Reset Button

Pressing the Reset Button

The power supply module has a Reset button on its front panel.

DANGER

HAZARD OF ELECTRIC SHOCK

Do not touch the Reset button directly.
Use an insulated tool to press the Reset button.

Failure to follow these instructions will result in death or serious injury.

NOTE: The power is still present on the backplane when pressing Reset button.

Standalone Configuration

Pressing the Reset button of a standalone power supply module, triggers an initialization sequence of the modules on the rack that it supplies.

As a consequence:

The ALARM relay is forced to open state, and
The power supply OK LED is switched off.

Redundant Configuration

In a redundant configuration, pressing one of the Reset buttons of the power supply modules, triggers an initialization sequence of the modules on the rack that they supply. There is no need to press simultaneously both Reset buttons of the redundant power supply modules.

As a consequence:

Both ALARM relays are forced to open state, and
The OK, RD, and ACTIVE LEDs of both power supplies are switched off.
