Each 12-drive or 24-drive tray in a storage array must have a minimum of two drives for proper operation, while each 60 drive tray must have a minimum of 20 drives with four drives across the front row of each drawer for proper operation.
All 60-drive trays have a limit of five solid state drives (SSDs) per drawer. If you exceed this limit for SSDs in a particular drawer, the power source in the drawer is likely to receive too much current and could fail.
This section provides an overview of hardware described in this document. For specific details about how LEDs operate, see Step 10 - Turning on the power and checking for problems in a controller-drive tray.

You can order an optional DC power supply connection and connector cables for the drive tray. A qualified service person is required to make the DC power connection per NEC and CEC guidelines . A two-pole 30-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, you must disconnect the two-pole 30-amp circuit breaker.
