GENERAL INFORMATION
The VPX4810 series is a 3U VPX Non-Intelligent XMC/PMC carrier board designed for 4x/8x PCIe bus
connection. The carrier card uses a PLX Technology® PCIe Switch Chip (PEX 8624) and PLX Technology®PCIe to
PCI Bridge Chip (PEX 8114) to interface between the VPX bus and one XMC/PMC mezzanine I/O module card.
Model VPX4810 is an air-cooled product which can be used for front and rear I/O XMC/PMC mezzanine I/O
modules.
Model VPX4810CC is an extended temperature conduction-cooled product which supports all Acromag
FPGA modules. It only supports Rear I/O.
Model VPX4810REDI is a VITA 48 Ruggedized Enhanced Design Implementation (REDI) model that does not
support Front I/O and will only fit in REDI chassis.
Key Features
•PCIe x4 or x8 lane VITA 46.4 Backplane Compliance: The VPX4810 supports either a 4 or 8 lane PCIe 2.0
connection to the backplane.
•Supports either 1 PMC or XMC module –The VPX4810 supports 1 PMC module complaint to PCI 3.0 -- 32
or 64 bits at 33 or 66MHz or PCI-X 1.0b 64 bits at 66MHz, 100MHz, or 133MHz. Alternatively it supports
one XMC module compliant with PCI Express 2.0 up to 8 lanes.
•ESD Strip - The VPX4810 board has been designed to provide electrostatic discharge (ESD) capability by
using an ESD strip on the board.
•Injector/Ejector Handle - The VPX4810 uses a modern injector/ejector handle, which pushes the board
into the rack during installation and has a positive self-locking mechanism so it cannot be unlocked
accidentally. This handle is fully IEEE 1101.10 compliant and is needed to give leverage to install and
remove the board.
•EMC Front Panel - The VPX4810 uses the preferred EMC 1” front panel per VITA 48 specification.
•Conduction Cooled Frame - The VPX4810CC board has a custom conduction cooled assembly consisting of
a conduction cooled frame, thermo bars, ejector/injectors and wedge-locks designed to thermally conduct
heat away from the Conduction Cooled XMC/PMC modules.
•REDI Frame - The VPX4810REDI board has a custom conduction cooled and full shield assembly complaint
to VITA 48.0. The assembly consists of a conduction cooled frame, thermo bars, ejector/injectors, wedge-
locks, and a full bottom and top face plate designed to thermally conduct heat from and to protect from
ESD the XMC/PMC modules.
•Compatible with OPEN VPX VITA 65.0
Software Support
The VPX4810 family of modules is intended to be used as a non-intelligent bridge between the system PCIe
bus and the XMC/PMC module. No software is required to operate the board. However all XMC/PMC modules
will require support drivers specific to your operating system. Refer to your XMC/PMC modules manufacturer
for information on PCIe drivers.

PREPARATION FOR USE
Unpacking and Inspecting
Upon receipt of this product, inspect the shipping carton for evidence of mishandling during transit. If the
shipping carton is badly damaged or water stained, request that the carrier's agent be present when the carton
is opened. If the carrier's agent is absent when the carton is opened and the contents of the carton are
damaged, keep the carton and packing material for the agent's inspection.
For repairs to a product damaged in shipment, refer to the Acromag Service Policy to
obtain return instructions. It is suggested that salvageable shipping cartons and packing
material be saved for future use in the event the product must be shipped. WARNING:
This board utilizes static sensitive components and should only be handled at a static-
safe workstation.
This board is physically protected with packing material and electrically protected with an anti-static bag
during shipment. However, it is recommended that the board be visually inspected for evidence of mishandling
prior to applying power.
Card Cage Considerations
Refer to the specifications section for loading and power requirements. Be sure that the system power
supplies are able to accommodate the power requirements of the system boards, plus the installed Acromag
board, within the voltage tolerances specified.
Each of Acromag’s VPX carriers are in a different pitch as determined by the cooling technique. The VPX4180 is
a 1.0” pitch board, the VPX4810CC is 1.0” pitch, and the VPX4810REDI is a 1.00” pitch board. Verify your
chassis compliance to accommodate the various board pitches.
In an air cooled assembly, adequate air circulation must be provided to prevent a temperature rise above the
maximum operating temperature and to prolong the life of the electronics. If the installation is in an industrial
environment and the board is exposed to environmental air, careful consideration should be given to air-
filtering.
IMPORTANT: Adequate air circulation of 100 LFM must be provided to prevent a temperature rise above the
maximum operating temperature in the VPX4810.
In a conduction cooled assembly, adequate thermo conduction must be provided to prevent a temperature
rise above the maximum operating temperature.
IMPORTANT: If the VPX4810CC is not installed in a conduction cooled chassis, air circulation of 200 LFM must
be provided to prevent a temperature rise above the maximum operating temperature in the VPX4810CC.
A REDI assembly must be installed in a REDI complaint chassis since conduction is the only method for cooling
the board.
IMPORTANT: The VPX4810REDI should not be operated under air cooled conditions.

Backplane
This board is design to work with a Backplane profile of BKP3-DIS06-15.2.7-n. Failure to use a
compatible backplane could result in damage to this product or others in the chassis. For more information on
backplane compatible please refer to the Acromag VPX4810 Compatibility Whitepaper.
WARNING: THE VPX4810 CAN ONLY BE USED ON A 3U BACKPLANE. PLUGGING THIS MODULE INTO
A 6U BACKPLANE MAY RESULT IN DAMAGE TO THIS BOARD DUE INCOMPATIBLE POWER SUPPLIES.
Non-Isolation Considerations
The board is non-isolated, since there is electrical continuity between the VPX bus and PMC module grounds.
As such, the field I/O connections are not isolated from the system. Care should be taken in designing
installations without isolation to avoid noise pickup and ground loops caused by multiple ground connections.
The model VPX4810 carrier field I/O connections are made through the rear via J4 for a single PMC mezzanine
I/O module card.
Jumper Settings
The VPX4810 has two jumpers for selecting the number of PCIe lanes used from the backplane and another to
control how the chassis ground is connected. Note that the jumpers are in the same location on each model
regardless of metalwork.

especially at Gen 2 link speeds. If the system does not provide a common clock then non-common clock mode
must be used.
