Power Configurations
Library Overview
1-11
Electronics Control Module Power Supplies
The electronics control module (ECM) uses 200 W cPCI power supplies. These power
supplies are located below the HBT card in the Base module (there are no ECM power
supplies in the DEM) — see
. The power supply for the electronics control
module is different from the power supplies used for the robotics unit and the tape
drives.
Each Base module ships standard with two ECM power supplies used for N+1 and 2N
configurations. Order two additional ECM supplies for the 2N+1 configuration (see
Robotics Unit Power Supplies
The robotics unit uses load-sharing 1200 W DC power supplies located at the top of
the Base module (the DEM does not contain robotics DC supplies) — see
The 1200 W DC power supply used for the robotics unit is the same power supply
used for the tape drives.
Each Base module ships standard with two robotics DC power supplies used for N+1
and 2N configurations. Order a third DC power supply for the 2N+1 configuration
(see
Tape Drive Power Supplies
The tape drives use load-sharing 1200 W DC power supplies. Up to four tape drive
power supplies are located to the left of each PDU in both the Base module and the
DEM — see
.
The library ships with two tape drive DC power supplies per Base module and two
tape drive DC power supplies per DEM. The number of tape drive DC power supplies
required depends on the power configuration selected and the number and type of
tape drives in the library. To calculate the number of power supplies to order, see
"Calculating Tape Drive Power Supply Quantities"
Calculating Tape Drive Power Supply Quantities
The number of power supplies required depends on:
■
Power configuration (120 VAC or 240 VAC with N+1, 2N, or 2N+1)
■
Number and type of tape drive (T10000, T9840, or LTO)
To determine the number of power supplies required for a library configuration:
1.
Determine the total number of each drive type.
2.
Multiply by the watts-per-drive for each drive type, see
.
3.
Add together the watts used by each drive type to calculate the total watts
consumed.
4.
Use
through
to determine the number of DC power supplies
needed.
