The JNP-PWR-3K-AC PSM supports AC, high-voltage AC (HVAC), or high-voltage DC (HVDC) input.

The PSM automatically detects whether there is AC, HVAC, or HVDC input and manages the power accordingly. The PSM provides 3000-watt (W) DC output.

Each PSM has its own fan and is cooled by its own internal cooling system. Hot air exhausts from the rear of the chassis.

Each PSM has two independent 16-Amperes (A) rated AC/HVAC/HVDC inlets on the faceplate. Though each inlet provides sufficient input power to provide full output, always connect both inlets to dedicated AC/HVAC/HVDC power sources to provide redundancy.

Each JNP-PWR-3K-AC PSM has a power switch with international markings for on (|) and off (O), a fan, and four status LEDs on the faceplate.

Table 2 shows the physical specifications of the AC/HVAC/HVDC PSM.

The JNP-PWR-3K-AC PSM has four LEDs on its faceplate: 0 (INP0), 1 (INP1), OK (Power OK), and ! (Fault). These LEDs display information about the status of the PSM.

Table 4: LEDs on the JNP-PWR-3K-AC PSM

LED	Color	State	Description
0 (INP0) and 1 (INP1)	Green	Solid	The input power is within normal operating range.
	Amber	Blinking	The input power is not within normal operating range.
	None	Unlit	The PSM is switched off; the voltage is zero.
OK (Power OK)	Green	Solid	The output power is within normal operating range.
	Amber	Blinking	The output power is not within normal operating range.
! (Fault)	Red	Solid	The PSM has failed; you must replace it.
	None	Unlit	The PSM is functioning normally.

You can get additional information about the status of the PSMs by using the show chassis power command.

The JNP-PWR-3K-DC PSM can operate with an input current of either 60 A or 80 A. The PSM has two independent pairs of DC input lugs (labeled Input 0, RTN, –48V/–60V and Input 1, RTN, –48V/–60V) on the faceplate of the PSM. Each inlet requires a dedicated DC power feed. You must always connect each of inlet the PSM to a dedicated DC power feed to provide redundancy. Only one power feed is operational at a time. You can configure the input using a dual inline package (DIP) switch on the PSM faceplate.

Each PSM has its own fan and is cooled by its own internal cooling system. Hot air exhausts from the rear of the chassis.

The PSM has a power switch with international markings for on (|) and off (O), a built-in fan, and four status LEDs on the faceplate.
