Completely Removing Library Power

Completely removing library power means disconnecting the power
cord from each power supply on the library.
Caution: You should always perform a shutdown and then turn off
library power before completely removing power.
Otherwise, the following could occur:
– The library may not complete closing all data and log
files.
– If you turn off power or unplug the power cord while
writing to tape, the data on the tape could become
corrupted.
– The robot may become frozen in the middle of an
operation and unable to move once library power is
restored, possibly requiring a service call.
1 Make sure the connected host applications are not sending
commands to the library and that all library operations have
stopped.
2 Shut down the library (see
3 Turn OFF the library by physically pressing the power button on the
library's front panel (see
sure the operator panel turns off or the LED on the SCB turns off.
4 Disconnect the power cord(s) from all power supplies on the back of
the library. If there are two power supplies, disconnect both cords.
Power is completely removed from the library when the LED on each
power supply is off.
In an emergency, you may need to turn off power immediately to stop
robot motion, bypassing the normal shutdown process.
In an emergency, you can turn off power in one of two ways:
• Press the power button on the front of the library to turn the library
OFF. It may take up to 4 seconds for all motion to completely stop.
