Installation

Preparation

Before installing the disk system, make sure (1) electrical wiring, breakers, and

PDUs meet power needs, (2) the required support software is installed on the

host, and (3) if you are connecting the disk system to a V-class server, auto-

termination is enabled on the host bus adapter. This section covers all three of

these topics.

Electrical Requirements

All electrical wiring to the service point (plug) must be sized to carry the

appropriate inrush (20 amps per power supply) and steady state currents. See the

following table for examples.
