How to Remove the Removable Media
Assembly (RMA)
Caution -
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.
