PROBLEM TO BE SOLVED: To eliminate electrification and short-circuiting without using a tool for opening and closing a safety cover when a redundant power supply unit is mounted. SOLUTION: A frame-like safety cover 10 is fixed to a power supply slot rotatively by a screw 14 using an upper side as a supporting point. When a power supply unit is inserted to a power supply slot, a safety cover lock rod 15 unlocks the safety cover 10 to rotate. When a power supply unit is pulled out, it is pressed by the dead weight and rotates, and locks the safety cover 10 which closes an inlet of a power supply slot. |
