CHAPTER 1: PRODUCT DESCRIPTION
PRODUCT DESCRIPTION

Product Description
The MNAC and MNDC are modular power supplies that supply the required +24 VDC to the MAXNET Active Chassis
backplane. This allows any MAXNET active module (AMP’s, RF Switch) to be installed in any remaining active chassis slot
to receive power. Both MNAC and MNDC have 24 VDC redundant powering capabilities, although only the MNDC provides
true load sharing. Installing two power supply modules into the chassis will maintain power to the backplane in the event that
one of them fails. Both the MNAC and the MNDC include a 24 VDC rear terminal block connection for the remote chassis
powering options. They are connected to the Active MAXNET Chassis through a hot-swapping backplane. The MNAC and
MNDC modules feature front panel LED power indication and +24 VDC backplane voltage monitor connections.
In addition to the standard powering modules, an optional current monitoring function is available in both the MNAC and
MNDC to provide remote indication (via the rear terminal block) of current fluctuations caused by an active module failure.
The MNRPS is a module that supplies power to an Active MAXNET Chassis backplane from a remote 24 VDC source. It
features front panel LED power indication and +24 VDC backplane voltage monitor connections.

CHAPTER 2: INSTALLATION
INSTALLATION
2.Installation
2.1.
Product Inspection
Carefully unpack the power supply module from the shipping box. If the box or power supply module is damaged, please
notify the freight company to make a damage claim. If you suspect that there is a problem with the power supply module that
may affect it’s safe operation, do not install such a suspect Power Supply into the Active MAXNET Chassis.
NOTE: This equipment is intended for installation in a RESTRICTED ACCESS LOCATION only.
NOTE: Not for use in a computer room as defined in the Standard for Protection of Electronic Computer/Data Processing
Equipment, ANSI/NFPA 75.
Rack Mounting Precautions
a) Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature
of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing
the equipment in an environment compatible with the maximum ambient temperature (35ºC) specified by the
manufacturer.
b) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of airflow required for
safe operation of the equipment is not compromised.
c) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not
achieved due to uneven mechanical loading.
d) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit
and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing this concern.
e) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should
be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).
2.2.
Module Installation into the Active MAXNET® Chassis
Slide the MNAC or MNDC or MNRPS power supply module into an open slot in the Active MAXNET Chassis, until the module
seats into the chassis. Finger tighten the upper and lower knurled screws to lock the module into the chassis. If the power
supply is an MNAC module, connect an appropriate power cord (depending on the voltage rating used and the plug type
required at the installation site) to the MNAC’s IEC power inlet.
If the power supply is an MNDC module, use bus wire to connect the -48 VDC to the terminal block on the back of module
following the terminal block labeling (see Table 3 below). A disconnect device is required between the -48 VDC supply and
the MNDC power supply.
If the power supply is an MNRPS module, use bus wire to connect the +24 VDC to the terminal block on the back of module
following the terminal block labeling (see Table 3 below).

DC Redundant Powering of Active MAXNET® Chassis
If more than one power supply is connected to the chassis, the extra power supply acts as a redundant source of power.
Using internal logic within the module (MNAC uses diode steering, MNDC uses load sharing logic) if the dominant power
supply in the chassis fails, the other power supply becomes the active supplier to the +24 VDC chassis backplane ensuring
that power is maintained to all active modules in the chassis.

CHAPTER 3: MAINTENANCE & TROUBLESHOOTING
MAINTENANCE & TROUBLESHOOTING
3.
Maintenance & Troubleshooting
3.1.Maintenance
Daily, ensure that the Power LED’s are on for all of the power and active modules.
3.2.Troubleshooting
The following guide will help the operator to diagnose problems in active modules or chassis’. If none of the items in this
section are of help, please contact ATX for Technical Support.
3.2.1. Module Will Not Fully Insert into Chassis
a) Remove the module and inspect it for damage or bent guide rails.
b) Inspect the chassis for bent metal or obstructions.
c) Be sure that the active module is inserted such that the left side is above an odd numbered slot and the right side is
above an even number slot.
d) Try the module in a different slot. Due to machinery tolerances, some modules may be more snug in some slot than
others. If the tolerances are unacceptable, contact ATX.
3.2.2. Module Power LED Off or Intermittent
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. Continue.
Remove the suspect module and trade slot positions with another functioning module.
a) If the suspect module is okay and the previously good module fails, contact ATX and report a defective chassis.
b) If the suspect module fails and the previously good module is okay, contact ATX and report that the suspect module
is defective.
3.2.3. MNAC/MNDC Not Powering Chassis
NOTE: 220 VAC applied to an MNAC 110 will damage the module, but 110 VAC applied at an MNAC-220 will simply not turn
it ON.
a) Check the fuse continuity on the MNAC or MNDC module
b) Verify that the 110 VAC/220 VAC electrical outlet is active using a voltmeter and checking the circuit breaker (in the
case of the MNDC, insure that there is -48 VDC on the rear terminal block).
c) Verify that the IEC power cord is properly inserted into the receptacle on the rear of the module and properly
connected to a 110 VAC/220 VAC electrical outlet.
