Power Requirements for Sourcefire Devices
3D7110/7120 and 3D7115/7125
Appendix A
3D7110/7120 and 3D7115/7125
This section describes the power requirements for the following Sourcefire
devices:
• 3D7110/7120 (GERY-1U-8-AC)
• 3D7115/7125 (GERY-1U-4C8S-AC)
These Sourcefire devices are suitable for installation by qualified personnel in
network telecommunication facilities and locations where the National Electric
Code applies. Note that this device is available only as an AC appliance.
Sourcefire recommends that you save the packing materials in case a return is
necessary.
For more information, see the following sections:
• See Installation on page 243 for circuit installation, voltage, current, and
frequency range, and power cord information.
• See Grounding/Earthing Requirements on page 244 for bonding locations,
recommended terminals, and ground wire requirements.
Installation
The Sourcefire 3D System must be installed in accordance with the requirements
of Article 250 of NFPA 70, National Electric Code (NEC) Handbook and local
electrical codes.
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.
