1. Introduction

The Metrici Server is a compact mini-PC platform that we deliver to customers with one or more Metrici detection engines pre-installed and ready to go. It is built around a small-form-factor industrial board enclosed in a custom Metrici chassis.

The unit ships as a pre-configured appliance with the operating system and Metrici engines already installed, no software setup is required on site. However, the engines must be customized by the user for the specific deployment: adding cameras to the engines, configuring detection parameters, and completing the setup in the Metrici Web Interface.

Once powered on and connected to the network, the unit is ready for this configuration to be performed for both Metrici Engines and Metrici Web interface.

2. Hardware Overview

The Metrici Server has a clear front/back split. All everyday user-facing controls and ports — including the power button — sit on the front panel. All persistent connections — power, network, and displays — sit on the back panel.

Back Panel

The back panel hosts the connectors that stay plugged in during normal operation:

DC Input Jack — 12–20 V DC barrel connector for the power adapter. The jack accepts a 5.5 mm OD / 2.5 mm ID plug.
HDMI 2.1 Port 1 & Port 2 — two HDMI outputs with built-in CEC support. Both can drive 4K displays.
RJ-45 LAN — 2.5 Gigabit Ethernet. The connector has two integrated LEDs: a green link/activity LED on the left, and a green/yellow data-rate LED on the right.
USB 3.2 Gen 2 Type-A — one USB-A port (blue).
USB 2.0 Type-A — one USB-A port (black).
Thunderbolt™ Type-C — two Thunderbolt 4 / USB4 ports (where fitted). USB4-compliant with up to 15 W (5 V / 3 A) port bus power.

LAN Connector LED Reference

Link (green)	Blinking	LAN activity in progress
Data Rate	Off	10/100 Mb/s
Data Rate	Yellow	1000 Mb/s
Data Rate	Green	2500 Mb/s

3. Power

The Metrici Server ships with a 120 W, 19 V DC power adapter. Use only the supplied adapter or an equivalent unit that meets the specifications below — using an underpowered adapter can cause unexpected shutdowns under load.

Power Specifications

Adapter: 120 W, 19 V DC (shipped in the box)
Accepted input range: 12–20 V DC ±5%
Maximum current draw: 10 A peak at the DC input jack
Connector: 5.5 mm OD / 2.5 mm ID barrel plug, centre-positive

Important! The unit also has an internal 12–20 V DC power header on the board (used in custom integrations). Never connect the external DC jack and the internal power header at the same time. There is no isolation circuitry between them, and doing so can damage the board, the adapter, or both.

Power Button

The power button is on the front panel. It has the following behaviours:

Short press (when off): powers the unit on. Normal POST and OS boot follow.
Short press (when on): initiates a graceful operating-system shutdown.
Hold for 3 seconds (when off): opens the BIOS Power Button Menu (advanced — see your service contact).
Hold for 4+ seconds (when on): forces an immediate hard power-off. Use only if the system is unresponsive.

The button's integrated LED reflects the system state — off when powered down, blinking during standby, and steady during normal operation.

4. First Boot

The Metrici Server arrives ready to use. To bring it online for the first time:

Place the unit on a flat surface (see Chapter 6). Leave at least a few centimetres of clearance around the vents to ensure proper airflow.
Connect the network cable to the back-panel RJ-45 port.
Connect a display to one of the HDMI ports. The unit can run headless — see Chapter 5.
Connect the supplied 19 V DC power adapter to the back-panel DC jack and to mains power.
Press the front-panel power button briefly.

Within roughly 30–60 seconds the operating system completes boot and the Metrici engines start automatically as background services. The IP address assigned to the unit was either configured by Metrici before shipping (and is documented in the delivery note) or is obtained by DHCP from your network.

Note: The unit can be configured to power on automatically when AC power is restored after an outage. This is a BIOS setting and is typically enabled by default on units delivered for unattended deployments. Contact Metrici support if you need to change this behaviour.

5. Display Emulation

The Metrici Server is often deployed without a monitor permanently attached. By default, integrated graphics on most platforms refuse to allocate a framebuffer when no display is connected, which prevents remote desktop tools, screen recording, and certain detection engine pipelines from running correctly.

