   | combination of the following: Card is not attached to an   |
   | active network, the card is not selected in the control    |
   | panel, AppleTalk is not enabled in the Chooser, the hybrid |
   | transceiver on the card is defective, there are no active  |
   | stations on the network, the Mac's -12VDC power supply is  |
   | malfunctioning, the hub is defective, or there is a break  |
