Connecting Power Cords
WARNING! The storage system power cords are used as main disconnect devices. To
ensure that the power cords can be disconnected quickly, locate the storage system near
an easily accessible power outlet.
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.
NOTE! A fully loaded storage system can run on one power module. If the storage system has
two power modules for redundancy, we recommend that you plug the power cord for each power
module into a separate uninterruptable power supply (UPS). This will allow the storage system to
continue operating if one of the ac power sources fails.
To connect power cords:
Connect power cords to the P1 and P2 ac power connectors on the rear of the storage system (see Figure
10). In a redundant power module configuration, if one power module fails, the other power module will
provide power for the entire storage system.
