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

The operating temperature inside the rack is always higher than the room temperature and is dependent
on the configuration of equipment in the rack. Check the TMRA for each piece of equipment before
installation.
CAUTION: To reduce the risk of damage to the equipment when installing third-party options:
• Do not permit optional equipment to impede airflow around the frame or to increase the internal
rack temperature beyond the maximum allowable limits.
• Do not exceed the manufacturer's TMRA.

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" 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", with an adjustability range of plus
½" to minus 1 ½". The rails will work in both a 1075 mm and a 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 pounds. Four of these frames together approach the 2,250 pound 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 inches.
1075 racks with side facing PDUs may interfere with the frame. Hewlett Packard Enterprise recommends
using 1200 mm racks.
