Columbus, Ohio - Tracewell Systems Inc.'s System Management Module (SMM) is an intelligent monitoring board that is programmable for full-system monitoring capabilities. The unit serves as a standalone, platform-independent module that is being integrated into the company's standard and custom system chassis.
The SMM is able to monitor critical system elements, which include voltages, temperatures, current and fan speed. It can report present status and alarm conditions via RS-232, Ethernet and I2C communications links, plus VFD/LCD or LED output.
The RS-232 and Ethernet interfaces allow the SMM to be connected to any processor board via a standard port. An I2C interface is provided for implementations requiring system management using IPMI protocol and for communication with optional peripherals.
In the past, that set of functions was typically assembled from a collection of dedicated boards wired together, instead of one microprocessor-based device that measures 5 x 1.5 x 1 inch.
Similar functionality from other suppliers would cost about twice the SMM's low price and lack its flexibility, according to the company. All of the board's functions, including voltage ranges and function of I/O ports, are preprogrammed at the factory per customer requirements.
The unit provides a set of inputs and outputs that can be augmented with satellite boards for additional functionality. The base board can monitor up to eight points for over- and undervoltage (values set by software), up to four fans, up to three temperature sensors and dc-OK and ac-OK inputs and other digital inputs. Outputs include one multi-purpose LED indicator output, up to two open-collector outputs and one form C relay output. Bidirectional inputs and outputs include up to two I2C serial ports, one RS-232 port and eight general-purpose I/O ports.
Optional peripherals include speed control for up to 16 fans (four fans per device), a 10/100-Base-T Ethernet controller, a current monitor (up to four voltages per device), a remote temperature sensor interfaced via I2C and a choice of VFD or LCD display.
Tracewell's SMM typically adds $495 to the price of a system and is available now.
