18 FX20/60 Supervisory Controllers Installation Instructions
Heartbeat LED
The yellow BEAT LED is located to the right of the
Ethernet status LEDs. Under normal operation, this
LED should blink about once per second. If the BEAT
LED stays on constantly, does not light, or blinks very
fast (more than once per second), contact your
technical support representative for assistance.
IMPORTANT: During boot-up, the heartbeat LED
blinks in a 90% on, 10% off pattern. Do not remove
power during this time, or data loss may result
(NDIO module’s firmware upgrade may be in
progress).
Status LED
The green Status LED is located to the right of the
heartbeat (BEAT) LED. This LED provides a central
processing unit (CPU) machine status check, and
remains lit whenever the FX20/FX60 is powered. If the
Status LED does not light while power is applied,
contact your technical support representative for
assistance.
Serial Port LEDs
LEDs for the 2 serial ports are located on the
FX20/FX60’s bottom board on the opposite side of the
RS-232 and RS-485 ports (see Figure 6). Labels
COM1 and COM2 correspond to the software
configuration of the COM ports. LEDs show, transmit,
and receive activity for the serial ports and optional
modem.
Note: You must remove the cover to see the serial
port LEDs. See Removing and Replacing the Cover.
The yellow Transmit LED indicates that the
FX20/FX60 is sending data out the serial port over
a communications line to a connected device.
The green Receive LED indicates that the
FX20/FX60 is receiving data from a connected
device.
These LEDs are driven by pulse detectors that provide
a fixed on-time sequence when data is detected on the
port. If the receive LED is on constantly, a problem
with the communications channel may be present,
such as a shorted wire or reversed wiring.
Niagara
AX
Software Installation
As shipped from the factory, FX20/FX60 are pre-
configured with a Niagara build, a license, and four
Johnson Controls® specific Java® Archive (JAR) files.
With these components in place, you only need to
change login credentials and IP settings (per network
requirements) when setting up the FX20/FX60. This
section provides step-by-step instructions for these
tasks.
The most straightforward way to set up an FX20/FX60
(and to upgrade to a newer Niagara build at a later
date) is to use the administrative tools available under
the Tools Menu in the FX Workbench software.
Note: If upgrading JAR files with patches at a later
date, use the Update Remote Site menu item. If
upgrading to a newer Niagara build, use the Upgrade
Remote Software Version menu item. If changing login
credentials, use the Change Remote Login Credentials
menu item.
Preparing for Setup
Providing Power and Connectivity
Perform the initial startup of an FX20/FX60 in your
office before physically mounting it in place at a job
site.
After you complete the commissioning process, mount
and wire the FX20/FX60 at the job site, making
permanent mounting and wiring connections.
For this initial Ethernet connection, you can use one of
the following:
a crossover cable connected directly between your
computer and the FX20/FX60
a standard Local Area Network (LAN) connection
in which your computer and the FX20/FX60 are
physically connected to the same Ethernet hub or
switch
