4 Neoview Platform Installation Site Guidelines
Neoview Platform Power and I/O Cable Entry
You can order the segment and combination cabinets with the PDU junction boxes installed:
• Top rear: Power cables are routed from above the cabinet.
• Bottom rear: Power cables are routed from below the cabinet (HP recommended).
I/O cables can enter the Neoview platform segment and combination cabinets from the bottom
rear, top rear, or rear sides of the cabinet. HP recommends installing the cabinet on a raised floor
and routing I/O cables through the top rear or bottom rear of a cabinet.
Emergency Power-Off Switches
NOTE: A system-wide uninterruptible power supply (UPS) is required for the Neoview platform.
For information about powering off the Neoview platform, see “Emergency Power-Off Procedure”
(page 13).
Emergency Power-Off (EPO) switches are required by local codes or other applicable regulations
when computer equipment contains batteries capable of supplying more than 750 volt-amperes
(VA) for more than five minutes. Systems that have these batteries also have internal EPO
hardware for connection to a site EPO switch or relay. In an emergency, activating the EPO
switch or relay removes power from all electrical equipment in the computer room (except that
used for lighting and fire-related sensors and alarms).
Electrical Power and Grounding Quality
Proper design and installation of a power distribution system for the Neoview hardware requires
specialized skills, knowledge, and understanding of appropriate electrical codes and the limitations
of the power systems for computer and data processing equipment.
Power Quality
The Neoview platform is designed to operate reliably over a wide range of voltages and
frequencies described in “Enclosure AC Input” (page 30). However, damage can occur if these
ranges are exceeded. Severe electrical disturbances can exceed the design specifications of the
equipment. Common sources of such disturbances are:
• Fluctuations within the facility’s distribution system
• Utility service low-voltage conditions (such as sags or brownouts)
• Wide and rapid variations in input voltage levels
• Wide and rapid variations in input power frequency
• Electrical storms
• Large inductive sources (such as motors and welders)
• Faults in the distribution system wiring (such as loose connections)
You can protect the Neoview platform from the sources of many of these electrical disturbances
by using:
• A dedicated power distribution system
• Power-conditioning equipment
• Lightning arresters on power cables to protect equipment against electrical storms
To ensure proper power for the Neoview platform, consult your HP site preparation specialist
or power engineer.
