Installation Overview
If a System Does Not Require EPO Capability
If a system does not require EPO capability, go to ServerNet Cabling on page 1-35.
System Organization
This subsection describes the organization, group numbering, and labeling in a
NonStop S-series system. For IOAM enclosure organization, see Group, Module, and
Slot Hierarchy for IOAM Enclosures on page 1-28.
A system consists of the hardware and the software that runs on it. To perform
hardware operations using the OSM or TSM package, you must be familiar with the
organization and naming conventions and know how to identify individual components
within the server.
OSM has a naming convention similar to, but more abbreviated than, the naming
convention for system resource locations in TSM. For example, TSM displays the
location of a fan CRU in this form:
FAN.GRP-1.MOD-1.SLOT-26
OSM displays the location of the same fan CRU in this form:
FAN (1.1.26)
Group, Module, and Slot Hierarchy for System Enclosures
Hardware in a server is organized according to a system, group, module, and slot
hierarchy, as follows:
A system enclosure can be serviced from two sides:
Term Definition
System A set of groups and external hardware components.
Group A set of components accessible to a pair of service processors (SPs) in a system
enclosure. In a NonStop S-series server, an enclosure contains one group.
Module A set of slots sharing a common hardware interconnect (such as a backplane).
Slot A labeled physical space in an enclosure in which a component can be installed.
Term Definition
Appearance
side
Contains fans, disk customer-replaceable units (CRUs), group ID switches,
and power monitor and control unit (PMCU) CRUs.
Service
side
Provides access to the PMF CRUs or IOMF CRUs as well as to the
ServerNet expansion boards (SEBs), modular SEBs (MSEBs), and ServerNet
adapters. Cables are also accessed from the service side.
