Power Connections
To make the power connections for the MX3 chassis, perform the following steps:
1. Connect the frame ground from the frame ground lug on the rear panel of the MX3 chassis
to the equipment rack grounding screw using appropriately sized wire that is at least the
same gauge as the power wiring.
2. Test the frame ground connection to ensure proper ground. Using a multimeter set to its
lowest resistance range, place one lead on the ground strap of the rack and the other on
the chassis frame ground terminal. The reading should be less than 0.1 ohm. Readings
greater than 0.1 ohm should be further investigated.
3. Make power connections to the MX3 chassis.
