116 EMC VNX5400 Hardware Information Guide
Disk-array enclosures
In the 4U, 60 (2.5- or 3.5-inch) DAE, the power supplies provide four independent power
zones. Each of the hot-swappable power supplies has the capability to deliver 1300 W at
12 V in its load-sharing highly-available configuration. Control and status are
implemented throughout the I
2
C interface.
Figure 95 shows an example of the 4U, 60 (2.5- or 3.5-inch) DAE AC power supply with two
power in recessed connectors (or plugs) and status LEDs.
