Rack and Offset Physical Location
Rack name and rack offset identify the physical location of components in an NS2100 system.
The rack name is located on an external label affixed to the rack, which includes the system
name plus a 2-digit rack number.
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 403 relates to blade complexes 0
through 4. 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 NS2100 system, all blade elements are module 1.
Example: module 1 = any blade element
–
100-103 relates to processors 0-3
Example: module 102 = processor 2
◦
In the OSM Low-Level Link, 100 through 103 relates to processors 0 through 3.
Example: module 103 = processor 3
•
Slot:
In OSM Service Connection displays:
◦
–
1 represents the ServerNet PCI adapter card.
The ServerNet PCI card is installed in the third PCI slot in the rx2800 i2.
–
3 and 4 represent the power supplies on the blade element.
OSM slot 3 represents power supply 1; OSM slot 4 represents power supply 2.
–
32 through 37 represent the fans on the blade element.
OSM slot 32 represents fan 1, OSM slot 33 represents fan 2, and so on.
◦
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 1.
These tables show the default numbering for the blade elements of an NS2100 system when
blade elements are powered on and functioning:
