LED Description
Per-port Link • Green – indicates that the port hardware detects a cable plugged
into the port and a good link is established.
• Red (intermittent) – indicates that the port received an error
during operation.
• Red (solid) – indicates that the port hardware detects a cable
plugged into the port, however, a bad link is established.
• Off – indicates that no link from exists with the port.
Per-port Rx • Green – indicates when the port’s transceiver receives packets.
• Orange – indicates when the port’s transceiver receives flow-
control packets.
Per-port Tx • Green – indicates when the port’s transceiver transmits packets.
• Orange – indicates when the port’s transceiver transmits flow-
