3.6 Power cabling
Connecting the power cables to DS3000 subsystems and EXP3000 enclosures is a simple
task. Each of the two power supplies has a power cord connector. You simply have to connect
each power supply to a power source. For increased protection in case of power loss,
consider connecting each power supply to a different power source.
3.7 Powering on and off
A typical DS3000 configuration includes the following components:
Host servers
DS3000 storage subsystem
EXP3000 enclosures
(Optional) SAN infrastructure
Host server 1
Host server 2
Host server 3
DS3400

Attention: Make sure the power switch on each power supply is in the Off position before
attaching the power cable.
