LED

Introduction

A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. A diagnostic LED on a digital signage player provides a visual indication of the device's status and helps in troubleshooting. It uses different colors or blinking patterns to signal whether the player is operating normally, in standby mode, or experiencing issues. This makes it easier to quickly identify and address any problems.

Depending on the player model, one or more diagnostic LEDs can be found, as follows:

• The iBX players have two LEDs on the front side indicating power and SSD activity.
• The HMP400 and HMP400W players have four diagnostic LEDs on the front side indicating power, system, Wi-Fi and network.
• The HMP350,HMP300, and DiVA models have two diagnostic LEDs (power and system).
• The HMP200 model has three diagnostic LEDs (power, system, and network),
• The HMP130 and HMP100 models have a single diagnostic LED.

Additionally, the Ethernet connector on some players have built-in LEDs to indicate the link status and activity of the network connection, as explained below.

iBX players

All the iBX players have the following LEDs on the front side:

• Power LED ⇒ light up solid red when the player is powered and running.
• SSD LED ⇒ blinks green when the internal storage is accessed.

The Ethernet connector on iBX410 and iBX410W players also feature two LEDs:

• Left LED shows the network speed by changing its color, as following:

  off ⇒ 10/100 Mbps network

  solid green ⇒ 1000 Mbps (Gigabit) network

• Right LED shows the network activity, as following:

  off ⇒ the link is not present

  solid amber ⇒ the link is present;

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

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

SYS LED

The SYS (system) LED is:

• blinking green when the player is running normally (after the boot has completed)
• solid green (without blinking) - 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
• blinking red four times per second when the player is in Recovery mode
• off, when the device is shut down

Network LEDs

Ethernet port LEDs

The two LEDs present on the Ethernet port connector have the following meaning:

• Left LED shows the network speed by changing its color, as following:
  • solid green for 1000 Mbps (Gigabit) network;
  • solid orange for 100 Mbps network;
  • off for 10 Mbps network.
• Right LED has a yellow color and shows the network activity, as following:
  • solid color when the link is present;
  • blinks when there is link activity (i.e. network packets);
  • off when the link is not present.

HMP200

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 HMP can be safely unplugged), yet the HMP is under external power (pressing the blue button turns on the HMP);
• blinking red at 2 Hz (i.e. twice every second) when the internal temperature is over the limit and the HMP has automatically powered itself off (with automatic wake up) to cool down.

SYS LED

The SYS (system) LED is:

• blinking green once per second when the HMP is running normally (after the boot has completed);
• blinking red four times per second when the HMP is in Recovery mode.
• off, when the device is shut down.

Network LED

The network LED (after startup) is:

• green with occasional or no blinking when the Ethernet link and a valid IP address are present (the blink represents network traffic);
• green with regular orange blinking when the Ethernet link is present, but the IP address is auto-configured in the range 169.254.1.0-169.254.254.255 (indicates DHCP server problem);
• solid orange when no IP address is assigned (this should only happen momentarily between addresses changes);
• blinking red once per second (in sync with SYS LED) when there's no Ethernet link detected and the IP address is auto-configured in the range 169.254.1.0-169.254.254.255;
• off, when there's no Ethernet link detected (yet a valid IP address is present).

HMP130, HMP100

The diagnostic LED is:

• blinking green once per second when the HMP is running normally;
• blinking green four times per second when the HMP is in Recovery mode;
• blinking orange when there's an IP address conflict or no DHCP server is found (the HMP is using an auto-configured IP in the range 169.254.1.0-169.254.254.255);
• alternates between solid orange and solid red when the HMP doesn't have an IP address (should only be temporary);
• solid red (without blinking and while the network cable is unplugged) when there's a hardware problem with the HMP (this most probably will require an RMA);
• off, when the device is shut down.
