The following is a brief description of each element on the faceplate.
Enable/Disable Switch
This switch is used to disable the card prior to insertion or removal from
the network shelf. While this switch is in disable position, the card will not
respond to the system CPU.
ENET LEDs
Two red LEDs indicate if the "ENET0" and "ENET1" portions of the card are
disabled. These LEDs are lit in the following cases:
