HP 5120 EI, 5120 SI manual RPS status LED description, Ethernet port LED description 5120-48G SI

LED mark	Status	Description
	Flashing green (1 Hz)	The system is performing power-on self test (POST) or
		downloading software.
	Flashing green (3 Hz)	POST has failed or another fatal error has been detected.
	Off	The switch has been powered off.

RPS status LED

The 5120-24G-PoE+ SI switch has one RPS status LED on its front panel to show the operating status of the RPS DC input.

Table 30 RPS status LED description

LED mark	Status	Description
RPS	Steady green	The RPS DC input is normal.
	Off	The RPS unit is not connected or the RPS DC input is abnormal.

Port mode LED

The 5120-8G-PPoE+ SI, 5120-8G-PoE+ SI, 5120-24G-PPoE+ SI and 5120-24G-PoE+ SI switches have a port mode LED to indicate the type of information that the network port LEDs (excluding the SFP port LEDs) are showing. You can use the port LED mode switching button to change the type of displayed port information.

Table 31 Port mode LED description

LED mark	Status	Description
	Steady green	The network port LEDs are showing port rates.
Mode
	Flashing green (1 Hz)	The network port LEDs are showing the status of PoE power
		supply on the ports.

10/100/1000Base-T Ethernet port LED

The 5120-48G SI switch has one bi-color LED (see Table 32) for each 10/100/1000Base-T Ethernet port, and all other 5120 SI switches have two LEDs (see Table 33) for each 10/100/1000Base-T Ethernet port. The 5120-8G-PPoE+ SI, 5120-24G-PoE+ SI, 5120-24G-PPoE+ SI, and 5120-24G-PoE+ SI switches also use a port mode LED to indicate the type of information that the port LEDs are displaying (see Table 34).
