Connecting the Power Cords
The E2600 controller-drive tray and the DE1600 drive tray can have either standard power
connections to an AC power source or the optional connections to a DC power source (–48
VDC).
NOTICE!
Make sure that you do not turn on the power to the controller-drive tray or the connected
drive trays until this documentation instructs you to do so. For the correct procedure for
turning on the power, see Section 11 Turning on the Power and Checking for Problems, page 64.

For each AC power connector on the drive tray, make sure that you use a separate power
source in the cabinet. Connecting to independent power sources maintains power
redundancy.
To ensure proper cooling, do not operate a drive tray with one of its power supplies
removed.
You can use the power cords shipped with the controller-drive tray with typical outlets
used in the destination country, such as a wall receptacle or an uninterruptible power
supply (UPS). These power cords, however, are not intended for use in most EIA-
compliant cabinets.

DC power connector
Each power-fan canister has two DC power connectors. Be sure to use a separate power
source for each power-fan canister in the drive tray to maintain power redundancy. You
may, optionally, connect each DC power connector on the same power-fan canister to a
different source for additional redundancy.
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.
