— R12000DF—1U
— R18000DF—2U
o Optional 3U lead acid or 1U lithium-ion battery packs
o A minimum of 60 seconds of backup power with one battery pack and 5 minutes of backup power
with two battery packs provided for the maximum load
• Advanced battery management to increase battery service life and optimize recharge time
o Warning before the end of the useful battery life
o Easily replaceable battery modules that simplify maintenance
• Configurable utility and generator battery charge power level switching
• Optional HP DirectFlow UPS Management Module network connectivity with advanced remote
monitoring, control, and management features
• Built-in location awareness of components
• Emergency shutdown control through a REPO port
• Firmware that is service upgradeable through a standard DB-9 serial communication port
• Backed by worldwide agency approvals
To benefit from product enhancements, update to the latest versions of UPS firmware and software. To
download the UPS firmware and software, see the HP website (http://www.hp.com/go/rackandpower).
Power management options
The DirectFlow UPS is comprised of an HP DirectFlow Power Unit configured with either HP DirectFlow VRLA
Battery Packs (3U) or an R12000DF (1U) or R18000DF (3U) HP DirectFlow Lithium-ion Battery Pack.
The DirectFlow UPS works within an overall power management plan that can include utility, generator, and
battery power.
The power unit includes front panel controls and an LCD screen for navigating UPS menu options (on page
73) to access system values. Certain values can be configured to accommodate your power management
plan.
Each battery pack provides a minimum of 60 seconds of backup power as a stopgap for a power supply lag
or outage. Depending upon configuration, including the number of battery packs and load requirements, the
Overview 6
UPS can extend backup power for an increased amount of time. Distribute the load as evenly as possible
across the UPS configuration to most efficiently use the powerful three-phase UPS design.
The UPS modes of operation allow the UPS to transfer seamlessly between AC, Battery, and Bypass modes
to supply power to connected devices without interruption. For more information, see "Working with UPS
modes of operation (on page 76)." The power unit can use a built-in, time-based algorithm to switch between
utility and generator battery charging power levels when transferring operating modes. Using a lower
charge level while the UPS runs on generator power maximizes the output available to connected devices.
The Management Module provides additional features to receive generator commands. To set UPS battery
charge power levels, see "Configuring the battery charge power levels (on page 75)."
Advanced monitoring and management features
The Management Module card reports detailed information to the Management Module web interface
where the information is graphically displayed. Many commands and functions can be customized from the
interface. Customizable setup options in the UPS Service Menu can also be accessed using the Management
Module card. The Management Module is designed specifically for the DirectFlow UPS. It is not intended for
installation in other UPS devices.
To install and initially configure the Management Module in the DirectFlow UPS, see "Installing the
Management Module card (on page 57)" and "Accessing the Management Module (on page 63)." For
details about using the Management Module card and web interface, see the HP DirectFlow UPS
Management Module User Guide on the HP website (http://www.hp.com/support/DFUPS_MM_UG_en).
Location Discovery Services for the UPS configuration
HP provides built-in location awareness of rack components, a capability that works hand-in-hand with
technology in the new HP Intelligent Series racks. Together, the technologies provide the rack identification
number and precise U location of the components. This information is communicated through power
management software.
HP R12000DF
Overview 7
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)."

Configuring the battery charge power levels
Different battery charge power levels can be set in the power unit for utility and generator input sources. A
higher charge power level like 1100 W or 550 W can be set for utility input, and a lower charge level, 190
W or 0 W, can be set for generator input to reserve AC power for loads while running on generator input.
By default, the power unit uses a built-in algorithm to determine when to switch battery charge power levels.
For instance, when there is a power outage the UPS transfers from AC mode to Battery mode. If the input AC
becomes available before 10 seconds or after 60 seconds, the power unit automatically remains at the
charge power level defined for utility input. However, if the input AC becomes available again between 10
and 60 seconds, the power unit switches to the battery charge power level defined for generator input. The
power unit remains at the generator charge power level until the defined on-generator time period expires,
and then the power unit switches back to the charge power level defined for utility input.
To set the power unit battery charge power levels from the Settings menu:
1. Select Input source, scroll to Utility & Gen, and then press Enter.
Utility & Gen is the default setting. To disable the built-in algorithm, select Utility Only.
