NOTE:
For detailed specifications, see NSG 9000 data sheet.
Each module may be configured offline and when mounted into the slot, the system identifies
the inserted module. The modules are hot swappable and are mounted and plugged from the
rear side of the device.
For information on how to connect the ports, see
3.3 Connecting the QAM-RF Output Cables
on page 30.
1.6.3
Power Supply
The NSG 9000 device is furnished with two hot swappable redundant AC or DC power
supply units. Each power supply unit easily accommodates the power consumption of a fully
populated device. When both power supply units are plugged in and connected to the mains,
the power supply units operate in current sharing mode. For power consumption
specifications, see
1.3.3 Power Supply Specifications
on page 8.
The physical dimensions of the AC/DC power supply are: 40mmH x 90mmW x 440mmD.
Each power supply unit features two LEDs. The following table describes the LEDs:
For instructions to connect the AC power supply, see
3.7 Connecting Power
on page 31. For
overcurrent protection see
2.2.5.2 Overcurrent protection
on page 21.
The -48 VDC power supply unit is supplied with the required 3-pin male connector. See
Wiring the –48 VDC Power Supply
on page 36 for instructions to connect the power supply.
NOTE:
Consideration should be given to the connection of the equipment to the supply circuit and the
effect that overloading of circuits might have on overcurrent protection and supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing this concern.
