Connecting Power Cords

Description
Connecting Power Cords
You should connect power cords to all ac power connectors (see Figure 3). Disk array availability is
enhanced if each power cord is connected to a separate ac branch circuit.
WARNING! To avoid a fire hazard, the ac branch service must be properly current-
protected by either a fuse or a circuit breaker. Use only UL/CSA approved power cord, SVT
type, rated for suitable voltage and current. These power cords have two conductors and a
ground. Failure to use the proper power cord may result in a shock or fire hazard.
Installing Modules
This chapter shows how to install modules into the disk array.
NOTE! To improve enclosure cooling and balance the load on the internal SCSI buses, the disk
modules should be installed from left to right and from top to bottom. Disk module SCSI
addresses are automatically preset by the backplane inside the disk array enclosure upon
insertion.
