PARK RIDGE, ILL. - Elma Electronic Inc. (Fremont, Calif.) has rolled out a shelf management module, interface board, and development chassis for AdvancedTCA architectures.
The systems are said to be especially important for AdvancedTCA (advanced telecom computing architecture) because of AdvancedTCA's 48-volt redundant power and 200-Watt-per-board heat dissipation requirements.
"The cooling requirement (of AdvancedTCA) is more than doubled from standard CompactPCI and that's partially because the real estate is doubled," noted Ram Rajan, vice president of engineering for Elma Electronic. "That's the reason why this system takes on such importance. It needs to be able to detect over-temperatures and take corrective action."
Known as IPM Sentry and developed in conjunction with Pigeon Point Systems (Scotts Valley, Calif.), the new shelf manager helps deal with the higher heat and voltages inside the chassis by automatically adjusting the fan speeds to provide cooling at various locations. It is able to read thermocouple inputs and tachometer inputs for up to eight fans, and uses a pulsewidth modulated (PWM) to control fan speed.
"If there's a particular spot that's getting hot, it can sense that and tell the fans to speed up in that area," said Justin Moll, marketing manager for Bustronic Corp., a sister company of Elma. "That's a lot more efficient than having all the fans in the fan tray going off at the same time."
In addition to monitoring voltages and temperatures, the IPM Sentry maintains a system event log (SEL) along with a sensor data record (SDR), which can be accessed by the IPM controller. It also collects information on field replaceable units, such as hot swap peripheral boards, as well as sending out remote alarms via RS232 and 10/100 Ethernet.
Along with the shelf manager, the company has also rolled out a new interface board for the IPM Sentry that is designed to handle both AdvancedTCA and CompactPCI architectures. The interface board allows flexibility in terms of how and where the shelf managers are plugged into CompactPCI or AdvancedTCA architectures. Even if a dedicated slot on the backplane is not feasible, the company's engineers said, the new interface board allows the shelf manager to plug into the chassis.
The third part of the company's recent introductions is its 5U AdvancedTCA development chassis, aimed at prototyping and demonstrations.
The PICMG 3.0-compliant horizontal chassis features an AC input, so that the unit can be plugged directly into a conventional wall outlet. This provides a more favorable way of powering up the unit, as opposed to being limited to 48V DC power only, according to the company. With the AC input, the chassis can also be transported more conveniently for demonstrations. The 700W AC input PSU provides 48V at 15A.
The unit offers a unique 5-slot ATCA backplane that is also versatile for prototyping. Full Mesh, Replicated Mesh, and Dual Star topologies can be implemented on the same backplane. It also has options for plugging with the IPM Sentry Shelf Manager -- an advanced solution that goes beyond standard monitoring. On the side of the slots, the backplane has 2mm HM connectors for direct plugging the 3U x 160mm IPM Sentry Shelf Manager Carrier Card.
Side-to-side cooling is achieved via a plug-in fan tray with dual 170 CFM fans with PWM (pulse width modulation) control. The chassis is a 19" rackmount version with rugged steel construction. For serviceability, the filter tray and fan tray are separately removable.
Other chassis features includes a board mating receptacle (patent pending), which provides secure grounding, accurate alignment and accepts wide tolerances of the alignment pin spacing.
Pricing for IPM Sentry starts at under $1,500 with a 2-4 week lead time.
Pricing for the interface board is $125 with 2-4 week lead time.
Price of the development system ranges from under $3000 to over $4000, depending on options. Lead time is 6-8 weeks.
