In addition to the status lights on the PCI card cage, there are eight status lights located on the U522 PCI card itself. These status lights show activity on the Ethernet network. There is a pair of green and yellow lights above and below the four RJ-45 cable connectors. The yellow LNK (link) light indicates the card is connected to the network and is receiving link pulses. The green ACT (activity) light indicates activity on the network.