To avoid this, the Metrici Server supports display emulation on its HDMI ports. Display emulation lets the system behave as though one or two displays are always connected, even when nothing is physically plugged in. Two modes are available, both configurable in BIOS:

Virtual Display Emulation

Provides a virtual 1280 × 1024 display when no real display is connected. If one real display is connected, the emulated display is provided as a second output. If two real displays are connected to the HDMI ports, both real displays are used and no emulation is provided.

Persistent Display Emulation

Behaves as if both HDMI displays are always connected, regardless of whether they are physically present. The EDID information from each display remains programmed across S3, S4, S5, and G3 power states until the feature is disabled. This is the recommended setting for headless Metrici deployments.

When persistent display emulation is enabled, an additional BIOS option called Inconsistent Display Device becomes available. It controls how the system reacts when a newly connected display reports EDID parameters different from the ones currently programmed:

Block boot (default): the BIOS shows a warning and waits indefinitely for the user to make a selection.
Countdown: the BIOS shows a warning and proceeds with boot after 10 seconds.

Note: When persistent display emulation is enabled, the system will continue to drive the originally connected display's EDID even if you swap monitors. To retrain the system for a different display, disable persistent display emulation in BIOS, reboot, then re-enable it with the new display attached.

For Metrici-delivered units, display emulation is typically pre-configured to match the deployment scenario. If you need to change it, contact Metrici support before adjusting BIOS settings.

6. Placement

Place the server on a clean, flat, stable surface in a well-ventilated area, away from direct sunlight, heat sources, and high-dust environments. The mounting location should support the full weight of the unit and any attached cabling without flexing. Avoid placing the unit near radiators, vents, photocopiers, or other equipment that produces heat, vibration, or particulate matter, and do not install it on carpeted floors or in enclosed cabinets without active ventilation.

Important! Do not block the chassis vents. Leave clearance around the unit for airflow. Operating the server with restricted airflow will cause the processor to thermally throttle, reducing performance, and may shorten product lifetime.

7. Environmental

The Metrici Server is qualified for 24/7 sustained operation. The board has a demonstrated Mean Time Between Failures (MTBF) greater than 50,000 hours.

Parameter	Specification
Operating Temperature (ambient)	0 °C to +40 °C
Storage Temperature (sustained)	−20 °C to +40 °C
Storage Temperature (short, e.g. shipping)	−40 °C to +60 °C
Humidity	Non-condensing during operation and storage

Note: Processor performance may automatically decrease when ambient temperature is in the top 5 °C of the supported range. For best sustained throughput, deploy the unit in a climate-controlled environment.

8. Troubleshooting

Unit does not power on

Verify the power adapter is firmly seated in the back-panel DC jack and connected to a working mains outlet.
Check that the cable locking arm is not pinching the adapter cable.
Confirm the supplied 19 V / 120 W adapter is being used — third-party adapters with insufficient wattage may cause boot failures.
Try briefly disconnecting AC power for 30 seconds, then reconnect and press the power button.

Unit powers on but no video on the connected monitor

Try the other HDMI port — both are active by default.
Test the HDMI cable on a known-good display.
If the unit boots and the network is reachable but no video appears, the display you are using may have an EDID conflict with persistent display emulation. See Chapter 5.

No network link

Check the LAN connector LEDs. If the link LED is off, the cable, switch port, or patch may be the issue.
Verify the network cable is firmly seated on both ends.
If the unit was pre-configured with a static IP, make sure your network matches that subnet.

Metrici engines do not start after boot

Allow up to 60 seconds after the OS finishes booting — the engines start as background services and may take a moment to initialize.
Contact Metrici support with the unit serial number for further diagnostics.

System suddenly shuts down under load

This is almost always a thermal event. Check the CPU temperature in the BIOS/UEFI or system monitoring tools for signs of thermal throttling or over-temperature shutdown events logged before the failure.
Check that the chassis vents are unobstructed and that ambient temperature is within the supported range (Chapter 7).
