Figure 52: Removing a DC Power Supply
Figure 53: Disconnecting the DC Power Cables
Installing an MX5, MX10, MX40, and MX80 DC Power Supply
WARNING: Before performing DC power procedures, ensure that power is
removed from the DC circuit. To ensure that all power is off, locate the circuit
breaker on the panel board that services the DC circuit, switch the circuit
breaker to the off position, and tape the switch handle of the circuit breaker
in the off position.
To install a DC power supply (see Figure 54 on page 122):
1. Ensure that the voltage across the DC power source cable leads is 0 V and that there
is no chance that the cable leads might become active during installation.
2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
3. Switch the DC circuit breaker on the DC power supply faceplate to the off (O) position.
