UPS and ERM (Optional)
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 to each of the two ServerNet switch boards in the IOAM enclosure
•
At least two connections to the G4SAs installed in the IOAM 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) on page 2-3.
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 high 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 up 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 will 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.
