HP DirectFlow UPS overview

The HP DirectFlow UPS features a configurable rack-mount design that offers three-phase power protection for loads up to a maximum of 20000 VA/18000 W (these numbers might vary by model). Features include:

- Configurations for extending runtime

- A configurable power unit with the following rack unit heights:

R12000DF—1U

R18000DF-2U

• Optional 3U lead acid or 1U lithium-ion battery packs. 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

• Warning before the end of the useful battery life
• 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

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

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.

1. Select Charger Limit-Gen, scroll to the wattage, and then press Enter. The default charger limit wattage setting is 0 W.
2. Select Charger Limit-Uti, scroll to the wattage, and then press Enter. The default charger limit wattage setting is 555 W.
3. 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 becoming 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) • Bypass mode (on page 77)

AC mode

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.

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.

Maintenance

Updating the UPS firmware

Download the HP DirectFlow Upgrade Utility (Upgrade_HP_v00_1b_b11282013.exe) from the HP website (http://www.hp.com/go/rackandpower).

To update the UPS firmware:

1. From AC mode, move the CAM switch on the power module to the Bypass setting.
2. Connect a local host computer or device to the power unit serial communications port. For more information, see either "Connecting the R12000DF serial communications port (on page 50)" or "Connecting the R18000DF serial communications port (on page 55)."
3. Launch the utility.
4. Click Upgrade Now.

If you receive an error, verify the UPS is in Bypass mode.

During upgrade, the utility:

• Verifies communication between the power unit and host computer or device
• Sets the UPS in Bypass mode for the upgrade process
• Flashes each component individually in order
• Displays a progress line
• From Bypass mode, move the CAM switch on the power module to the AC setting.

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: While testing, operate connected equipment in a safe test mode so the effects do not disrupt critical operations.

Verify the connection after connecting the REPO port:

1. Initiate a REPO by closing the REPO contact.

CAUTION: If the polarity is reversed while connecting the REPO port, the UPS powers up normally.

1. Verify proper connection of the REPO port:

a. Press the On button to power up the UPS. b. Disconnect the REPO port. c. Reconnect the REPO port. If the polarity is correct, the REPO connectors can be disconnected, and then reconnected, without initiating a REPO. d. Verify that the UPS remains in AC mode (on page 76). e. If a REPO is initiated, the polarity is reversed. Check and correct the connections.

Powering down the UPS and battery packs

To power down the UPS:

1. Power down all load devices.
2. Press the ESC button for 3 seconds, and then press the Enter button to place the UPS in Bypass mode.
3. Disconnect the power unit from utility power.

3. 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.

• 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)."

Electrostatic discharge

Preventing electrostatic discharge

To prevent damaging the system, be aware of the precautions you need to follow when setting up the system or handling parts. A discharge of static electricity from a finger or other conductor may damage system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the device.

To prevent electrostatic damage:

• Avoid hand contact by transporting and storing products in static-safe containers.
• Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations.
• Place parts on a grounded surface before removing them from their containers.
• Avoid touching pins, leads, or circuitry. Always be properly grounded when touching a static-sensitive component or assembly.

Grounding methods to prevent electrostatic discharge

Several methods are used for grounding. Use one or more of the following methods when handling or installing electrostatic-sensitive parts:

• Use a wrist strap connected by a ground cord to a grounded workstation or computer chassis. Wrist straps are flexible straps with a minimum of 1 megohm ±10 percent resistance in the ground cords. To provide proper ground, wear the strap snug against the skin.
• Use heel straps, toe straps, or boot straps at standing workstations. Wear the straps on both feet when standing on conductive floors or dissipating floor mats. Use conductive field service tools. Use a portable field service kit with a folding static-dissipating work mat.

If you do not have any of the suggested equipment for proper grounding, have an authorized reseller install the part.

For more information on static electricity or assistance with product installation, contact an authorized reseller.