UPS operations 75
2. Select Charger Limit-Gen, scroll to the wattage, and then press Enter.
The default charger limit wattage setting is 0 W.
3. Select Charger Limit-Uti, scroll to the wattage, and then press Enter.
The default charger limit wattage setting is 555 W.
4. Select On-Gen Duration, scroll to the time period, and then press Enter.
The default on-generator duration is 30 minutes.
The Management Module can override the default settings for charge power level switching by initiating an
immediate switch to the generator charge power level if the Management Module receives a SNMP request
with an on-generator command from a generator system. The on-generator command must be received
within 15 minutes of the AC input power becomes available again or the power unit will use the default time
periods. The power unit will switch back to the utility charge power level either after an off-generator
command is received or after the defined on-generator period of time expires. To set up the Management
Module to receive generator commands, see the HP DirectFlow UPS Management Module User Guide.
Changing the language
To change the display language on the power unit:
1. Scroll through the main menu and select Settings.
2. Select Language.
3. Press the Up or Down arrow to scroll to the language.
4. Press the Enter button to save the change.
Working with UPS modes of operation
The UPS modes of operation result from current operating conditions and the parameters that provide power
protection to connected load devices. Some mode options can be set or adjusted using the UPS menu options
(on page 73).
The UPS has the following modes of operation:
• AC mode (on page 76)
• Battery mode (on page 77)
AC mode
• Bypass mode (on page 77)
When the UPS operates in AC mode:
• Power is available at the UPS receptacles.
• The power unit actively filters and mitigates harmonics and power factor.
• The power unit charges the batteries as necessary.
• The UPS transfers to Battery mode (on page 77) or Bypass mode (on page 77) as necessary.
An audible buzzer sounds briefly to indicate the UPS is powering up when the power unit is connected to
utility power. If no utility power is available, the UPS might enter Battery mode.
UPS operations 76
Battery mode
When another power source is unavailable, the UPS automatically operates on battery power in Battery
mode:
• Power is available at the UPS receptacles for a minimum of 60 seconds per battery pack.
• The UPS automatically transfers back to AC mode (on page 76) when that input is available again.
To turn the UPS completely off from Battery mode, press the Off button for 3 seconds.
Bypass mode
The UPS automatically enters Bypass mode when one of the following conditions occurs:
• Extended overload
• Over temperature
• Output short
• Hardware failure
In Bypass mode, utility power continues to be passively filtered by the UPS. To troubleshoot operating
problems or conditions that might transfer the UPS into Bypass mode, see "Troubleshooting (on page 89)."
To transfer from Bypass mode to AC mode (on page 76) after any operating problems are resolved, press the
On button for 3 seconds.

By default, all UPS components except the Management Module card are flashed during the upgrade. For
more information about using a utility to update or configure the Management Module card, see the HP
DirectFlow UPS Management Module User Guide.
Restoring power after a REPO activation
IMPORTANT: If the UPS was operating on battery power when the remote switch was closed, no
power is available to the load devices until utility power is restored and the UPS has been
manually powered up.
To restore power to the load devices after the REPO feature is activated:
1. Connect the REPO port. To connect a REPO port for an R12000DF power unit, see "Connecting the
R12000DF REPO port (on page 49)." To connect a REPO port for an R18000DF power unit, see
"Connecting the R18000DF REPO port (on page 54)."
2. Press the On button after the AC source is reconnected to the UPS.
IMPORTANT: Pressing and holding the On button without utility present normally initiates a
battery start and the UPS assumes the load. If the On button is pressed and a REPO is detected,
the battery start is inhibited and the UPS is not able to assume the load. The electronics module fan
spins and the UPS fault LED and an audible alarm is active as long as the On button is held.
To power down the entire network in the event of an emergency, the REPO ports of multiple power units can
be connected to a single switch.
Verifying the REPO port connection
IMPORTANT:
Verify the connection after connecting the REPO port:

General alarm condition
Action:
1. If using the HP DirectFlow UPS Management Module web interface, check the log files to obtain specific
error information to help identify the problem.
For more information about the causes of a general alarm condition, see "LED and audible alarm
troubleshooting (on page 89)."
2. Check the batteries:
a. Allow the UPS batteries to charge for 48 hours.
b. If a battery fault occurs, replace the batteries.
