26 Reconfigure your library settings as they were before.
Adding, Removing, and Replacing Power Supplies
Library power is controlled at the individual power supplies and at the
front panel of the library. The switch on the rear of each power supply
shuts down power at the input of the individual power supplies. The
switch on the front of the 5U Library Control Module provides power to
all 5U Library Control Module and 9U Expansion Module power
supplies. You can also turn off library power using the Web client, if
necessary.
Adding a Redundant
Power Supply
12
These instructions explain how to add a second (redundant) power
supply to a module. You may need to add a redundant power supply to
the library to make sure that the library does not go down (and become
inaccessible) if its original power supply happens to fail. The library
automatically uses the redundant power supply if the first power supply
fails for any reason.
Caution: Contact Dell Support before restoring the
configuration. In general, it is recommended that you
use the setup wizard to manually reconfigure the
library. It is not recommended to use the “restore
configuration” tool to restore the previous settings.
Doing so will completely reinstall the former library
firmware level and potentially any defective
configuration settings encountered prior to installing
the new LCB/compact flash card combo. If you do
restore a previous configuration and downrev
firmware, you will need to install the latest version of
firmware again.
