Installation and Initial Setup
Using the Front Panel Interface
Physical Installation
The LA-5291 is a 1RU product intended to be permanently installed in a standard 19 1/2” equipment rack and
secured with four standard rack screws.
LA-5291 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.
Important:
Please see the “User Warnings and Cautions” section of this manual for important electrical safety information.
Power
The LA-5291 has two internal auto-ranging redundant power supplies protected by type T1AL25V fuses. Remem-
ber 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). Providing the receptacles
to which the supplied power cords are connected are grounded, the power connection serves as a ground.
Additionally, the rear panel earthing terminal should be connected to a proper ground system with 20 – 14 AWG
(0.5 – 1.5mm) wire.
Front Panel Buttons
As mentioned briefly in Chapter 2, the front panel of LA-5291 includes a five-button navigation cluster with Left,
Right, Up, and Down arrow buttons plus a green “OK” button in the center.
The arrow buttons are used for navigating through the menus, and the “OK” button acts as an “Enter” or “Select”
key.
