Hello Damian,
One thing I do notice is that your boot code has not been updated to match your firmware. The firmware itself is also one version behind, so I would upgrade that as well.
1.3.7.18 firmware and bootcode is available here: SG200-50P Downloads
In order to upgrade the firmware you will need some sort of TFTP software.
Hope that helps,
