Power Specifications
This section lists power specifications for tape drives.
Rack Mount Tape Drive Power Specifications
TABLE E-3
lists the input power and current requirement for each tape drive power
supply in the rack mount assembly under nominal conditions at various input voltages.
Nominal conditions occurring when the tape drive is moving tape in read/write and
rewind modes.
Note – The tape drive draws the same power from the power supply regardless of the
AC input voltage.
For the purposes of figuring the amount of heat generated by a tape drive and its
associated power supply, use the figure of 172.3 watts, which converts to approximately
588 Btu/hr. Because there are usually two tape drives in a rack mount unit, these
figures are doubled for a complete rack mounted pair of tape drives, or 244.6 watts,
which converts to 1,176 Btu/hr.
Library-attached Tape Drive Power Specifications
For SL3000 and SL8500 libraries, use the power figure of 100 watts for each tape drive
and its associated power supply and use a heat figure of 341.29 Btu/hr.
For other libraries, use the power specifications for a single rack mount tape drive and
power supply. In those libraries, there is one AC/DC power supply for each tape drive.
