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 system CPU.

Port Out of Service LEDs

Two red LEDs indicate if the "ENET0" and "ENET1" portion of the card are disabled. These LEDs are lit in the following cases:

•When the enable/disable switch is in state disable (lit by hardware)

•After power-up, before the card is enabled

•When the ENET port on the card is disabled by software.
