DC Power Supply Unit (PSU)

Smart-1 6000-L/6000-XL Security Management Appliances support up to two DC redundant power supply units (PSUs).

* DC current consumption: 32 A (maximum).

Notes:

  • The appliances support PSU redundancy. One PSU is sufficient for the normal appliance operation.

  • Installing DC PSU and AC PSU together is not supported and triggers a mismatch event - the DC PSU indicator LED flashes green.

  • When only one PSU is installed, it must be installed in the first PSU bay - see the markings on the appliance cover.

  • To ensure proper appliance cooling, leave the failed PSU in place until you get the replacement PSU. This prevents the cooling air from escaping.

  • When two PSUs are installed, and the appliance is powered on, you must remove and replace only one PSU at a time.

  • When two PSUs are installed, they must be of same type and have the same maximum output power.

  • When two PSUs are installed, they must receive the same input DC voltages.

  • When two identical PSUs are installed, power to the appliance is supplied equally from both PSUs to maximize efficiency.

Indicator LED

Indicator lights for DC PSU

Each DC PSU has a LED that illuminates with different colors. This LED shows whether DC power is received, or a PSU fault occurred.

LED light

Description

Steady green

A valid DC power source is connected to the DC PSU.

The DC PSU is operational.

Flashing green

When you hot-plug a DC PSU, the DC PSU indicator LED flashes green. This indicates that there is a mismatch between this hot-plugged DC PSU and the other installed DC PSU. The mismatch is in any of these PSU characteristics: efficiency, feature set, health status, or supported voltage.

Make sure that both DC PSUs are the same.

Notes:

  • When correcting a PSU mismatch, replace only the DC PSU with the flashing indicator. Swapping the other DC PSU to make a matched pair can result in an error condition and unexpected appliance shutdown.

  • Installing DC PSU and AC PSU together is not supported and triggers a mismatch event.

Flashing amber

Indicates a problem with the DC PSU.

Off

DC power is not connected to the DC PSU.
