v Update drive firmware (see "Updating Drive Firmware"
on page 8-13.
v Update library firmware (see "Updating Library
Firmware" on page 8-12.
v If the problem still exists, replace the drive sled (see
"Adding/Removing/Replacing a Drive Sled" on page
12-15).
The library can no longer detect the presence of a power
supply that was previously physically installed and
logically added to the system.
Regular polling between LCB and power supply checks for
presence of the power supply.
1. Power Supply has been physically removed after being
added to a powered ON system.
2. Hardware failure inside supply
3. Hardware failure in library side connector of other
electronics.
