Figure 4-6 Distribution Of Input Power For Each Bulk Power Supply - HP Integrity rx8620 User's & Service Manual

For information on how input power cords supply power to each BPS, see Figure 4-6.

WARNING
connected. This voltage is present even when the main power switch is in the off
position. To completely remove power, all power cords must be removed from the
server. Failure to comply could result in personal injury or damage to equipment.
Do not route data and power cables together in the same cable management arm.
CAUTION
Do not route data and power cables in parallel paths in close proximity to each other. The
suggested minimum distance that the data and power cables should be apart is 3 inches
(7.62 cm).
The power cord has current flowing through it, which creates a magnetic field. The potential to
induce electromagnetic interference in the data cables exist, thereby causing data corruption.
The server can accomodate a total of six BPSs. N+1 BPS capability describes the server having adequate
BPSs plus one additional module installed. If one BPS fails, adequate power will still be supplied to the cell
board(s) to keep the server partition(s) operational. Replace the failed BPS promptly to restore N+1
functionality.
A minimum of two BPS are required to bring up a single cell board installed in the server. This minimum
configuration is not N+1 capable. See Table 4-2 for BPS to cell board N+1 configurations.
