Chapter 7: FC972 Remote 63
SNMP Operation
The FC972's SNMP agent polls the system and generates status information. Modules are polled continuously and the status in-
formation is condensed for the entire frame. An external monitoring tool (SNMP Manager) may poll the SNMP agent based on
the Modular I/O Audio MIB (Management Information Bases). The MIB and associated document can be received upon request.
The SNMP manager can also sit and wait to receive Traps from the SNMP agent and poll the frame afterward. The procedure de-
pends on the implementation of the management tool. For generic monitoring applications, the Modular I/O frame may be
equipped with GPIO module(s). In this case, the system can fire GPOs (relay closures) based on the settings made in the previous
section.
Operational Hints
Website display relies on data received by the browser from the web server of the communication processor on demand (i.e. it
polls the web server). The polling process is divided into time slices of different priorities and the browser content is not updated
automatically for all areas. Therefore, a manual reload is recommended to update the current state of the parameters displayed
in the GUI.
If a module dies or is removed from the frame, the module’s graphic turns red (see below).
The red graphic can only be cleared by inserting a good module. If the module is permanently removed, reset the FC972 Remote
by briefly pressing the Init button on the front panel, REBOOT from the web interface, or select REBOOT from the serial interface
menu. Then reload the browser content.
The browser session with the web server of the FC972 Remote may sometimes expire. In this case, Java Script at the browser site
may still work but no commands are accepted by the web server. Opening the serial console interface may display a message sim-
ilar to this:
Authorization failure for request “GET / ……” by user 'anonymous', required privileges are 'administer', but user's privileges are none.
Close and restart the browser to open a new session.
To change some parameter values, the GUI may use a slider. After clicking on an input field, move the slider with the mouse
pointer, keyboard arrow keys, or by the mouse wheel, which scrolls vertically if active.
SNMP Trap Configuration
The new module must be of the same type and have the same CAN address as the one removed. If a different module type is used
with the same CAN address, reboot the Frame Controller!
