Step 4. Connect the power cords WARNING To avoid electrical fire hazard, use a branch circuit breaker properly rated for each power supply. If multiple enclosures are connected to a single branch circuit, multiply the number of enclosures times the maximum current, then select a circuit breaker with at least a 20% higher current rating. See Table 2. To optimize system availability, each power supply should be connected to a separate power bus. All wiring should meet or exceed local electrical wiring codes. The product power cords are used as main disconnect devices. To ensure that the power cords can be disconnected quickly, locate the product near an easily accessible power outlet.

Step 4. Connect the power cords
WARNING
To avoid electrical fire hazard, use a branch circuit breaker
properly rated for each power supply. If multiple enclosures are
connected to a single branch circuit, multiply the number of
enclosures times the maximum current, then select a circuit
breaker with at least a 20% higher current rating. See
Table 2
.
To optimize system availability, each power supply should be
connected to a separate power bus. All wiring should meet or
exceed local electrical wiring codes.
The product power cords are used as main disconnect devices.
To ensure that the power cords can be disconnected quickly,
locate the product near an easily accessible power outlet.

Enclosure Electrical Specifications
1
Connect the male ends of the power cords to one of the following ac power
outlets:
—
Separate ac circuits.
—
Separate uninterruptible power supplies (UPSs).
—
For racked enclosures, separate power distribution units (PDUs).
2
Connect the female ends of the power cords to the ac power connectors on
controller enclosures and disk enclosures. See
Figure 9
.
Note
Make sure that the locations of power cables do not interfere
with the removal of field replaceable units.
