Specification
The AMC-310 is a Systems Monitor Module for use within AMC's range of industrial rackmount computers, offering remote
control and monitoring capabilities. The SMM operation can be functionally separated into four categories:
1. Sensing monitors internal system operations and environments
2. Alarm generates email warnings when user defined thresholds are met or errors are detected
3. Control system power cycle/reset, activation of internal devices
4. Reporting remote monitoring via LAN
System status can be accessed for updates or alarm priority reconfiguration from a web-based URL.
Features
- Power supply monitoring of all internal voltage rails
- System Temperature monitoring
- Eight universal fan sense inputs
- Two TTL inputs or outputs
- Ethernet 10/100 interface
- Email alarm generation
- Soft power switch input
- ATX power supply control
- System reset
- Two RS-232 ports for module/system parameter configuration
- Capability of module expansion via SPI interface
- Dimensions: 114.3mm x 82.55mm
Operation
- On-board or user-supplied alarms are prioritised via user definable parameters stored locally in EEPROM. The parameters can be reconfigured using the web-based GUI or serial interface.
- Remote Programming allows Flash firmware upgrade via FTP protocol
- Motherboard Monitoring Redundancy is maintained by the use of separate LAN providing constant motherboard status information on component temperature, condition, failure, usage etc.

Operating Power
The AMC-310 is powered from system ATX +5V Standby.
Power Supply Monitoring
The SMM provides analogue comparator circuitry that monitors specific system and local power supplies. The system supplies monitored are +5V, +3.3V, +12V, -12V.
Fan Sensing
The AMC-310 provides 8 tacho sensing fan inputs.
Microprocessor
The ARM 7 processor runs ThreadX RTOS and is used to service the Ethernet.
RS-232 Interface
The serial communication channel is supported by two RS-232 interfaces. Either port can be used for SMM parameter configuration or for debug purpose. Either port can also be set-up to be used as an expansion bus (SPI), which allows add-on modules to be connected.
Ethernet Interface
The AMC-310 has a network interface via a RJ-45 connector.
Optional Modem
The SMM supports an optional modem having a dial-in/dial-out interface.
