AC power cords.
The controller-drive tray and the drive trays
ship with power cords for connecting to an
external power source, such as a wall plug.
Your cabinet might have special power
cords that you use instead of the power
cords that ship with the controller-drive
tray and the drive trays.
(Optional) Two DC power connector cables
are provided with each drive tray for
connection to centralized DC power plant
equipment.
– Four DC power connector cables are
provided if additional redundancy is
required.
– A qualified service person is required
to make the DC power connection per
NEC and CEC guidelines. A two-pole
20-amp circuit breaker is required
between the DC power source and the
drive tray for over-current and short-
circuit protection. Before turning off
any power switches on a DC-powered
drive tray, first you must disconnect
the two-pole 20-amp circuit breaker.
Copper SAS cables - Use for all drive-side
connections within the storage array.
Fiber-optic cables - Use for FC connections
to the drive trays.
For the differences between the fiber-optic
cables and the copper Fibre Channel (FC)
cables, see Section 2.2.3 Things to Know –
SFP Transceivers, Fiber-Optic Cables, Copper
Cables, and SAS Cables, page 17
