ Disabled (steady amber) The indicator of a port is orange when the port has been manually disabled. No packet transmission or reception can occur on the port. 18 Understanding Indicators
