the second is Slot 1, etc.
Power Supplies
MSL Series tape libraries support one or two power supplies that are accessible
from the rear of the unit (see Figure 4). These auto-ranging power supplies are
capable of using any nominal AC voltage between 100 VAC and 240 VAC power,
at 50 Hz or 60 Hz, and are easily removed without requiring special tools.
Power to the library is supplied through AC connectors at the rear panel of each
power supply receiver. Library power is normally controlled from the graphical
user interface (GUI) touch screen; however, a manual power disconnect switch is
located at the rear of each power supply.
Caution: The power supply is generally not to be removed by the operator.
Hazardous voltage is present in the cavity if the power cord is not removed. If
a faulty power supply exists, contact your authorized service provider.
For the four-drive models, two power supplies are supported to provide
redundancy for mission critical operations. Both power supplies share the load
under normal operating conditions, but if one of the power supplies fails, the
remaining power supply assumes the full load (see Figure 4 on page 29).