3. Reduce the load:
a. Power down the UPS. For more information, see "Powering down the UPS and battery packs (on
page 80)."
b. Remove one or more load devices to reduce the power requirements.
Troubleshooting 92
c. Wait at least 5 seconds and restart the UPS.
d. If the condition persists, verify that the load devices are not defective.
4. Allow the UPS to cool:
a. Power down the UPS. For more information, see "Powering down the UPS and battery packs (on
page 80)."
b. Clear vents and remove any heat sources.
c. Verify that the airflow around the UPS is not restricted.
5. Wait at least 5 minutes and restart the UPS.
6. If the condition persists, contact an HP authorized service representative.
7. If a battery fault occurs, replace the batteries.
UPS does not start
Action:
Verify the following:
1. The power cord is connected to a utility power receptacle.
2. The power module is attached to the power unit and the manual bypass switch is in the normal position.
3. The input voltage is within normal voltage range.
Wiring condition
Action: Contact a qualified electrician to verify the following:
• The line wires are not reversed in the wall outlet.
• A neutral wire connection exists.
Utility power condition
Possible cause:
The input voltage is not within +10 or -15 percent of nominal voltage.
The UPS is receiving utility power that might be unstable or in brownout conditions. The UPS continues to
supply power to the connected equipment. If conditions worsen, the UPS might switch to battery power.
Action:
1. Check the input voltage and reconfigure the UPS using the UPS menu options (on page 73).
2. Contact a qualified electrician to verify that the utility power is suitable for the UPS.
Battery connection condition
Possible cause:
• The power cable or signal cable is not connected.
• The battery circuit breaker is not switched on.
Troubleshooting 93
• One or more battery strings are disconnected.
Action:
1. Be sure that all the battery modules are fully seated and locked in place.
2. If the condition persists, contact an HP authorized service representative.
REPO condition
Action:
• If the remote switch is closed, then open the switch to enable power to the output receptacles.
• If the condition occurred while reconnecting a disconnected REPO port, then verify the contactor of the
REPO connector pins.
For more information about the REPO port for an R12000DF power unit, see "Connecting the R12000DF
REPO port (on page 49)."
For more information about the REPO port for an R18000DF power unit, see "Connecting the R18000DF
REPO port (on page 54)."
UPS is in Bypass mode
Possible cause:
The equipment transferred to bypass utility power. Battery mode (on page 77) is not available and the
equipment is not protected; however, the utility power continues to be passively filtered by the power unit.
Action:
Check the UPS Event Log or the Management Module web interface for one of the following alarms:
• Extended overload
• Over temperature
• Output short
• Hardware failure
To attempt different resolutions, see "General alarm condition (on page 92)."
Overload condition
Possible cause: Power requirements exceed the UPS capacity. For output overload ranges, see "UPS output
specifications (on page 115)."
Action:
Remove one or more load devices to reduce the power requirements. The UPS continues to operate, but might
switch to Bypass mode (on page 77) if the load increases.
The alarm resets when the condition becomes inactive.
Troubleshooting 94
UPS is in Battery mode
Action: Save files, and then power down connected load devices.
UPS frequently switches between utility and battery
power
Action:
1. Check the input voltage, and then reconfigure the UPS menu options (on page 73).
2. Contact a qualified electrician to verify that the utility power is suitable for the UPS.
Battery fault
Action: If a battery fault occurs, replace the batteries.
UPS backup time is short
Action:
1. Verify that the battery pack circuit breakers are switched to the On position.
2. Verify that the life of the batteries did not exceed the limit.
3. If the condition persists, contact an HP authorized service representative.
Low battery shutdown
Possible cause:
An ungraceful shutdown of any attached servers occurs when the UPS is in a low battery condition.
Action:
1. Verify that the power management software is not delaying the shutdown of attached servers when the
UPS is in a low battery condition.
2. Allow the UPS batteries to charge for 24 hours.
Deep Sleep mode
To prevent battery modules from discharging when the charger is not available, the battery pack enters Deep
Sleep mode. Each cell displays Z V on the LCD screen. Deep Sleep mode occurs under the following
conditions:
• The UPS is in Bypass mode.
• The UPS charger limit is set to NO CHARGE and at least one battery module has a voltage of less than
36 V.
When these conditions are cleared and no battery module has a low voltage, the battery pack wakes up from
Deep Sleep mode automatically.
