Power requirements

WARNING!
AC supply branch circuit that provides power to the rack. Consult the electrical authority having
jurisdiction over your facility wiring and installation procedures.
When planning for power distribution requirements for your rack configuration:
• The power load must be balanced between available AC supply branch circuits.
• The overall system AC current load must not exceed 80 percent of the branch circuit AC current
rating.
• If an uninterruptible power supply (UPS) is used, the load should not exceed 80 percent of the UPS
marked electrical current rating.
The installation of this equipment must be in accordance 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 the National Electric Code (ANSI/NFPA-70, 1993) and
the code for the Protection of Electronic Computer/Data Processing Equipment (NFPA-75, 1992).
WARNING!
region. Use of a non-HP approved power cord may result in: 1) not meeting individual country specific safety
requirements; 2) insufficient conductor ampacity that could result in overheating with potential personal
injury and/or property damage; and 3) fracturing resulting in the internal contacts being exposed, which
potentially could subject the user to a shock hazard. HP disclaims all liability in the event a non-HP approved
power cord is used.
For electrical power ratings on options, see the product rating label or user documentation supplied with
that option.

Grounding requirements

For proper operation and safety, all powered rack-mountable components are required to be properly
grounded in accordance with (NFPA-70, 1993), Article 250. All power distribution devices, branch
wiring, and receptacles must be listed as grounding-type devices.
When using power strips for electrical distribution, ensure that ground integrity is maintained for each
connection made. Plug each component into a reliably grounded outlet.
WARNING!
grounding feature. This equipment is designed to be connected to a grounded (earthed) power outlet that
is easily accessible and located as close as possible to the equipment. The grounding plug is an
important safety feature.
