For other UPSs, see the documentation shipped with the UPS.
ERM (Optional with UPS)
Cabinet configurations that include the HPE UPS can also include extended runtime modules
(ERMs). An ERM is a battery module that extends the overall battery-supported system run time.
Up to two ERMs can be used for even longer battery-supported system run time.
Enterprise Storage System — ESS (Optional)
An Enterprise Storage System (ESS) is a collection of magnetic disks, their controllers, and a
disk cache in one or more standalone cabinets. ESS connects to the Integrity NonStop NS-series
systems either directly via Fibre Channel ports on the Storage CLIM (direct connect) or through
a separate storage area network (SAN) using a Fibre Channel SAN switch (switched connect).
For more information about these connection types, see your Hewlett Packard Enterprise service
provider.
NOTE:
The Fibre Channel SAN switch power cords might not be compatible with the modular
cabinet PDU. Contact your Hewlett Packard Enterprise service provider to order replacement
power cords for the SAN switch that are compatible with the modular cabinet PDU.
Cables and switches vary, depending on whether the connection is direct, switched, or a
combination:
