LED

Introduction

Depending on the model, one or more diagnostic LEDs are present on the players:

The HMP400 has four diagnostic LEDs on the front side indicating power, system, Wi-Fi and network. Two more are integrated within the network connector on the back side.
The HMP350,HMP300, and DiVA models have two diagnostic LEDs (power and system), plus two integrated within the network connector,
The HMP200 model has three diagnostic LEDs (power, system, and network),
The HMP130 and HMP100 models have a single diagnostic LED.

These LEDs can be used to quickly assert the status of the device according to the color and blinking frequency, as is detailed below.

HMP400, HMP400W

Power LED

The power LED is marked with two lines, one continue and one discontinue, and can have the following states:

solid red or blinks blue ⇒ there's a problem with the power; if using the external USB-C power supply, try using to PoE instead; if that doesn't fix it, then it's an RMA.

solid blue ⇒ the system is powered off (i.e. the shutdown is completed and the player can be safely unplugged), yet the player is under external power (pressing the blue button turns on the player)

solid green ⇒ power is OK and the internal components are powered up

System LED

The system LED is marked with a heart-beat like line and can have the following states:

off ⇒ the device is shut down

blinks red (four times per second) ⇒ the player is in Recovery mode

blinks green ⇒ the player is running normally (after the boot has completed)

solid green ⇒ this should not happen, unless the player is stuck during boot phase; unplug the power for 2 minutes, use another power supply, or force Recovery mode with the blue button; if none fixes it, then it's an RMA

Network LEDs

On the front side, there are two network LEDs: one for Wi-Fi and one for wired network. On the back side, there are two more LEDs integrated within the network connector.

Wireless network LED

The wireless network LED can have the following states:

off ⇒ no wireless support (i.e., HMP400, or HMP400W but the wireless module is faulty or absent)

blinks yellow ⇒ the player is not fully configured and it accepts a Wi-Fi configuration (e.g., via USB)

solid yellow ⇒ the player is fully configured and the Wi-Fi is disabled (i.e., it is configured for Ethernet)

blinks red ⇒ the player is configured for Wi-Fi, but it is not connected to Wi-Fi because of one of the following: it is still booting, none of the configured networks was found, or network authentication failed

blinks alternatively red and green ⇒ the player is configured for Wi-Fi and connected to Wi-Fi but no routable IPv4 address is set (i.e., DHCP failure or static IPv4 address conflict)

solid green ⇒ the player is configured for Wi-Fi and fully connected

Wired network LED

The front-side wired network LED can have the following states:

off ⇒ when the link is not present

solid amber ⇒ there's a 10/100 Mbps network link detected;

solid green ⇒ there's a 1000 Mbps (Gigabit) network link detected;

Ethernet port LEDs

On the back side, there are two LEDs integrated within the network connector.

Left LED shows the network speed:
off ⇒ 10/100 Mbps network

solid green ⇒ 1000 Mbps (Gigabit) network
Right LED shows the network activity:
off ⇒ the link is not present

solid amber ⇒ the link is present;

blinks amber ⇒ there is link activity (i.e., network packets);

HMP350, HMP300, DiVA

PWR LED

The PWR (power) LED is:

solid green (without blinking) when power is OK and the internal components are powered up
solid red (without blinking) when the input voltage level is out of bounds
blinking red briefly once every two seconds (i.e. on for 250 ms and off for 1750 ms) when the system is powered off (i.e. the shutdown is completed and the player can be safely unplugged), yet the player is under external power (pressing the blue button turns on the player)
blinking red at 2 Hz (i.e. twice every second) when the internal temperature is over the limit and the player has automatically powered itself off (with automatic wake up) to cool down
