Military Computer Chassis. Two separate processor boards in a MIL-STD-810G and MIL-STD-461F approved 4U chassis



  • TMS4710 is a short-depth 4U military computer chassis made for applications that require two separate computers in a 4U height and a maximum 23″ depth requirement (24.8" including rear chassis enclosure handles).
  • Rugged yet lightweight, it tolerates a remarkable shock value of 40G with the use of MIL-DTL-38999 and MIL-STD-1553 rear I/O connectors.
  • TMS4710 rackmount computer chassis has two front-accessible 3.5" drives and supports two separate processor boards with either dual Xeon or single Core series CPUs with up to 4 PCIe slots per processor (8 total).
  • All internal cabling is customized and secured to the chassis to optimize airflow and system cooling. The US-made military grade computer chassis is built to survive and comes standard with anti-corrosion coating.



Model TMS4710
Board Type One single or dual-processor system host board and one small form factor shoebox backplane per TMS4710 system segment.  Two total SHBs and backplanes.
Description The TMS4710 is a two-in-one 4U rackmount military computer with a specific SHB and backplane base configuration consisting of two, BXTS7059 SHBs and BPC8114L backplanes certified to MIL-STD-810G environmental and MIL-STD-461F electrical emissions standards.  Other “designed-to-meet” TMS4710 SHB and backplane configurations are available with alternative single or dual-processor SHB and shoebox backplane options offering extended PCI Express and PCI-X/PCI option card support.  Flexible data storage configurations via one internal and one front access drive bays are available.  Other system features include rear access, independent power supplies and support for MIL-STD-1553B ARINC 429 external I/O connections.
Depth 23″/584mm base chassis, 24.8″/630mm including rear chassis enclosure handles

System Fan Control Trenton’s FSC1400 simultaneously controls and monitors tach pulses from up to four system fans.  The controller also accepts fan speed commands (including on/off) and provides individual pass/fail fan status via an I2C interface to the computer’s PICMG 1.3 system host board.  Fan speed can also be based on temperature via the provided thermal sensor.
See the FSC1400 System Fan Speed Controller datasheet for additional details on system fan control operation.
Drive Bays Each TMS4710 SHb segment includes: 1 – Front access drive bay configured to support 1 – 2.5″ front removable/hot swap SDD or HDD
1 – Internal drive bay configured to support 1 – 2.5″ SDD or HDD
1 – Slim-line optical media bay
Data Storage Capacity The MIL-STD-810G/MIL-STD-461F base configuration supports a total of four, 240GB SSDs (2 per SHB segment) for a total system-wide SLC memory capacity of 960GB. Other HDD and SDD options and system storage configurations are supported.  The maximum TMS4710 data storage capacity depends on the drive type and individual drive capacity selected.
