o Standalone UPS configuration—See "Powering up the standalone UPS (on page 25)." o Parallel UPS configuration—See "Powering up the parallel system (on page 39)." Communication options The UPS has serial communication capabilities through the DB-9 communication port or through an X-Slot card in one of the available bays. The UPS supports two serial communication devices. NOTE: Relay, signal inputs, and the serial port baud rates are configurable through the front panel menus.
Pin number Signal name Function Direction from the UPS 4 — No connection — 5 GND Signal common (tied to chassis) — 6 — No connection — 7 — No connection — 8 — No connection — 9 — No connection — Control terminals The cables should be connected to the control terminal with a mating connector. Input and output terminals have a functional isolation from terminal to terminal. They are connected to the UPS chassis through individual 1 MW resistors.
The UPS incorporates a programmable relay output with potential free contacts for remote alarm indications. An additional four relay outputs can be obtained with the compatible Relay Interface option card. Programmable signal inputs The UPS incorporates two programmable signal inputs. HP recommends using non-polar (relay) control input. The pins must be shorted with maximum resistance of 10 ohm in order to activate the specific input. Verify control terminal connections if polarity control is required.
Mode transfers • If one UPS in a parallel system transfers from High Efficiency mode (on page 65) to Normal mode (on page 65), the other UPSs transfer also. • If one UPS transfers to Battery mode (on page 66), the remaining UPSs in the parallel system stay online. The transferred UPS might transfer back to online at any time, and the parallel system resynchronizes.
Metering The Output and Load Receptacle meter readings differ between a parallel system and a standalone UPS. In a parallel system, one UPS reads the Load Receptacle value for the total system (the others read zero), but each UPS displays its own Output value. For example, in a two-unit parallel system with one Anderson load connection for 12 kVA, the Load Receptacle current would read 12 kVA on one UPS and zero on the other UPS, but the Output measurement would be 6 kVA on each UPS (half the total).
Power management HP UPS Power Protection Agent overview The HP UPS Power Protection Agent runs on a local or network server and allows the management module to gracefully shut down the operating system of that server and optionally run a script during power failure. Install the agent on any machine that is powered by the UPS and any machine that the management module uses to initiate a command.

Troubleshooting LED and audible alarm troubleshooting This UPS is designed for durable, automatic operation and also alerts you whenever potential operating problems might occur. Usually the alarms shown on the control panel do not mean that the output power is affected. Instead, they are preventive alarms intended to alert you of a possible condition. The following table describes typical alarms and conditions.
On On—1 beep Overload every 3 seconds ("Overload condition" on page 98) On On—1 beep Overtemperature every 3 seconds ("Overtemperature condition" on page 98) On On—1 beep Site Wiring Fault every 3 seconds ("Site wiring condition" on page 99) For the location of individual LEDs, see "UPS front panel LED indicators (on page 9)." Silencing an audible alarm To silence an alarm, press any button on the front panel display to silence the alarm.
Action: 1. Be sure that the UPS battery circuit breaker is in the On position. 2. If the condition persists, contact an HP authorized service representative. Battery connection condition Possible cause: • The UPS does not recognize the internal batteries. • Two or more battery trays are disconnected. Action: 1. Be sure that all the battery trays are fully seated and locked in place. 2. If the condition persists, contact an HP authorized service representative.
1. Verify the bypass utility. 2. Check for one of the following alarms: o Bypass over or under voltage o Bypass over or under frequency o Bypass unavailable Check Parallel Board condition Possible cause: The UPS does not recognize another paralleled UPS. Action: 1. From the UPS Status menu, select the Units on Parallel Card option and be sure that all UPSs appear in the list. 2. If any UPS is missing, verify the Parallel UPS Card connections and recheck the status from the UPS front panel.
4. To supply power to the connected equipment, power up the UPS. o Standalone UPS configuration—See "Powering up the standalone UPS (on page 25)." o Parallel UPS configuration—See "Powering up the parallel system (on page 39)." Protected equipment is not on Possible cause: The UPS is operating normally, but some or all of the protected equipment is not on. Action: • Be sure that the equipment is plugged into the UPS receptacles. • Be sure that the output circuit breaker is in the Off position.
Remove one or more load devices to reduce the power requirements. Selective trip Possible cause: The UPS detected an internal fault. Action: If the condition persists, contact an HP authorized service representative. Site wiring condition Action: Contact a qualified electrician to be sure that: • The line and neutral wires are not reversed in the wall outlet. • A ground wire connection does not exist.
o 6. Parallel UPS configuration—See "Powering up the parallel system (on page 39)." Contact a qualified electrician to check the power cord connections. UPS does not provide the expected backup time Action: 1. Be sure that the battery circuit breakers are in the On position. 2. Allow the UPS batteries to charge for 48 hours. 3. If the condition persists, contact an HP authorized service representative. UPS does not transfer to Auto-Bypass mode Action: • Verify the bypass utility.
