The THS4086 HDEC Series 4U Rackmount Computer

The THS4086 HDEC Series 4U Rackmount Computer

An HDEC Series midsize format backplane forms the backbone of the THS4086 HDEC Series 4U rackmount computer.  The brain of the THS4086 is an innovative HDEC Series system host board such as Trenton’s HEP8225 featuring two, long life, Intel® Xeon® E5-2600 v3 processors.  The most compelling part of the system architecture is the built-in capability to support as many as eight PCI Express plug-in cards without the need of expensive PCIe switches.  This system design feature reduces system cost while increasing available bandwidth in order to produce the most efficient high density embedded computing systems possible.

HDEC Series system host board and midsize format backplane


The THS4086 is an HDEC Series 4U rackmount computer that features four 3.5″ drive bays that may be populated with up to eight HDD/SDD storage drives. Innovative HDEC Series board technology is at the heart of the THS4086 system. The system’s base configuration includes the dual-processor, HEP8225 system host board and the HDB8228 HDEC Series midsize format backplane. This 19″ industrial rackmount computer features a rugged, lightweight, aluminum chassis design with an impressive 16.5″/419mm shallow chassis depth. Power supply options include a fixed, single ATX/EPS or rear-removable redundant power supplies.



System Fan Control

The HDEC Series system host board and backplane utilized in this rackmount computer design control and monitor tach pulses from the system fans. The SHB and backplane’s fan controller circuitry also accepts fan speed commands (including on/off) and provides individual pass/fail fan status via the SHB’s I2C interface. Fan speed can also be based on temperature via the rackmount computer’s built-in thermal sensors.

Drive Bays

• 4 -3.5″ front bays can be configured to support up to 8, 2.5″ front removable/hot swap HDD/SDDs
• 1 – Slim-line optical media bay

Data Storage Capacity

The maximum system storage capacity is drive type, individual drive capacity and system configuration dependent.  The THS4086 supports up to 4, 2.5″ 15mm or 3.5″ drives, or, 8, 2.5″, 9.5mm thick drives in front access drive carriers.  THS4086 systems configured with 1TB HDDs could provide a storage capacity of up to 8TB, and about 3TB of storage capacity when using 2.5” SSDs.

Note: Maximum system storage capacity will increase as HDD/SDD storage capacity increases.

Power Supply

Rear-mounted power supply options are available in the THS4086 and they include:
Fixed, ATX/EPS up to 860W
– OR –
Redundant, ATX up to 800W


2 -120mm Fans (front access/hot swap), 210 CFM each
