Follow the steps in this section if you are replacing an existing, installed
EBM with a new EBM. If you are installing a new UPS or EBM, continue
to "Rack Installation and UPS Internal Battery Connection" on page 21.
NOTE DO NOT DISCONNECT the batteries while the UPS is in Battery mode.
An EBM can be replaced easily without turning the UPS off or
disconnecting the load.
If you prefer to remove input power to replace the EBM:
1. Press and hold the on/off button until the long beep ceases
(approximately 3 seconds), and then disconnect the UPS.
2. Wait 60 seconds while the internal processor shuts down before
you disconnect the EBM.
