Frequently Asked Questions

My unit is beeping twice every 15-45 seconds. What is happening?

This usually indicates that the unit is running on battery power. First, ensure that the unit is plugged correctly into the wall outlet. Second, check to see if the wall outlet is functioning properly by unplugging the CyberPower unit and plugging in a different device. If the other device is not working, there is a problem with the outlet and you should contact an electrician for repair. If the other device is working properly, try the CyberPower unit in a different outlet in the house and see if it yields the same results. If the unit is still producing the dual beeping noise, contact technical support for assistance.


What types of equipment are NOT allowed to be plugged into the UPS?

Any device which exceeds the unit's VA/Watt rating should not be plugged into the outlets. High drain devices, medical equipment, and aquatic equipment also void the unit's warranty. Below is a list of other devices that also void the warranty.

  • Laser printers
  • Space heaters
  • Copiers
  • Paper shredders
  • Vacuums
  • Curling irons

Can I use a different software package to manage my UPS?

CyberPower UPS systems will not work with other UPS manufacturers' software, but many models do support OS supplied management (e.g. Vista, XP, OS X).


Do I need to install PowerPanel software for my UPS to work properly?

PowerPanel software is not required for the UPS to provide surge suppression and battery backup. However, installing the PowerPanel software provides additional features and control for the UPS, along with the ability to automatically shut down your computer in event of a power outage.


What operating systems support USB connectivity with CyberPower UPS units?

The USB port can be used with Windows, 2000, XP, Server 2003, Vista, 7, and Server 2008.


Why does my UPS beep twice when I turn it on?

This is normal operation of the UPS. All CyberPower units perform a self-test routine when they are turned on.


Where is the serial number located on the unit?

The serial number is located on a white label adhered to the unit. The serial number is shown directly underneath the barcode.


What is the difference between the Battery/Surge outlets and the Surge outlets?

Many CyberPower UPS units have two sets of outlets. One set is labeled "Battery/Surge" and one set is labeled "Surge". The outlets labeled "Battery/Surge" are the outlets that will receive battery power during a power failure. You should plug your computer and monitor into these outlets and any externally powered critical data storage device.

Items such as printers, speakers, scanners, and faxes should be plugged into the outlets labeled "Surge." These outlets are intended for low priority electronics that are not essential to the PC's main operation.


Can I increase the runtime by hooking up multiple UPS units in a row?

No. This configuration is called daisy-chaining and will void the UPS warranty.


Can I hook up a surge strip to the UPS unit?

Surge strips cannot be installed before OR after the UPS unit. Doing so will void the UPS' warranty. If you require additional units, please upgrade your UPS to a unit that has more outlets.


Why am I not getting any power from the Battery/Surge outlets, only the Surge outlets?

Most of the time this is due to a malfunctioning/dead battery. Feel free to contact our technical support specialists, and they will properly diagnose the problem for you.


Why is the wiring fault light illuminated on my UPS unit?

The wiring fault light indicates that the outlet that the unit is connected to is either not properly grounded or has reversed wiring. First, try connecting the unit to another outlet. If the unit still displays the electrical wiring fault, contact technical support for assistance.

If the unit does not display the wiring fault light in the new outlet, you will need to have an electrician correct the problem with the faulty outlet.


Why can I not get a dial tone through the communication protection ports of my CyberPower UPS?

First, check to see that the phone cord is securely connected to the UPS and the computer. Next, check to see if you can get a dial tone when you bypass the unit. If you are able to get a dial tone when bypassing the unit, please contact technical support. If you are unable to get a dial tone when bypassing the communication protection ports, please contact your phone company.


My unit emits a long solid beep. What should I do?

A long, solid tone indicates that you have overloaded your unit. First, move any low priority electronics (speakers, printers, scanners, etc.) to the Surge-Only outlets and see if that resolves the issue. If you are still overloading the unit, you will either need to remove some of the electronics from the Battery/Surge outlets, or purchase a new unit with a VA/Watt rating suitable for your current demands.


How do I run a self-test?

To run a self-test, open the Power Panel software and then click "Initiate Self Test". Another way to perform a self-test is by turning off the circuit breaker for the circuit the UPS is plugged into or unplugging the unit from the wall.


