2 General Site Preparation Guidelines The following information provides general principles and practices to consider before the installation or operation of the system. Chapter 2 11 - HP Server rp7420 | Site Preparation Guide, Third Edition - HP 9000 rp7420 Server - Page 20
room safety • Power consumption • Electrical load requirements (circuit breaker sizing) • Power quality • Distribution hardware • System installation guidelines Computer Room Safety Inside the computer room, fire protection and adequate lighting (for equipment servicing) are important safety - HP Server rp7420 | Site Preparation Guide, Third Edition - HP 9000 rp7420 Server - Page 21
of the server. Power Consumption When determining power requirements, you must consider any peripheral equipment that will be installed during initial installation or as a later update. Refer to the applicable documentation for such devices to determine the power required to support these devices - HP Server rp7420 | Site Preparation Guide, Third Edition - HP 9000 rp7420 Server - Page 22
from that of other metals used in power hardware. Because of this difference, aluminum conductors can cause connector hardware to loosen, overheat, and fail. Raceway Systems (Electrical Conduits) Raceways (electrical conduits) form part of the protective ground path for personnel and equipment - HP Server rp7420 | Site Preparation Guide, Third Edition - HP 9000 rp7420 Server - Page 23
Panel Ground Each power panel should be grounded to the electrical service entrance with green (green/yellow) wire ground conductors. The green (green/yellow) wire ground conductors should be sized per applicable codes (based on circuit over current device ratings). NOTE The green wire ground - HP Server rp7420 | Site Preparation Guide, Third Edition - HP 9000 rp7420 Server - Page 24
, install a complete signal reference grid for maintaining equal potential over a broad band of frequencies. The grid should be connected to the equipment cabinet and electrical service entrance ground at multiple connection points using a minimum #6 AWG (16 mm) wire ground conductor. The following - HP Server rp7420 | Site Preparation Guide, Third Edition - HP 9000 rp7420 Server - Page 25
for connection to service entrance ground and server equipment). The use of conductive floor end to the nearest pedestal base (raised floor) or cable trough ground point (nonraised floor). 3. Check that the braid contact on each end of the ground straps consists of a terminal and connection hardware - HP Server rp7420 | Site Preparation Guide, Third Edition - HP 9000 rp7420 Server - Page 26
. Some common problems are highlighted. Both power cable and data communications cable installations are discussed. NOTE In domestic installations, the proper receptacles should be installed before the arrival of HP equipment. Refer to the appropriate installation guide for installation procedures - HP Server rp7420 | Site Preparation Guide, Third Edition - HP 9000 rp7420 Server - Page 27
at a positive pressure relative to surrounding spaces. • Use a vapor barrier installed around the entire computer room envelope to restrain moisture (or local code minimum clearance) from the top of the server cabinet to the fire sprinkler heads.
