We have the Cisco 3550 switch and it looks like the unit is not able to negotiate the power with the switch. It keeps cycling over and over.

This happens because with default settings, the switch port is resetting power too quickly. Therefore, on the 3550 switch, on the switch port that the unit is attached to, please try adding the following CLI command:

  • power inline delay shutdown 20 initial 300

That should keep power supplied until the unit can boot up all the way.

I see in the electrical connection diagram in the user’s guide that there is a High PIV Ultra Fast switching diode. Do I need it and if so do you have a source?
The Guardian device connected to a Dell Powerconnect 3524P or 3548P port did not stay linked up. The device comes up, and then it goes down, and then it comes up cycling.
