I recently purchased a used BLUESOUND Vault V500

I purchased the BLUESOUND VAULT V500 (used but in the box) and followed the setup instructions to a tee with a Ethernet Cat5 cable to my router port and plugged in the power supply with high hopes but no LED lit up on the top of the unit and also I can not add the vault to my BluOS Control on either my IPhone or IPad! I tried calling BLUESOUND support and left messages and emailed them three times with one useless reply telling me there is no WiFi card in the Vault ( I knew that which is why I connected via Ethernet). I would appreciate any help for someone who struggled with the Vault500. Thank you so much!
