Status Monitoring

Status Monitoring

There are a number of ways to monitor frame and module status. These
methods are summarized here. For more detailed information, refer to the
8900NET (Net Card) Network Interface Module Instruction Manual and the
8900 Gecko or 8900 GeckoFlex Frame Instruction Manuals.

All modular product documentation is available on-line in PDF format at
this link:

The main status monitoring methods include the following:

External frame alarm output on the rear of the 8900 frame with
reporting from the Module Health Bus and other frame status alarm
reports,

LEDs on the Frame, 8900NET module, and individual frame media
modules,

Web browser status reporting for each frame component, and

SNMP traps, captured by Grass Valley’s NetCentral or another SNMP
Manager Application.

Note

SNMP trap information is only available when an SNMP Agent has been
installed and configured.

External Frame Alarm

An external Frame Alarm output is available on pins 8 and 9 of the RS-232
connector on the rear of the frame. The Frame Alarm outputs a voltage
level indicating there is an alarm condition on the Module Health Bus or
one of the other frame components reported to the Frame Monitor module
in a Gecko 8900TF or GeckoFlex 8900FF frame or the 8900NET module in
an 8900TFN and GeckoFlex 8900FFN frame.

The Module Health bus is a separate line on the frame motherboard
that provides a means for older or less capable modules (such as DAs
with no microprocessor) that cannot communicate over the Frame
(serial) bus to report warning and alarm conditions to the external
Frame Alarm. All media modules in the frame report a voltage level to
this line when a warning condition occurs on the module. The specific
warning or module location is not reported, only an indication that an
warning condition has occurred.

Frame alarm reporting from other frame components can be enabled
and disabled using DIP switches on the Frame Monitor and 8900NET
module. For frames with an 8900NET module, the Frame Alarm
Reporting web page allows configuration of the alarms and warnings
that are reported to this external Frame Health Alarm.
