Note that this does not completely remove library power (you need
to disconnect the power cords to do that).
• Disconnect the power cord from each power supply on the back of
the library. It may take 1 to 2 seconds for motion to completely
stop.
Caution: These methods are not recommended except in case of
emergency where it is vital that library operations be
stopped immediately. If you do not first perform a
shutdown as described in the sections above, 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.
– If you unplug the power cord, 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.
Some maintenance activities require that the entire library be taken
offline. To take the library offline, change the mode of all partitions from
online to offline. See
instructions.
The I/E station is locked during normal library operation. To access the 
I/E station you must first unlock it. When you give the command to
unlock the I/E station, the robot physically moves to the unlock
mechanism and unlocks it. This takes a few seconds. Once unlocked,
you have 30 seconds to open the I/E station before it locks again.
