3.18 Cable and Power Cord Routing and Connections
3.18 Cable and Power Cord Routing and Connections
The internal Storage element power cords have been factory-installed and
routed. SDI/DSSI cables are factory installed for the mounted storage elements
only. The SDI/DSSI cables have been connected to the cabinet I/O bulkhead
panel. The power cords have been connected to the rear panel of the power
controller.
Go to the rear of the cabinet. The storage element connections for both internal
SDI/DSSI cables and power cords are coiled and tie-wrapped at the factory.
Carefully cut the cable tie, then connect the SDI/DSSI cable connectors to the
proper port connections on the rear of the storage element.
The 110/120 Vac version of the cabinet are preconfigured with power cords for
all six possible positions.
3.19 Applying Power
This chapter describes the Sx300 storage element switches and power
controller power connector configurations encountered when installing a disk
or tape drive in an DECArray300 cabinet system. Brief descriptions of the
power controller switches, the storage element voltage selector switch, and the
circuit breaker are included.
This chapter does not discuss fault codes or error conditions incurred at
power-up. Please refer to the specific storage element manuals for such
information.
3.20 Power Controller
The power controller has six switched and two unswitched outlets (a total of
eight outlets). All variations include an ac line filter. The power controller is
19-inch rack-mountable.
The power controller serves four functions:
Controls large amounts of power from a remote source
Provides a convenient ac power distribution point for multiple units
Protects equipment from some electrical disturbances
Disconnects power (in case of overload) and provides circuit breaker
protection
