About the CX200-Series DPE2
Drive Carrier
The disk drive carrier is a metal and plastic assembly that provides
smooth, reliable contact with the enclosure slot guides and midplane
connectors. It has a handle with a latch and spring clips. The latch
holds the disk module in place to ensure proper connection with the
midplane. Disk drive Activity/Fault LEDs are integrated into the
carrier.
Drive modules are extremely sensitive electronic components. Refer to the
instructions on Handling FRUs and Replacing or Adding a Disk Module in
Chapter 3 whenever you handle a disk module.
Power Supply/System Cooling Modules
The power supply/system cooling (power/cooling) modules are
located above the SPs. The units integrate independent power supply
and dual-blower cooling assemblies into a single module. CX200LC
enclosures use one power\cooling assembly and a blower-only
module that includes dual blowers but no 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 DPE2 and shares
load currents with the other supply. The drives and SPs have
individual soft-start switches that protect the disk drives and SPs if
you install them while the disk enclosure is powered up. A FRU
(disk, SP, blower, or power/cooling module) with power-related
faults will not adversely affect the operation of any other FRU.
The system cooling assembly includes two dual-blower modules. If
one blower fails, the others will speed up to compensate. If two
blowers in a system (both in one power/cooling or blower module,
or one in each module) fail, the CX200 will go off line within two
minutes.
Each power/cooling module has visible status lights. The rightmost
LED indicates power to the supply; the LED adjacent to it indicates a
power supply fault. The leftmost LED (the single LED in a CX200LC
blower module) indicates a failure in one of the integrated blowers
within that module. The status lights are described in Monitoring
CX200-Series Status in Chapter 3.
Figure 1-9 shows a rear view of a CX200 power/cooling module; note
that a CX200LC blower and power/cooling modules are externally
identical except the blower module includes none of the power
switch, connector, or LED components.
