EMC Rails and Enclosures (CX3-10 Class and CX3-20 Class Storage Systems) Field Installation Guide
Setting up an installed storage system
Connecting AC
power
CAUTION
The storage system and DAEs will power up immediately once you
attach them to an active AC power source. Before connecting to a
power distribution unit or standby power supply:
◆ plan your power configuration.
◆ Set the SPS switches to the off (0) position.
◆ Unless your cabinet is in active use with another system, set the
master (or main circuit breaker) switches to the off position.
1. Plug an AC line cord into each DAE3P-OS power/cooling
module, as shown in Figure 20. Connect only the DAE3P-OS (the
first disk enclosure in the storage system, with the specially
marked "array software" disks) at this time.
Make certain you secure the power cord with the retention bails (strain
reliefs) at each connector. The strain reliefs prevent the power cord from
pulling out of the connections.
