What do I do if I lose power during a backup? If your library contains a redundant power supply,
it is unlikely that power will ever be completely unavailable to the library.
The library should recover even if power goes out completely during a backup. If power remains
off, press the Power button, and leave it in the off position until you can obtain a reliable power
source. When the power to the library is turned back on, the library will recover. You must re-run
the backup using your application software.
If the library does not automatically come back up after a power outage, cycle library power.
Cycling library power involves shutting down the library, powering it off, and then powering it on.
For more information, see “Shutting down/rebooting the library” (page 101), “Powering off the
library” (page 104), and “Powering on the library” (page 104). The blue LED on the power supply
will be on and not blinking.