My LCD screen shuts off after 15-30 seconds of inactivity. Is there a way to keep the LCD screen illuminated at all times?

The LCD will only light up when the Display button is pressed. This extends the life of the LCD screen and is part of the energy-saving features of CyberPower UPS systems.


Can I use my UPS in conjunction with a generator?

CyberPower Smart App Online Series UPS systems include a Generator Mode setting specifically designed to work with generators. With varying loads, the frequency output from generators can be erratic. This erratic output can make it difficult for a UPS without a Generator Mode setting to recognize the input power, causing the UPS to function on battery power only. With Generator Mode, the UPS can automatically adjust to frequency fluctuations and maintain a full charge of the batteries.


Should the cooling fan on my CyberPower UPS be running at all times?

The internal cooling fan will only run when it is required. CyberPower UPS systems utilize an internal thermometer which activates the fan when the temperature exceeds a certain threshold. When the UPS is running idle (not using battery power), it is completely normal for the fan to not be running. The exception is with Online units, models that begin with "OL". Their cooling fans will run ALL the time.


Do I have to have the UPS turned on in order for it to charge?

The UPS will charge the battery whether the unit is turned on or turned off.


Are the rackmount ears strong enough to hold up my rackmounted UPS? Does it also need to have rear supports?

The front-mount rackmount ears are specifically designed and tested to hold up their own weight in both a two-post and four-post rack enclosure. Rear supports are not needed, but users can install them if they wish.


How do I dispose of my UPS?

CyberPower Systems encourages environmentally sound methods for disposal and recycling of its UPS products. Please dispose of and/or recycle your UPS and batteries in accordance to the local regulations of your state.

If my surge protector has a ground light, should it be illuminated (green)?

Yes. The ground indicator light should be illuminated. If the light is not illuminated, there is a problem with the AC outlet into which the CyberPower surge suppressor is plugged. If this is the case, please disconnect the surge suppressor until the problem is resolved. The problem must be resolved before the CyberPower surge suppressor can be used.

Common issues with an AC outlet include: bad ground, missed ground, or reversed wiring (usually due to sub-standard wiring, typical in residential housing built prior to 1980). You may need to contact a qualified electrician to repair/upgrade the outlet.

NOTE: Using the CyberPower surge suppressor when the ground indicator light is not illuminated will void the warranty.


If my surge protector has a surge light, should it be illuminated?

Yes. The surge light should be illuminated. This indicates that the CyberPower surge suppressor is functioning properly. If the light is not illuminated, it indicates that the surge protector has received a catastrophic surge and will need to be replaced. CyberPower will replace the surge suppressor free of charge, provided the warranty terms and conditions are met.


How do I correctly use the IN and OUT jacks for RJ11/45 phone/network ports?

To correctly use the IN and OUT jacks for the RJ11/45 phone/network ports:

  • Connect the cord from your wall to the IN jack. NOTE: For some surge suppressors, the IN jack might show the icon of a phone.
  • Connect your computer or peripheral to the OUT jack. NOTE: For some surge suppressors, the OUT jack might show the icon of a computer.

What types of electronics are intended to be plugged into transformer outlets?

The transformer outlets are spaced farther apart than the other outlets to accommodate transformer block adapters or any other adapters that are large in size. Transformer outlets can be used to connect any appropriate device to the surge suppressor.

The circuit breaker on the PDU is tripping but it is not overloaded. What could be the problem?

High operating temperatures can also cause the circuit breaker to trip. Check that the ambient temperature where the PDU is installed is within the specified range.

Yes, select PDU models include keyhole mounting pegs. If you received a PDU User Manual, please see it for details.


Can a PDU also monitor temperature and humidity?

Yes, with the optional EnviroSensor installed and connected. The EnviroSensor will monitor ambient temperature and humidity and report that information to the PDU.


Can the PDU be configured to shutdown individual outlets?

Yes, switched PDU models can be configured via the web management interface.


The PDU I have has two outlet banks but only 1 display. What is the display reading?

