In order to provide power to equipment and experiments inside the MPLM during launch, the MPLM could be connected to the Shuttle's power supply by means of the [[Remotely Operated Electrical Umbilical]] (ROEU). The umbilical was mounted on the starboard side payload bay sidewall longeron, and was a folding arm umbilical that connected to the MPLM while it was in the payload bay. The arm was disconnected and retracted prior to the MPLM being removed for placement on the ISS and then reconnected once the MPLM was placed back inside the payload bay.
