V8 – 8U Rackmount – 21 Slot System

For rackmount applications that need to accommodate up to the maximum 21 slots of 6U x 4HP card space available within the 19” rack format, the Verotec V8 chassis provides an ideal solution in a compact 8U enclosure. Based around our KM6-II Eurocard subrack, the system can be specified with a range of power supply and backplane options. Cooling is provided by a removable fan tray housed behind a hinged 2U front panel. This panel is vented for cooling and also features the status indicators and switches as well as an ESD point. The power supply is an embedded type, mounted on the rear drop down panel. A separate 3U rear panel allows access for cable management or to house additional components. With the total 84HP available, this system can take the full range of VME backplanes – from 5 to 21 slots and of course Verotec also offers a wide range of other bus architectures and slot options.

Thermal Management

Effective cooling is provided by a combination of three 120mm fans arranged in a removable fan tray mounted directly below the cardframe, drawing air through a filtered and vented panel at the bottom front of the chassis, up through the cards and exhausted through a vented top cover. When powered by an embedded PSU attached to the rear panel, the supply is directly cooled by its own internal fan, venting from side-to-side. All fans are DC powered from the autoranging power supplies and are capable of providing sufficient airflow to dissipate the large amount of heat generated by the latest CPU boards.

Power Supply

There is a choice of rear mounted power supplies; available as either 700 or 1000W output units, mounted on a 5U hinged rear panel, offering easy access to the PSU and to the rear of the backplane


Proven practices have been adopted in the design of the chassis. The cards are housed in Verotec’s IEC 60297-3 compliant KM6-II conductive subrack, and chassis vent patterns have been designed to allow maximum airflow while still maintaining shielding effectiveness. An earth bonding point is provided on the front panel for a wrist strap connection to ensure ESD protection when inserting or extracting boards.


V8 chassis incorporate a 6U Monolithic (J1/J2) VME backplane, compliant to the ANSI/IEEE Std 1014-1987 specification. All backplanes have on-board passive termination, auto bus-granting connectors and power bug / busbar power connections. Verotec offer a comprehensive range of backplane architectures – please contact your sales office if you have a special requirement.

Air Baffle Cards

The air baffle card is designed to be used in vacant system slots to both close the front panel area and block airflow. In doing so, cooling air is diverted to active cards, thus maintaining the correct system airflow profile.

Customizing Options

The scalable design enables options based on other 3U and 6U backplanes across all bus structures such as VMEbus, VME64x and cPCI very easily. Where the system is to be deployed away from users, a system monitor can be supplied to allow remote monitoring and control. With a wide range of options available, it would be impossible to list every combination. Should your application require a different specification such as backplane, cooling or power supply variants, please contact us to discuss.