Metered, monitored, and switched PDU models display the total current being drawn by the connected equipment on the screen. If there are two outlet banks, then the display is showing the total aggregate current draw between both banks.


Can computers be configured to automatically shutdown with a PDU?

Yes, PowerPanel Business Edition can be installed on a computer to configure unattended shutdown settings. For details, please see the PowerPanel Business Edition User Manual.


Do any of the CyberPower PDUs have an on/off switch?

No. None of the PDUs will have on/off switches on them. All CyberPower PDUs are always on by design.


Do PDUs have surge protection built in?

No, PDUs do not have surge protection. If you are looking for a power distribution unit with surge protection, look at CyberPower's line of Rackbars.


Can I plug a 120V device into a PDU30MVHVT20F?

No, PDUs with a model number that includes "HV" indicate it is for High Voltage and will only support 200V-240V input and output.


The Amperage displayed on Amperage Meter exceeds the unit's capability (Metered type only). What does this mean?

The meter will flash when overloaded. Reduce the load on the PDU until the overload is gone. If the problem remains, contact technical support.

What is a hot-swappable battery?

A hot-swappable battery eliminates power-related downtime and ensures maximum power availability. All potential UPS maintenance, including complete power module exchange, can be performed without powering down connected equipment. As long as utility power is on, you may leave the UPS and connected equipment on while replacing a new battery.


What is Cold Start Functionality?

Cold Start Functionality restores emergency power to the load after the installation of a new battery.


What should I do with spent batteries?

Should the power inverter beep when I turn it on?

Yes. All CyberPower power inverters will beep when they are turned on or restarted.


Why does my device periodically beep twice?

This is due to overloading or underpowering. Overloading is caused by an excessive load and can be resolved by either upgrading to larger power inverter or by reducing the load of the attached equipment. If the device is underpowered, connect it to power source that is outputting greater than 11 volts. Most often, users simply need to start their vehicle and recharge the battery.


Why does my unit emit a long solid beep or a series of rapid beeps?

This is due to overloading the unit. You will need to reduce the load placed on the unit or purchase a larger unit.


I am having problems getting the device to work on airplanes. How can I resolve this issue?

Many airlines limit in-seat power to a maximum of 75 watts. (Most laptops require >100 watts.) The recommended workaround is to remove the battery from the laptop. Doing so should reduce the power demands of the laptop to under 75 watts because the battery will no longer be charging while the laptop is in use.

What is Cat 5 (Cat5)?

Category 5 cable (Cat 5 or Cat5) is a twisted pair cable for carrying signals. This type of cable is used in structured cabling for computer networks such as Ethernet. The cable standard provides performance of up to 100 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), and 1000BASE-T (Gigabit Ethernet). Cat 5 is also used to carry other signals such as telephony and video.


What about Category 5 vs. Category 5e?

Category 5 has been superseded by the Category 5e (enhanced) specification. The Category 5e specification improves upon the Category 5 specification by tightening some crosstalk specifications and introducing new crosstalk specifications that were not present in the original category 5 specification. The bandwidth of category 5 and 5e is the same: 100 MHz.


What is Cat 6 (Cat6)?

Category 6 cable, commonly referred to as Cat 6 (Cat6), is a standardized cable for Gigabit Ethernet and other network physical layers. It is backward compatible with the Category 5/5e cable standards.

Compared with Cat 5 and Cat 5e, Cat 6 features more protection for crosstalk and system noise. The Cat 6 cable standard also provides performance of up to 250 MHz and is suitable for 10BASE-T, 100BASE-TX (Fast Ethernet), 1000BASE-T/1000BASE-TX (Gigabit Ethernet), and 10GBASE-T (10-Gigabit Ethernet).

Category 6 cable can be identified by the printing on the side of the cable.


What is Firewire?

Firewire or FireWire® Cable is also known as IEEE 1394. The original release of IEEE 1394-1995 is now known as Firewire 400. It can transfer data between devices at 100, 200, or 400 Mbit/s. The cable's maximum length is limited to 14.8 ft. (4.5 meters), but you can have up to 16 cables daisy-chained by using active repeaters, external hubs, or internal hubs.
