V9 – 9U Rackmount – 21 Slot System

The V9 chassis may be used either in rackmount applications, or alternatively as a stand-alone unit in the Diplomat enclosure. Offering the full width 19” chassis allows for the full 21 slots of 4HP cards, typically in VME64x or CPCI architecture systems. Cards are mounted in the KM6-RF subrack, recessed back to allow for front cable management. The subrack is fully IEEE 1101.10/11 compliant, with provision for rear transition modules to be accommodated. As an option, the front may be closed off with a hinged blank panel. In addition to a choice of backplanes, various power options are available – either embedded in the base of the unit, or as pluggable modules where the full 21 slots are not required. Cooling is provided by a removable fan tray housed behind a 2U front panel. This panel is vented for cooling and also features the status indicators and switches as well as an ESD point.

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 to the top-rear.. 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

The user has a wide choice of supplies; if the rack is not required to house the full 21 slots capability of boards, front mounted CPCI pluggable supplies may be considered. Two of these 6U supplies, rated at 500W each, can be used in a power sharing hot-swap mode for high-availability applications. Where the full backplane width capability is required, there is again a choice of embedded power supplies; available as either 700 or 1000W output units.


Proven practices have been adopted in the design of the chassis. The cards are housed in Verotec’s IEEE 1101.10 compliant KM6-RF conductive subrack, and chassis vent patterns have been designed to allow maximum airflow while still maintaining shielding effectiveness. Power is introduced though a filtered IEC inlet (also switched and fused) to minimise conducted noise. An earth bonding point is provided on the front panel for a wrist strap connection to ensure ESD protection when inserting or extracting boards.


Verotec has a comprehensive range of backplanes available, covering a wide range of slot sizes and bus architectures. The chassis shown is fitted with a 10 slot VME64x backplane; however other widths of VME64x or CPCI backplanes may be selected. Verotec offer a comprehensive range of architectures covering VME, VME64x, CompactPCI, PXI, VXS, VXI and VPX – please contact your sales office if you have a special requirement.

Extender Boards

Available with or without the centre P0 connectors, these 6U x 330mm multilayer extenders are for use in VME64x applications and are designed to bring cards out of a system for fault diagnostic or development work. Jumper links are provided on all signal lines for interrogation and an additional connector is fitted for connection to a logic analyser or termination module. Available separately is a metal frame to support the card and provide extraction functionality by two levers. CompactPCI versions are also available. Please consult the factory for ordering information.


A range of accessories are available including air baffle cards, disk drive mounting adaptors, filler panels and more – please contact sales office for further information

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.
