HP MSL6000 manual Power Supplies, Library power supplies

Power Supplies

MSL Series tape libraries support one or two power supplies depending upon the model (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.

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 22). For the two-drive models, only one power supply is supported.
