Monitoring the NK-RP1 Series

Both the NK-RP1/P and NK-RP1/PN have an LED on the front panel to indicate if the unit is operating normally.
There are also up to four LEDs inside to indicate if the power supplies are functional. Two of these LEDs are
located on the NK-RP1-NEG power modules and indicate if they are providing -15V to the system.

Monitoring via the Front Panel LED

The front panel LED on the NK-RP1/P and NK-RP1/PN indicates when the unit is operating normally. If the LED
is not illuminated, one or both of the +15V power supplies are not operating.

Table 4.1 Front Panel LED

LED Status Description

Front Panel On When the LED is lit, both of the +15V power supplies are active

and providing redundant power to the connected devices.

Off When the LED is not lit, one or both of the +15V power supplies

are not operating.

For More Information on...

• the location of the front panel LED, refer to the section “Front Panel Overview” on page 2–11.

Monitoring the Power Supply LEDs

Two LEDs behind the power supply retaining bar indicate the status of each +15V power supply.
