DC-Powered VNX™ Series Enclosures
Installation and Operation Guide
P/N 300-012-880
Rev 03
April 11, 2014
Power considerations ......................................................................................... 2
Cabling DC power and powering the system up and down .................................. 8
Installing a DC-AC inverter ................................................................................ 13
DC power supplies in the VNX5100, VNX5300, and VNX5500 disk processor
enclosures (DPE) and DAE6S disk array enclosures include power on/off switches
or buttons.
DC storage systems do not include standby power supplies (SPS).
DC storage systems that support file I/O include 1U DC-AC inverters for the control
stations.
• In VNX5100, VNX5300, and VNX5500 systems, the inverters occupy the
physical space reserved for an AC SPS.
• VNX5200, VNX5400, and VNX5600 systems install the inverters directly above
the control stations.
