2 ONEREACH SYSTEM INSTALLATION
2
2.1 Overview
The system consists of three parts: Power Injection (PI), the OneReach Cable Assembly (OCA),
and the Remote PoE Port (Remote). The variety of available components allows you to build a
custom system for your exact needs – each is designed to work together for ease of use and a
streamlined installation.
If any of the OneReach components or devices supported by OneReach are or will be
located outdoors or subject to electrical surges, see Sections 3.5, 3.6, and 3.7 for important
grounding and surge suppression information.
2.1.1 Power Injection
Power Injection starts from the Power Injection Chassis or the PI Source on single channel
systems (described later). The rack mountable chassis, located in a local closet, accommodates
the slide-in 4-port Media Modules and injects the power and the data from active networking
equipment into a hybrid fiber optic and copper cable. The power supply is compliant with the
requirements for Class 2 per NFPA 70-2017 when used as part of the OneReach system.
The 4U chassis with rear terminal blocks has a capacity of 12 single-sized slots and accepts
one to three power supplies plus up to six media modules. Each slide-in Media Module supports
four Ethernet ports.
The 2U chassis accepts the same power supplies and media modules, but with a capacity of six
single-sized slots.
Slide-in Power Supply Modules (PSM) provide 400W of power from each AC input and are
equipped with active ventilation. At least one PSM is required, with a second or third PSM
specified when required for additional power. Each PSM will support twelve PoE, eight PoE+
or four HPoE devices. The maximum number of PSMs in any one chassis shall be three. The
screw terminals cannot be used to wire chassis together, nor should other means be used in an
attempt to transfer power between chassis.
