About DAE2 Disk Enclosures
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.
Power Supply/System Cooling Modules
The power supply/system cooling (power/cooling) modules are
located above the LCCs. The units integrate independent power
supply and dual-blower cooling assemblies into a single module.
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 DAE2 and shares
load currents with the other supply. The drives and LCC have
individual soft-start switches that protect the disk drives and LCCs if
you install them while the disk enclosure is powered up. A FRU
(disk, LCC, or power/cooling module) with power-related faults will
not adversely affect the operation of any other FRU.
The enclosure cooling system 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 module, or one in
each module) fail, the DAE2 will go off line within two minutes.
Each power/cooling module has three visible status lights. The
rightmost LED indicates power to the supply; the LED adjacent to it
indicates a power supply fault. The leftmost LED indicates a failure
in one of the integrated blowers within that module that cool the disk
enclosure. The status lights are shown in Figure 1-8 and described in
Monitoring Disk Enclosure Status in Chapter 3.

Power/Cooling Module
A latch on the power/cooling module locks it into place to ensure
proper connection to the midplane. You can add or remove one
power/cooling module in a DAE2 while the system is powered up.
