1.6 Safety Instructions for Rack Mount Installations

• Rack Mount Brackets - Do not lift the NX-7500 series integrated services platform using the rack mount
brackets.
• Rack Mount Rails - Use only industry-standard mounting kits when installing the NX-7500 series integrated
services platform, as improper mounting may result in hardware failure and hazardous conditions. Motorola
recommends using the mounting rails included with the integrated services platform.
• Elevated Operating Ambient - If installing the NX-7500 series integrated services platform in a closed or
multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than the
room ambient. Consideration should be given to installing the appliance in an environment compatible with the
maximum ambient temperature (Tma) specified by the manufacturer.
• Reduced Air Flow - Installation of the NX-7500 series integrated services platform in a rack should be such that
the amount of air flow required for safe operation of the equipment is not compromised.
• Mechanical Loading - Mounting the NX-7500 series integrated services platform in a rack should be such that a
hazardous condition is not achieved due to uneven mechanical loading.
• Circuit Overloading - Consideration should be given when connecting the NX-7500 series integrated services
platform to the supply circuit so that protection is provided to the NX-7500 series integrated services platform
and supply wiring if any circuit overloads occur. Appropriate consideration of the equipment nameplate ratings
should be used when addressing this concern.
• Reliable Earthing - Reliable earthing of the rack mounted NX-7500 series integrated services platform 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).
1.7 NX-7500 Series Integrated Service Platform 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
