Pre-Installation Questions
Certain steps should be taken prior to installing the PXH842. You should determine the following configuration requirements.
•
Which PCIe slot and system will the card be installed in?
•
What is the speed and link width of the slot that the card will be installed in?
•
What is the operating environment in which the card will be installed?
•
What width and length of cables will be used?
•
Proper operational conditions, temperature, air-flow.
PCIe Slot determination
The PXH842 supports PCIe Gen1, Gen2 and Gen3 speeds and x1, x2, x4, x8 and x16 link-widths. The slot width and speed will affect
the performance of the card. The card can be physically installed in an x4, x8 or x16 connector. The card will auto configure to the
slot speed and width.
•
Install the board in a slot connecting directly to the CPU for optimal shared memory performance.
•
Install the board behind a PCIe switch in the IO system for optimal PCIe peer to peer performance (e.g. between GPUs,
FPGAs)
PXH842 Configuration
The PXH842 has a DIP switch bank to control the main configuration of the card. The DIP switch labeled SW1 can be found close to
the upper edge of the board. The default DIP switch setting is Transparent Host single link x16 operations. Alternative configuration
settings are one, dual or quad IO Expansion and target operation.
Operating environment
To maximize life time for the product and maintain the warranty, please honor the specified operating temperature and make sure
the specified air flow is present. Special care should be considered when PXH842 is used in office type cabinets in combination with
other high energy consuming PCIe devices, e.g. not active cooled GPUs (preliminary):
Operating Temperature: 0°C - 55°C (32°F - 131°F), Air Flow: 150 LFM
Operating Temperature with AOC: 0°C - 45°C (32°F - 113°F), Air Flow: 150 LFM
Relative Humidity: 5% - 95% (non- condensing)
TIP: After installing the Dolphin eXpressWare Transparent Board management software, you can use the tool dis_diag to determine
the actual board temperatures.
Cable Connections
The PXH842 utilizes the PCIe FireFly optical transceivers from Samtec. The card supports any length up to 100 meters without any
special PCIe tuning. The requirement for the fiber cable is:
MPT female, 24 pairs, OM3 50/125, Key up - Key up (Type C) cables.
A x16 link requires two identical cables. A x8 link requires only one cable.
