Table 19 describes the DAE power supply/cooling module LEDs.
The power supply/cooling modules are located above the LCCs. The units integrate
independent power supply and blower cooling assemblies into a single module.
Each power supply is an auto-ranging, power-factor-corrected, multi-output, offline
converter with its own line cord. Each supply supports a fully configured DAE and shares
load currents with the other supply. The drives and LCCs have individual soft-start
switches that protect the disk drives and LCCs if they are installed while the disk enclosure
is powered up.
Note: Each line cord should be plugged into a different AC power distribution unit (PDU)
for high availability (the
VNXe3100 Installation Guide
provides more information).
DAE LCC input/output ports and connectors
The 2U, 12 (3.5-inch) DAE LCC supports two 6-Gb/s SAS x 4 ports on the rear of the device.
