About the Rackmount Disk-Array Processor Enclosure
within the same DPE, subject to the restrictions imposed by the Core
Software running in the DPE’s SPs.
Drive Carrier
The disk-drive carrier is a plastic assembly that slides into the
enclosure slot guides and midplane connectors. It has a handle with a
latch and electrostatic discharge (ESD) clips, which connect to the
drive’s head-disk assembly. The latch holds the disk module in place
to ensure proper connection with the midplane.
Power Supplies
The power supplies (see figure below) are located behind the drive
fan pack. With two power supplies, the top supply is installed
inverted with respect to the bottom supply.
Figure 1-10 Power Supply
Each power supply is an auto-ranging, power-factor-corrected,
multi-output, off-line converter with its own line cord and on/off
switch. Each supply supports a fully configured DPE and shares load
currents with the other supply, if it is present. The drive and LCC
voltage lines have individual soft-start switches that protect the disk
drives and LCCs if you install them while the DPE is powered up. A
CRU with power-related faults will not adversely affect the operation
of any other CRU.
