NonStop NS1000 Planning Guide (H06.08+)

Each PDU is wired to distribute the load segments to its receptacles.
CAUTION: If you are installing Integrity NonStop NS1000 system enclosures in a rack, balance
the current load among the available load segments. Using only one of the available load segments,
especially for larger systems, can cause unbalanced loading and might violate applicable electrical
codes. Connecting the two power plugs from an enclosure to the same load segment causes
failure of the hardware if that load segment fails.
Blade Element
The blade element for the Integrity NonStop NS1000 server is an “HP Integrity rx2620 Server
Description” (page 57). An Integrity NonStop NS1000 system supports up to eight blade elements
configured in pairs. Because modular hardware provides flexibility in how hardware is distributed
in a rack and without the optional rackmounted HP R5500 XR UPS, up to eight blade elements
can be installed in a single footprint. When the system includes the optional rackmounted HP
R5500 XR UPS, up to four blade elements can be installed in a single footprint.
To reduce ambiguity in identifying proper cable connections to the blade element, an identification
convention uses numbers to refer to each connection. A number such as 1, 2, 3, and 4 identifies
each blade element. These IDs reference the appropriate blade element for proper connection of
the fiber-optic cables. For more information, see “ServerNet Fabric I/O” (page 40).
This simplified example shows connections from two blade elements to the ServerNet-to-processor
ports in the VIO enclosures:
