+24 VDC to the Active MAXNET Chassis backplane. 2.6. Voltage Monitor The MNAC and MNDC power supply module have test ports on the front panel. By connecting a DVM between the Pos (RED) and Neg (Black) port, the chassis backplane +24 VDC level can be monitored. MAXNET –... -
Page 9: Maintenance & Troubleshooting
Check the GREEN Power LED on each Power Supply module. If one is off or intermittent, then the chassis is not getting correct power. Refer to the MNAC/MNDC Not Powering Chassis troubleshooting section. If power availability is not an issue and other modules in the chassis are okay, the module itself is suspect. - Page 10 CHAPTER 3: MAINTENANCE & TROUBLESHOOTING This page left intentionally blank.

Grounding or Polarization: Precautions should be taken so that the grounding or polarization means of the device is not defeated. NOTE: When installing the MNAC or MNDC Power Supply, the GND bonding terminal #1 on the back of the MNAC or MNDC Power Supply shall be connected to the chassis ground lug. - Page 12 Power Supply Removal: Power (AC or DC) should be disconnected from the module before removing for replacement or service. This is accomplished by removing the AC IEC plug for the MNAC unit and wires from the terminal block of the MNDC unit.
