Battery condition 
Action: 
1.  Install the battery module. If the battery module is already installed, remove and reinsert the module. 
2.  Allow the UPS batteries to charge for 48 hours. 
3.  If the LED does not turn off, replace the batteries ("UPS battery replacement procedure" on page 35). 
4.  If the condition persists, contact an HP authorized service representative. 
 
Bypass is out of range 
The input voltage is not within ±12 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 ("Configuring the UPS" on page 27). 
2.  Contact a qualified electrician to verify that the utility power is suitable for the UPS.
