How to Remove the Removable Media Assembly (RMA)

Removing the removable media assembly activates the system power interlock switches. This safety mechanism prevents all DC voltages (except 5V standby power) from reaching any internal component when the removable media assembly is removed and the front panel keyswitch is left on. Do not remove the removable media assembly while the system is operating or the system will power off abruptly.
