Before You Start
IMPORTANT Be sure you have completed all of the following site
and configuration preparations before you attempt to set up your
DAE2s.
1. Confirm that electrical wiring to accommodate your cabinet’s
power cables is in place at your facility.
The standard 40U EMC cabinet includes two 240-volt ac power cables.
To support all of the DAE2 high-availability features, you must connect
each power outlet to a different circuit.
2. If you are connecting the DAE2 to a storage device such as a
CX-Series storage processor enclosure (SPE), make sure the
device is installed in the cabinet and set up. Refer to the Setup
Guide or Hardware Reference for the device.
3. If you will use EMC ControlCenter Navisphere Manager to
monitor DAE2 status, make sure that Navisphere Manager
version 6.1 or higher is set up. Refer to the EMC ControlCenter
Navisphere Manager Revision 6.X Administrator’s Guide and the
appropriate Release Notes as necessary.
4. If your DAE2 is not already installed in a cabinet, do so now. The
EMC Storage Systems 40U Cabinet Configuration Guide
describes how to install a 3U device like the DAE2 in EMC’s
standard cabinet.
You can add DAE2 enclosures to running storage systems without
powering down the existing system.
