NonStop NS1000 Planning Guide (H06.08+)

HP NonStop Open System Management (OSM). For a general description of the maintenance
switch, refer to the NonStop NS14000 Planning Guide. Details about the use or implementation of
the maintenance switch that are specific to an Integrity NonStop NS1000 server are presented
here.
The Integrity NonStop NS1000 system requires multiple connections to the maintenance switch:
• One connection from the ME ENET port on each of the two VIO enclosures
• One connection from slot 6B, port A on each of the two VIO enclosure for the OSM Service
Connection and OSM Notification Director:
• One connection to the optional UPS module
• One connection for the system console running OSM
UPS and ERM (Optional)
An uninterruptible power supply (UPS) is optional but recommended where a site UPS is not
available. You can use any UPS that meets the modular cabinet power requirements for all
enclosures being powered by the UPS. One UPS option is the HP R5500 XR UPS. For information
about the requirements for installing a UPS other than the HP R5500 XR UPS in an Integrity
NonStop NS1000 system, see “Uninterruptible Power Supply (UPS)” (page 20).
Cabinet configurations that include an R5500 XR UPS also have one extended runtime module
(ERM). An ERM is a battery module that extends the overall battery-supported system run time.
A second ERM can be added for even longer battery-supported system run time.
Adding an R5500 XR UPS to a modular cabinet in the field requires removing the PDU on the
right side of the modular cabinet and installing HP extension bars that are compatible with the
UPS. A factory-installed UPS ships with the HP extension bars already installed on the right side
of the modular cabinet. The PDU and extension bars are oriented inward, facing the components
within the rack. Both the UPS and the ERM are 3U and must reside in the bottom of the cabinet.
NOTE: Retrofitting a system in the field with a UPS and ERMs will likely require moving all
installed enclosures in the rack to provide space for the new hardware. One or more of the
enclosures that formerly resided in the rack might be displaced and therefore have to be installed
in another rack that would also need a UPS and ERMs installed. Additionally, lifting equipment
might be required to lift heavy enclosures to their new location.
