NonStop NS1000 Planning Guide (H06.08+)

Rack offset is labeled on the rails in each side of the rack. These rails are measured vertically in
units called U, with one U measuring 1.75 inches (44 millimeters). The rack is 36U with 1U located
at the bottom and 36U at the top or 42U with 1U located at the bottom and 42U at the top. The
rack offset is the lowest number on the rack that the component occupies.
Blade Element Group-Module-Slot Numbering
• Group:
— In OSM Service Connection displays, 400 through 407 relates to blade complexes 0
through 7. Each blade complex includes a blade element and its associated processor.
Example: group 403 = blade complex 3
— In the OSM Low-Level Link, 400 relates to all blade complexes.
Example: group 400 = any blade complex
• Module:
— In OSM Service Connection displays, a module represents either the blade element or
the processor:
◦ In an Integrity NonStop NS1000 server, all blade elements are module 1.
Example: module 1 = any blade element
◦ 100-107 relates to processors 0-7
Example: module 102 = processor 2
— In the OSM Low-Level Link, 100 through 107 relates to processors 0 through 7.
Example: module 103 = processor 3
• Slot:
— In OSM Service Connection displays:
◦ 2 relates to the location of the ServerNet PCI adapter card in the PCI slots.
Only slot 2 is used.
◦ 3 through 4 relates to the location of the power supplies on the blade element.
Example: slot 3 = the power supply in slot 3
◦ 16 through 19 relates to the location of the fans on the blade element.
Example: slot 18 = the fan in slot 18
— In the OSM Low-Level Link, 1 relates to the location of the processor. Because each
blade element contains only one processor, it is always located in slot 1.
Example: slot 1 = any processor in any blade element.
• Port: X and Y relate to the two ServerNet fabric ports in slot 2.
Example: Port X = Right port connecting to the ServerNet X fabric when facing the blade
element from the rear.
These tables show the default numbering for the blade elements of an Integrity NonStop NS1000
system when blade elements are powered on and functioning:
