NonStop NS2400 Series Planning Guide

NonStop System With Data Center UPS, Both Power Rails
In this non-supported configuration, a NonStop system is installed in a Tier-I, Tier-II or Tier-III data
center. The data center tier classification is defined by the Uptime InstituteTM Tier Classifications
Define Site Infrastructure White Paper.
IMPORTANT: If this configuration is used, there is no guarantee that your data center will never
lose power.
Figure 60 shows an example of a non-supported configuration in a NonStop system with the left
and right PDUs connected to the data center UPS. In this configuration, OSM does not manage or
monitor the data center UPS.
