Amber — The download was interrupted before it was completed.
On a LAN, the download process is completed quickly. If the
download from NCP to digital line card must travel a routed
network path, the download may take a few minutes. If the DNLD
light remains amber, it can indicate a severely congested network
or a hardware problem with the card.

to an external LAN hub or switch. You can use this connector to
isolate E1 traffic. If the E1 Digital Line Card is used in a V5000
Gateway Chassis, do not use this connector because the chassis has
an Ethernet connector to connect the chassis to the LAN.
