Figure 2-3. Remote Unit Outdoor Cabinet

3.1 Primary Components

The RU outdoor cabinet consists of the enclosure, mounting slots for the STM and LPA modules,

connectors and a wiring harness for interfacing the STM and LPA modules, a mounting slot for

either the WDM or CWDM module (accessory items), lightning protector, and two fiber storage

spools. The RU outdoor cabinet is designed for use in an outdoor environment. Opening the

hinged door provides full height and width access to the interior of the enclosure to facilitate

module and cable installation.

The enclosure is constructed of heavy gauge aluminum and is painted putty white for corrosion

protection. Connection and/or entry points are provided in the bottom of the enclosure for the

antenna coaxial cable, fiber optic cable, and AC power cable. Vent openings are provided in the

bottom of the enclosure to permit air exchange for cooling. The RU cabinet is weather-tight but

contact with salt-air mist should be avoided as it may degrade the Mean Time Between Failure

(MTBF) of the product. Drain holes in the bottom of the cabinet allow any moisture that does

enter the cabinet to drain out. The cabinet door is equipped with a sturdy latch so that the

enclosure may be padlocked to prevent unauthorized entry. A door open switch is provided so

that a major alarm is generated whenever the cabinet door is opened.

NOTE: EACH DIMENSION INCLUDES AN

ALLOWANCE FOR ANY COMPONENT THAT

PROJECTS OUTWARD FROM THE CABINET

SUCH AS THE DOOR LATCH.
