Power Supplies
NX-7510 and NX-7530 integrated services platforms are initially configured with a single AC power
supply. An NX-7520 integrated services platform is initially configured with two DC power supplies.
Installation of an Uninterruptible Power Supply (UPS) is recommended if a second power supply is
installed in an NX-7510 or NX-7530. To replace a failed power supply or install a new power supply, see

Power Protection
•
If possible, use a circuit dedicated to data processing equipment. Commercial electrical contractors
are familiar with wiring for data processing equipment and can help with the load balancing of these
circuits.
•
Install surge protection. Be sure to use a surge protection device between the electricity source and
the NX-7500 series integrated services platform.
•
Install an Uninterruptible Power Supply (UPS). A UPS provides continuous power during a power
outage. Some UPS devices have integral surge protection. UPS equipment requires periodic
maintenance to ensure reliability. A UPS of the proper capacity for the data processing equipment
must be purchased.
