Power Requirements for Sourcefire Devices
3D8120/8130/8140 and 3D8250/8260/8270/8290
Appendix A
Separate circuits are required to create redundant power sources. Use an
uninterruptible or battery-backed power source to prevent power status issues or
power loss due to input line power glitches.
Supply sufficient power to each power supply to run the entire appliance. The
voltage and current ratings for each supply are listed on the label on the
appliance.
Use an external Surge Protection Device at the input of the network equipment
where the Sourcefire 3D System is to be installed.
Separate Circuit Installation
If separate circuits are used, each one must be rated the full rating of the
appliance. This configuration provides for circuit failure and power supply failure.
Example:
Each supply is attached to a different 220V circuit. Each circuit must be
capable of supplying 5A, as stated on the label.
Same Circuit Installation
If the same circuit is used to feed both supplies, then the power rating of one
supply applies to the whole box. This configuration only provides protection from
a power supply failure.
Example:
Both supplies are attached to the same 220V circuit. The maximum
draw from this circuit would be 5A, as stated on the label.
AC Voltage
The power supplies will work with these voltages: 100VAC to 240VAC nominal
(85VAC to 264VAC maximum). Use of voltages outside this range may cause
damage to the appliance.
AC Current
The labeled current rating for each supply is: 10A maximum over the full range,
per supply 5A maximum for 187VAC to 264VAC, per supply. Appropriate wire and
breakers must be used to reduce the potential for fire.
Frequency Range
The frequency range of the AC power supply is 47 Hz to 63 Hz. Frequencies
outside this range may cause the appliance to not operate or to operate
incorrectly.
Power Cords
The power connections on the power supplies are IEC C14 connectors and they
will accept IEC C13 connectors. A UL-recognized power cord must be used. The
minimum wire gauge is 16 AWG. The cords supplied with the appliances are 16
