The flashing _Activity_ LED (middle one of the 3), with the Status LED On (Left one of 3, also green) should indicate that the unit is receiving network activity. If it is the _Status_ LED that is flashing, then the unit is either not configured, not able to reach the network, or running a self-test. In its ever-helpful way, the manual says that if the yellow Fault light is on, disconnect and reconnect the DC power to the unit. If the Fault LED again lights, "then replace the unit." :) -----Original Message----- From: chris [mailto:cb@mythtech.net] Sent: Friday, June 13, 2003 9:08 AM To: Classic Computer Subject: Re: JetDirect EX print server <snip> As soon as I connect the box to the network, it's activity light blinks for a few seconds, and then the Fault light comes on. If I also have the box connected to a printer, it dumps out a "Reboot" page to the printer, and gets stuck cycling like that (Goes to Ok, then fault, prints a page, repeat until I disconnect from the network). <snip>
