I received my base unit and an add-on hashing unit today.   I have both powered by a external server power supply.   The external unit was attached to the main unit.   The external unit's front LED started flashing right away, but no lights from the main unit's front LED.   I have an ethernet cable plugged into the base unit and it's lights were flashing, but nothing ever displayed on the HDMI display.   I let if it boot for several minutes and the main unit got warm - fan was working and I could see one RED and one green (flashing) LEDs on the main units hashboard.   This matched what LED's were lit on the add-on hashing unit.    I checked my router and saw no new DHCP devices getting an address.    The cable & switch port worked with a PC before moving the cable to the Apollo BTC.

Any thoughts?
