Chapter 4:
Power Connectivity Planning
This chapter is to be used in planning the power requirements and resources for the SG-
9100 system. Topics which are covered include:
AC Power Source Requirements
AC Cabling Requirements and Overcurrent Protection
Power Source Requirements
Installation of this equipment must comply with local and regional electrical regulations
governing the installation of information technology equipment by licensed electricians.
This equipment is designed to operate in installations covered by NFPA 70, 1999
Edition (National Electric Code) and NFPA-75, 1992 (code for Protection of Electronic
Computer/Data Processing Equipment).
WARNING
To reduce the risk of personal injury, fire, or damage to the
equipment, do not overload the AC supply branch circuit that
provides power to the rack. Consult the electrical authority
having jurisdiction over wiring and installation requirements of
your facility.
CAUTION
Protect the server from power fluctuations and temporary
interruptions with a regulating uninterruptible power supply.
This device protects the hardware from damage caused by
power surges and voltage spikes and keeps the system in
operation during a power failure.
When installing more than one Service Gateway, you may need to use additional power
distribution devices to safely provide power to all devices. Observe the following
guidelines:
Balance the power load between available AC supply branch circuits.
Do not allow the overall system AC current load to exceed 80% of the branch
circuit AC current rating.
Do not use common power outlet strips for this equipment.
Provide a separate electrical circuit for the Service Gateway.
