2.2.1 Safety Warnings
el
la
The HCA Adapter cardshould not be operated in an area with an ambient temperature exceeding the maximum
recommended temperature of 55°C. Moreover, it requires an airflow velocity of 200LFM (linear feet per minute)
at this maximum ambient temperature.
M
During Lightning
During periods of lightning activity, do not work on the equipment or connect or disconnect cables.
Copper InfiniBand Cable Connecting/Disconnecting
Copper InfiniB cables are heavy and not very flexible. As such they should be carefully attached to or detached
from the connectors. Refer to the cable manufacturer for special warnings/instructions.

3 Driver Software and Firmware
3.1 Driver Software
For Linux, download and install the latest OpenFabrics Enterprise Distribution (OFED) software package available
via the OpenFabrics Web site at http://www.openfabrics.org. Follow the installation instructions included in the
download package.
ie
s
For Windows, download the appropriate software from https://docs.mellanox.com/dm/WinIB/ReadMe.html.
3.2 Updating HCA Card Firmware
og
Each HCA card is shipped with the latest version of qualified firmware at the time of manufacturing. Firmware is
updated occasionally, and the most recent firmware can be obtained from http://www.mellanox.com through the
‘Firmware’ downloads link. HCA InfiniBand cluster firmware update
3.3 Single HCA Card Firmware Update
hn
ol
•
Te
c
Firmware can be updated on the standalone single card using the flint tool of the Mellanox Firmware Tools (MFT)
package. This package is available for download, along with its user’s manual, from the single HCA card firmware
update page. See http://www.mellanox.com under ‘Firmware’ downloads.
no
x
A firmware binaries table lists a binary file per HCA card. The file name of each such binary is composed by combining the firmware name, the firmware release version, and the card part number.
la
Note: Please contact your assigned Field Application Engineer if you cannot find the firmware binary for
your adapter card. This may happen if the product is not yet available for general distribution.
el
3.4 HCA Card Firmware Update as Part of a Cluster Firmware Update
M
If the HCA card is part of an InfiniBand cluster, its firmware can be updated as part of the entire cluster firmware
update1, using the ibfwmgr tool of the IB administration (IBADM) tools package. IBADM is available for download
from http://www.mellanox.com, through the Management Tools download link. Check the ‘Firmware’ downloads
link for cluster update instructions.
1. Currently, only the Linux distributions support updating firmware for an entire InfiniBand cluster.

4.1.1 InfiniBand CX4 Interface
hn
ol
The ConnectXTM IB (MT25408) device is compliant with the InfiniBand Architecture Specification, Release 1.2. It
has two compliant 4X InfiniBand ports, 1 and 2, each having four Tx/Rx pairs of SerDes. Each of the HCA cards
(listed in Table 3 on page 8) based on this device provides access to these ports by means of two 4X InfiniBand connectors for external InfiniBand copper cables, also compliant with the IBTA specification 1.2. Connector 1 connects
to port 1 of the device, while connector 2 connects to port 2.

4.1.2 Each of the HCA cards is embedded with a ‘media detect circuit’ that supports active cables and external
InfiniBand fiber solutions to be connected to the InfiniBand port connectors. Fiber Solutions require the use of active
media converters.

4.1.3 PCI Express Interface
The ConnectXTM IB HCA Adapter cards support the PCI Express 2.0 x8 interface, 1.1 compatible. The card can be
either a master initiating the PCI Express bus operations or a slave responding to PCI bus operations.
4.1.4 LED Assignment
s
The board has four LEDs located on the I/O panel - 2 LEDs per 4X port. The green LED, when lit, indicates that the
InfiniBand driver is running and a valid physical connection between nodes exists. The yellow LED when lit, indicates a valid data activity link, this is the logical link. The yellow LED illuminates when the InfiniBand network is
discovered over the physical link. A valid data activity link without data transfer is designated by a constant yellow
LED indication. A valid data activity link with data transfer is designated by a blinking yellow LED indication. If the
LEDs are not active, either the physical link or the logical link (or both) connections have not been established.

A three-pin header on the HCA card is provided as the I2C compatible interface.See Figure 4 on page 22 for the location on the board.
4.3 Power
All adapter cards receive power from the PCI Express Edge connector. All other required power voltages are generated by on-board switch mode regulators. For power consumption see Specifications starting on page 22.
4.4 Memory
The HCA adapter cards support multiple memory devices through the PCI Express, Flash, and I2C-compatible interfaces.

4.4.1 System Memory
Each of the HCA adapter cards utilizes the PCI Express interface to store and access IB fabric connection information
and packet date on the system memory.
4.4.2 Flash
Each of theHCA adapter cards includes one 2MB SPI Flash device (P/N M25P16-VME6G by ST Microelectronics)
accessible via the Flash interface of the MT25408 ConnectX IB device.
There is a jumper on each adapter card that indicates to the device whether an on-board Flash device exists (or is to be
used). Table 7 provides information on this jumper. See Figure 4 on page 22 for the jumper location.

4.4.3 EEPROM
Te
c
Each board incorporates an EEPROM that is accessible through the I2C-compatible interface. The EEPROM is used
for storing the Vital Product Data (VPD). The VPD format adheres to the PCI Local Bus specification rev 2.3 VPD
definition (see “VPDs” on page 15). The EEPROM capacity is 512 bytes.
The PCI VPD (Vital Product Data) layout for each of the described Mellanox Technologies ConnectXTM IB
HCA Adapter cardscomply with the format defined in the PCI 2.3 “A1” was used as the HCA card (PCB) revision. Later revisions of the HCA card will have the same format.

Prior to assembling the short bracket, you need to apply a Kapton® polyimide round label on the board’s Print Side.
Note: Check to see if the label is already installed as this label may have been installed at the factory.
la
Note: The label can be provided by Mellanox Technologies (P/N: MEC000821).

The following steps are instructions for placing the polyimide label:
Make sure your working area is ESD protected.
