Tactical Communication Server Unit

The TCSU or Tactical Communication Server Unit is provided in a conduction cooled 3-MCU ATR chassis, which supports up to two SBCs, one dedicated Software Radio Board and a Ritec power supply. It is the ideal Edge Server with the highest levels of Cyber Security designed in from the bottom up.  Each SBC can hold two PMC mezzanine cards. This configuration offers an IDM, a 1553 and an Ethernet Switch. The chassis is completely sealed and filtered for discreet applications. Conduction cooling is a strong-suite for Ritec boasting the most Watts dissipated in a conduction cooled chassis with as much compudensity. The TCSU is great for thin-air applications being fully capable of performing in the stratosphere for long duration missions. It is also loaded with plenty of Gigabit Ethernet and a very robust self-contained power supply that utilizes 28 Vdc input power. The SBCs utilize fast and powerful 4, 8 or 12 core processors with upto 32 Gigabytes of DDR4 RAM and upto 64 Gigabytes of NAND flash memory. GbE over copper, serial, and USB I/O interfaces are provided through a single ARINC 600 Series, Size 2 connector, with the Gigabit Ethernet ports provided through a Quadrax connection. A custom cPCI backplane is incorporated that provides two 6U SBC slots, one Software Radio Board (SRB) slot, and one power supply slot. The equipment is constructed using environmental management techniques that protect internal components from the effects of shock, vibration, and electromagnetic interference. The TCSU is designed for deployment in manned/unmanned rugged environments on airborne, shipboard, or ground-mobile platforms. The TCSU has the option of working with a proprietary maintenance lid to make accessing the unit with an additional Ethernet or a keyboard, mouse and display available without removing it from its installation.
