Replace your batteries ASAP

Bypass failure is the same as your input unless you have a dual input. You lost power and the UPS did not hold the load because the batteries are bad. Replace the batteries and you will be ok.

First calculate the total load of the UPS and then calculate the total load. One of the Intel Module is Primary and one is Secondary. I can't remember exactly which one is primary. Q1. There will be a LED on the INTELI MODULE flashing RED. That identifies the bad MODULE. Q2. You can remove the MODULE, but I recommend you place the UPS in Static Bypass first through the Display Menu. Also make sure the UPS is in NORMAL MODE or already in STATIC BYPASS, the LED's on the Display should indicate what mode its in. Q3. You can remove the display from the Inteli Module with out harming the load. You just can't do anything with the UPS, as to tell it to Go to Bypass (Static Bypass) or get out of Bypass, check voltages, etc. So order the part first by getting part number on the sticker off the Module, then schedule your shutdown and perform the you maintenance after hours this way you don't affect anything during business. Also don't do the repair on a Friday due to the fact its weekend and APC/Third party UPS companies will charge you a lot to come out in the weekends. FIRST DO THIS PLEASE- GET THE MANUAL FOR THIS UNIT!!!! And READ IT FIRST!! Find in the manual where it walks you through putting the UPS In bypass (Static Bypass). Follow the manual, My way of doing is to READ TWICE, OPERATE UPS ONCE!! This has help me not dump any loads. My suggestion to you is to check if unit is in Bypass (static Bypass due to the faulty module. If it is on Bypass then all you need to do is follow the procedures to place UPS in External Maintenance Bypass. If UPS is in Normal mode but with Alarms and Beeping, then Navigate through the display and find the BYPASS Mode. Then hit enter Yes on the BYPASS MODE, it will ask you again if you want to "Place UPS INTO BYPASS. Hit YES. You will hear it click. Your LED on the display should Light UPS Solid "BYPASS LED ON" AGAIN Please keep referring to the MANUAL. Once your in bypass mode (Static Bypass) then you can operate the External Bypass Switch on the bottom of the UPS. That is the Maintenance Bypass Switch. This isolate the UPS completely and your load never see's the transfer from Static Bypass to External Bypass, Because its a MAKE BEFORE BREAK System. (Make the power before Breaking the Power) Sorry to get down to simple terms, but when I work on a UPS its personal due to the fact you are responsible for the all that is on the OUTPUT of that UPS. Once on External Bypass, You can now do you module swap. Turning the UPS back on, Please follow place UPS back On Line in the UPS Manual. Also in the Diagnostics, off the display of the unit, it also identifies what module is bad including the Power Modules to the Battery Modules.

Have you tried the user manual? eaton.com/9155 will take you to the product page on the website. 800 843 9433 is the tech support number. Or you can email [email protected]

a red alarm on a ups normally means the batteries are dead. you will need to order and replace the batteries in the UPS.

Thanks

You definitely want to follow the manual procedure to avoid a possible load loss:

9.1.4 Transfer from Normal to Bypass Mode
To transfer the critical load to Bypass mode:
C A U T I O N
In Bypass mode, the critical load is not protected from commercial power interruptions and abnormalities.
1. Press the CONTROLS pushbutton on the main menu bar. The System Controls
screen appears.
2. Press the BYPASS pushbutton on the System Controls menu bar.
The UPS transfers to Bypass mode and the critical load is immediately supplied
by the bypass source. If the bypass source is not available, the power processor
remains on and an alarm sounds.
3. The UPS is now operating in Bypass mode and the BYPASS status indicator is
illuminated.
The power module (PM) status indicates READY. The system is now on bypass
and the UPS power processor remains on.


At this point, you can operate an external bypass switch to get to maintenance bypass if needed.

Advanced Battery Management Technology Prevents Premature Failure and Significantly Extends Battery Service Life
Batteries are the most critical component in the reliability of any UPS, but they face three fundamental challenges: All Batteries Need Charging
But extended charging significantly shortens battery life. Most batteries are charged with a trickle-charging process (a constant voltage feeding a low current to the battery). This method dries the electrolyte and corrodes the plates, reducing potential life by up to 50%.
Batteries Take Time To Recharge
Users can’t wait. During prolonged power outages, the UPS batteries will discharge and not recharge until the power returns. When there is a subsequent power failure before the batteries recharge, the computer will not have full backup time. Overly rapid charging can cause premature battery failure, so the trick is to charge at the fastest rate that is safe for the battery.


All Batteries Will Eventually Fail
The question isn’t “Will it happen?” but “When will it happen?” Because UPS batteries are valve-regulated, sealed lead acid, there has previously been no practical way to provide the user with any meaningful advance notice that batteries need to be replaced. In the past, the only way to know when the batteries were dead was when the power failed and took your computer down with it. Until now, typical UPS batteries have required replacement every two to three years.
Our exclusive ABM technology solves these UPS battery problems. It significantly increases the life of UPS batteries (see Figure 1), provides the fastest safe recharge time, and provides reliable advanced notice when the batteries need replacement. By extending battery life and virtually eliminating this major cause of surprise load crashes, we are able to offer the industry’s longest and most inclusive warranties on all products that incorporate ABM. No other manufacturer can make this statement.
ABM technology is available on Powerware 5115, 5125, 9120, 9125, 9140, 9155, 9170+, 9355, and BladeUPS UPSs.
