The following describes how to mount a PDU using two buttons only. If your PDU has circuit breakers implemented, read Circuit Breaker Orientation Limitation before mounting it.
To mount Zero U models using two buttons:
Turn to the rear of the PDU.
Locate two screw holes on the rear panel: one near the bottom and the other near the top (the side of cable gland).
Screw a button in the screw hole near the bottom. The recommended torque for the button is 1.96 N·m (20 kgf·cm).
Screw a button in the screw hole near the top. The recommended torque for the button is 1.96 N·m (20 kgf·cm).
Ensure that the two buttons can engage their mounting holes in the rack or cabinet simultaneously.
Press the PXE device forward, pushing the mounting buttons through the mounting holes, then letting the device drop slightly. This secures the PXE device in place and completes the installation.
