Installation and Initial Setup

LA-5291 is a 1RU product intended to be permanently installed in standard 19 ½” equipment rack and secured with four standard rack screws. It is fan cooled with air intakes and exhausts located on the side of the unit just behind the front panel, but whenever possible, it is recommended to leave 1RU of empty space above and below the unit.
Plug the supplied IEC power cords into the LA-5291 and connect each to different mains power sources. Remember that while redundant supplies do protect against the unit losing power in the event of a PSU failure, the loss of mains supply voltage is a bigger concern. Accordingly, each supply should be fed from a different circuit equipped with adequate surge protection and fitted with an uninterruptible power supply (UPS).

The unit will power up as soon as the power cords are connected, and using the Reset button is not required on initial startup. The front panel of the unit will remain dark during most of the boot process but the Status LED will light. Once the boot process is complete, the Home Screen will appear and the Status LED will turn green.
LA-5291 ships with DHCP enabled and will automatically retrieve an IP address when connected to a network with a DHCP server.
Important - The Control and AES67 Ethernet connections both require 1000BASE-T (Gigabit) switch ports in order to work properly.
If both the Control and AES67 ports will be used, they must be in different subnets. In-band control is available using the AES67 port.
If only one port will be used, set the unused port to “Static IP” with an IP Address of 0.0.0.0, a Subnet Mask of 0.0.0.1, and a Gateway of 0.0.0.0.
To set a fixed IP address for the Control port:
Press the Right button once to show the Information screen and once more to navigate to the IP Configuration (Control) screen
Press the Down button to highlight “Edit”
Press the OK button to highlight “Use DHCP”
Press the Right button to highlight “Yes”
Press the Up/Down buttons to select “No”
Press the Left button to highlight “DHCP” again
Press the Down button to highlight “Address”
Press the Right button to move to the first digit of the IP address
Use the Up/Down buttons to change the value
Use the Right/Left buttons to select another digit to edit
When finished editing the Address field, press the Right/Left buttons to highlight “Address” again
Press the Down button to navigate to the “Netmask” field, following the instructions above for entering the value
When finished editing the Netmask field, press the Right/Left buttons to highlight “Netmask” again
Press the Down button to navigate to the “Gateway” field, following the instructions above for entering the value
When finished editing the Gateway field, press the Right/Left buttons to highlight “Gateway” again
Press the Down button to highlight “Update”
Verify the information has been entered correctly and press the OK button to save the new values
If you notice incorrect information and need to start over, use the Right button to highlight “Cancel” followed by the OK button
If you are using AES67 I/O, pressing the Right button from the IP Configuration (Control) screen will bring you to the IP Configuration (AES67) screen. The steps for configuring this port are identical to those above for the Control port.
Pressing the Right/Left buttons will eventually return you to the Home screen.
Our sincere hope is that you like your LA-5291 so much that you’ll eventually end up with dozens of them populating your racks, but since one LA-5291 looks pretty much like another, we’ve come up with a way to help you identify an individual unit.
When you enable the “Locate Mode” from the remote user interface, the unit’s front panel display will repeatedly change color until Locate Mode has been cleared by pressing any key on the front panel or by pressing the “Locate Unit” button on the remote user interface a second time. Enabling Locate Mode affects only the unit’s display and has no effect on the audio. Special Function Key Presses
To reset the unit to its factory defaults, simultaneously press and hold the Left, Up, and Right buttons for ten seconds until a red countdown timer appears in the bottom left corner of the display.
Important! Performing a factory reset will erase all I/O routing as well as any other custom settings you may have saved. This information cannot be reclaimed once you reset the LA-5291, even by contacting customer support or feeling genuine remorse for your decision. We strongly recommend backing up your configuration to a computer before performing a factory reset to avoid re-setter’s remorse. You have been warned!
LA-5291 includes a hard relay bypass that removes all internal circuits and processes from the signal path and connects each SDI and AES-3 input directly to its corresponding output.
To toggle the relay bypass on and off, simultaneously press and hold the Left, Down, and Right keys for three seconds until a red countdown timer appears in the bottom left corner of the display. Do not confuse this sequence with the Factory Reset procedure described above.
