Overview 8
HP R18000DF
When the power unit is fully seated within the rack, Discovery Services connectors meet with a rack-mounted
EEPROM strip. Discovery Services reports the specific location of the power unit and a calculated location of
any battery packs. The battery packs must be installed directly beneath the power unit in the rack, without a
U gap, for Discovery Services to locate them. Racks without pre-installed EEPROM strips may be upgraded
by ordering and installing the strips, available on the HP website
(
http://www.hp.com/products/rackoptions ).
REPO port
The power unit includes an isolated REPO port. When properly wired, the REPO feature enables the power
at the UPS output receptacles to be switched off from a remote location. To use this feature, the REPO port
must be connected to a remote, normally open switch (not supplied). The REPO switch is used in conjunction
with a main disconnect device that removes the AC source from the input of the power unit.
When the switch is closed:
•
The REPO feature immediately powers down protected devices and does not utilize an orderly
shutdown procedure.
•
The REPO feature shuts down power units operating under utility, generator, or battery power.
To connect a REPO port, see either "Connecting the R12000DF REPO port (on page 49 )" or "Connecting the
R18000DF REPO port (on page 54 )." To restore power to the load devices after the REPO feature has been
activated, see "Restoring power after a REPO activation (on page 79 )."
