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)
, and
“Powering on the library” (page 104)
. The blue LED on the power supply
will be on and not blinking.
