Correct - this is just an LED using the 5v DC from the MXP to know it is connected. The resistor R1 is just a current limiting resistor for the LED. Value should be around 150R for an average 2v @ 20mA LED.

We changed from surface mount to through hole at the last minute for this set of boards (since there was only 1 SMT part left..), and didn't notice we had missed the value on the schematic.
