This topic describes the controls, connectors and indicators.

For more information about the connectors and cabling requirements, see .edge - Wiring.

Controls Overview

All controls, connectors and indicators are located on the front and rear panel, with the exception of the grounding screw (10).

Power Supplies

The .edge frame can be ordered with either AC or DC power supplies. Only one PSU is required for operation; the second provides redundancy.

Before connecting power to the device, please read and observe all of the important safety information in .edge - Power Supplies.

For more information about what happens once power is applied, see .edge - Powering On.

Front Grill / Fans

.edge is cooled by five temperature-controlled fans (fitted behind the front grill).

Air is taken in from the front and blown out, across the processing blades, to the right side.
The fan activity is controlled automatically by the master processing blade.

The health of the fans can be interrogated using the Health pages (in HOME's Advanced parameters).

Network Interfaces

Each processing blade is equipped with 8 network interfaces: 6 media + 2 management ports.

The six media ports handle the IP streaming to the media network(s): 4 x 25GbE (via SFP28) and 2 x 100GbE (via QSFP28).
The two MGMT ports handle the administration and control: 2 x 1GbE (via SFP).

Media Ports

The active media ports are determined by the operating mode of the processing blade: 25G (only), 100G (only) or 100G+proxy (all six ports are active: the 100G ports handle the original signals; the 25G ports handle the proxy flows).

25G comes as standard; 100G requires an optional license.
25Gbps is fine for SD and HD; 100Gbps is required for 3G and UHD.

Please note: a 100G license is required to support the 100G and 100G+proxy modes. If a 100G license is not available, then the blade runs in 25G (only) mode and the 100G ports are inactive.

For each stream, you can decide whether it will be transmitted or received via the primary or secondary port. To achieve redundant streaming, you must use both interfaces. The image below shows the location of the primary and secondary interfaces.

The connections are made as follows:

SFP 1 to 4 - 4 x 25GbE (via SFP28). Active if the operating mode = 25G or 100G+proxy:
QSFP 1 & 2 - 2 x 100GbE (via QSFP28). Active if the operating mode = 100G or 100G+proxy.

MGMT Ports

The two management ports handle the administration and control. They can be addressed in one of two ways, depending on which is more convenient:

Out-of-band - control data arrives via the MGMT ports: 2 x 1GbE (via SFP). This scheme requires a dedicated management network. To achieve redundant control, you must use both interfaces.
In-band - control data arrives via the media ports. This scheme can be used if there is no separate management network.

Using the Network Interfaces

To use the network ports, you must fit the correct optical transceivers. These must be Lawo-certified (as described here). The optical transceiver determines the cable type, maximum distance and connector.

Each network port has a Link Status LED that can be used to check the Ethernet connection.

Link Status LED	Meaning	Recommended Actions
Green	Link up (ok).	No action required.
Yellow	Link down: optical transceiver detected but no connection.	Check the connection to the network switch.
Off	Link down: optical transceiver missing.	Check the fitting of the optical transceiver.

The link status and IP settings can also be interrogated using HOME's Network Ports tab.

Call Home & ID

The Call Home (button) and ID (LED) can be used to identify the hardware in the HOME Web UI. This can be extremely useful when you are configuring more than one blade.

The ID LED has three possible states:

Green (fully lit) = Identify Hardware inactive (normal state).
Red to Blue, alternating = Identity Hardware active.
Off = processing blade is off (no power).

To identify a processing blade, either press and hold Call Home (on the unit) for at least 2 seconds or select Identify Hardware (in HOME's General tab).

When Call Home or Identify Hardware is active, a “Says Hi” message appears in the HOME Web UI (as shown here).

To cancel the "Identify Hardware" mode, either deselect Identify Hardware (on the GUI) or press and hold the Call Home button again (on the unit).

The Call Home button can also be used to reset the network settings for the MGMT ports. This is described later in .edge - Network Settings.

Reset

The Reset button can be used to reset the power of the processing blade. The button is recessed to prevent accidental operation. After the reboot, the blade loads the latest configuration.

You can also reboot a processing blade remotely using the Reboot option (from HOME's "Devices" list).

A processing blade can be reset to its factory default settings using the Factory page (in HOME's Advanced parameters).

USB-C

The USB-C (port) is provided for diagnostics.

In the event of a problem, you may be asked to connect this port to a service computer by a Lawo support engineer. The connection should be made using a standard USB Type-C cable.

Card Status LED

The Card Status LED shows the health of the processing blade and, on the master blade (fitted to the highest physical slot), the health of both the card (blade) and chassis (frame).

If the LED is green, then the processing blade (and chassis) are working properly.
If the LED is either amber or red, then there is either a warning or fault.

Typically, the chassis faults are either power or fan-related. In this instance, you may see a combination of LED states. e.g. If there is a power fault in the frame, then the top Card Status LED lights in red while all other Card Status LEDs are green.

The table below describes all possible meanings.

Card Status LED	Meaning	Recommended Actions
Green, intermittent	Ok	No action required.
Amber, intermittent	Warning	Check the Card Warning(s) on the System controls page (in HOME's Advanced parameters).
Red, blinking	Fault	Check the Card Fault(s) on the System controls page (in HOME's Advanced parameters).

Rear Panel

SDI Interfaces

Each rear I/O plate is equipped with 48 x HD-BNC for SDI interfacing.

The number of available SDIs is determined by the number of ".edge_sdi" licenses on the processing blade. In addition, the number of SDI inputs versus outputs can be changed using the Device Options (in HOME's General tab).

For all possible configurations, see .edge - Rear I/O Plates.

Reference Signal Interfaces

Each rear I/O plate is equipped with 5 x HD-BNC for external reference signals: 2 x REF IN, 2 x REF THRU and 1 x REF OUT.

The sync reference can be checked or changed using the Synchronization parameters (in HOME's Advanced parameters).

Functional Earth

A grounding screw (M5x12) is located on the right side of the frame (when viewed from the rear). This must be used to ground the frame.

See .edge - Grounding.
