Controller Ethernet Connection (if required)
The controller provides a Web Interface via an Ethernet connection to a TCP/IP network. This interface can be
accessed locally on a computer or remotely through a network. An RJ-45 10BaseT jack is provided on the front
of the controller for connection into a customer's network. This jack has a standard Ethernet pin configuration
scheme, twisted pair. Refer to
for location and
for pin outs. Use shielded Ethernet cable
(grounded at both ends). Note that the RJ-45 jack is connected to chassis ground. Refer to the NCU
Instructions (UM1M830BNA) for operational details.
NOTE!
You can access the Web pages of the power system locally by using a "crossover" or “straight”
cable connected directly between your PC and the NCU Controller.
WARNING!
The intra-building port(s) of the equipment or subassembly is suitable for connection to
intra-building or unexposed wiring or cabling only. The intra-building port(s) of the equipment or
subassembly MUST NOT be metallically connected to the interfaces that connect to the OSP or its
wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4 ports as
described in GR-1089-CORE, Issue 4) and require isolation from the exposed OSP cabling. The addition
of Primary Protectors is not sufficient protection in order to connect these interfaces metallically to OSP
wiring.
The intra-building port (RJ-45) of the equipment or subassembly must use shielded intra-building
cabling/wiring that is grounded at both ends.
