Power Configurations
1-14 StorageTek SL3000 Library Guide
The number of drive DC supplies that must be ordered depends on the power
configuration selected. For instance, if the example library had a 2N+1 configuration, it
would require an order of six additional drive DC power supplies (four supplies for
the Base module and two supplies for the DEM). The 2N+1 also requires an additional
DC supply for the robotics and an additional ECM 200W cPCI power supply. The ECM
power supply is different than the tape drive and robot power supplies listed in this
example. For ordering information, see
"DC Power Supplies" on page 1-28.
AC Power Cables
The following table lists the cables required for each power configuration. You must
order one power cord per PDU installed:
■
N+1 — order one power cord for the Base module and an additional power cord
for the DEM (if installed)
■
2N or 2N+1 — two power cords for the Base module and two additional power
cords for the DEM (if installed)
Power Consumption
For environmental or economical reasons, you might want to determine the total
power consumption (watts), CO
2
emission values, and British Thermal Units (Btu/hr)
for the SL3000 library and tape drives. The table below provides power consumption
in watts.
