The E-frame was designed with the high (and flexible) power and cooling requirements for VPX (VITA 46/48) systems.
However, any 3U or 6U backplanes can be used including VME/64x, VXS, CompactPCI, and other backplane architectures. The Type 39E Portable Tower has a carrying handle. The E-frame tower modular aluminum construction can support up to 21 slots at 0.8 in. or 17 slots at 1-in. pitch. There are front accessible test points and monitoring LEDs for all VME, VPX, VXS, and cPCI voltages including 3.3, ±5, ±12, ±24, and ±48 Vdc.
The E-frame features high-performance cooling with three 150-CFM fans under the card cage. The fans are speed controlled with fan-fail indication. A system monitor with remote monitoring via Ethernet capability is optional. The black-coated powder-coated finish of the E-frame enhances aesthetics. Other features include a rear ac PEM (Power Entry Module) with fuses, GND stud, and front-located ESD jacks. The unit also offers full RTM (rear-transition module) support.
