Grounding Requirements; Supported Racks And Rack Options; Rack-Free Environment Requirements - HPE Synergy 12000 Frame Setup And Installation Manual

Grounding requirements

This equipment must be grounded properly for proper operation and safety. In the United States, you must install the
equipment in accordance with NFPA 70, 1999 Edition (National Electric Code), Article 250, as well as any local and
regional building codes.
In Canada, you must install the equipment in accordance with Canadian Standards Association, CSA C22.1, Canadian
Electrical Code.
In all other countries, you must install the equipment in accordance with any regional or national electrical wiring codes,
such as the International Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore, you must be sure
that all power distribution devices used in the installation, such as branch wiring and receptacles, are listed or certified
grounding-type devices.
Because of the high ground-leakage currents associated with this equipment, Hewlett Packard Enterprise recommends
the use of a PDU that is either permanently wired to the building's branch circuit or includes a nondetachable cord that is
wired to an industrial-style plug. NEMA locking-style plugs or those complying with IEC 60309 are considered suitable for
this purpose. Using common power outlet strips to supply power to this equipment is not recommended.

Supported racks and rack options

The frame and support rails are engineered for mounting into a 19 in (48.26 cm) wide front panel, 4-post cabinets, and
racks that have been designed according to the EIA-310-D standard.
Hewlett Packard Enterprise rails are not compatible with tapped holes. There are two types of supported rail sets for the
frame:
• A set for square-hole front and rear mounting flanges
• A set for round-hole flanges
The rails are compatible with a nominal rack-mounting depth of 29 1/8 in (73.98 cm), with an adjustability range of plus
½ in (1.27 cm) to minus 1 ½ in (3.81 cm). The rails will work in both a 42.32 in (1075 mm) and a 47.24 in (1200 mm)
deep rack.
A 42U/47U rack supports up to four frames.
While the square-hole rail set is the standard option, either rail set supports a fully loaded frame weighing 550 lb (249.48
kg). Four of these frames together approach the 2,250 lb (1247.38 kg) internal IT equipment limit of both the HPE 42U x
600 mm x 1075 mm and the 42U 600 mm x 1200 mm 11000G2 Series QS racks.
NOTE: The HPE Synergy 12000 Frame is deeper than the c7000 enclosure by approximately 3.5 in (8.89 cm). 42.32 in
(1075 mm) racks with side-facing PDUs might interfere with the frame. Hewlett Packard Enterprise recommends using
47.24 in (1200 mm) racks.
Cables, PDUs, and other cable management hardware could increase the weight sufficiently to require the use of the HPE
42U x 600 mm x 1200 mm Intelligent Series QS rack, which supports 2,750 lb (1247.38 kg) internal IT equipment.

Rack-free environment requirements

The HPE Synergy 12000 Frame (referred to as the frame) can be used in a rack-free environment. The following
conditions must be met when performing a rack-free installation:
• A fully-populated frame can weigh up to 249.50 kg ( 550.00 lb). The object supporting the frame must be able to
withstand this weight.
• Always place the frame on a sturdy, flat surface.
