• For Windows see WinIB ReadMe at https://docs.mellanox.com/dm/WinIB/ReadMe.html
• For Linux see Mellanox OpenFabrics Enterprise Distribution (OFED) software package available via the
Mellanox OpenFabrics Web site http://www.mellanox.com/products/ofed.php
Read all installation instructions before connecting the equipment to the power source.
This equipment should not be operated in an area with an ambient temperature exceed-
ing the maximum recommended5°C (°F). Moreover, to guarantee proper air flow, allow
at least 8cm (3 inches) of clearance around the ventilation openings.
During periods of lightning activity, do not work on the equipment or connect or discon-
nect cables.
Copper InfiniBand cables are heavy and not flexible, as such they should be carefully
attached to or detached from the connectors. Refer to the cable manufacturer for special
warnings and instructions.

3Driver Software and Firmware
3.1 Driver Software
For Linux, download and install the latest OpenFabrics Enterprise Distribution (OFED) software package available
via the Mellanox OpenFabrics Web site at http://www.mellanox.com/products/ofed.php. Follow the installation
instructions included in the download package.
For Windows, download the appropriate software from https://docs.mellanox.com/dm/WinIB/ReadMe.html.
3.2 Updating HCA Card Firmware
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.
3.3 Single HCA Card Firmware Update
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.
A firmware binaries table lists a binary file per HCA card. The file name of each such binary is composed by combin-
ing the firmware name, the firmware release version, and the card part number. 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.
3.4 HCA Card Firmware Update as Part of a Cluster Firmware Update
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.

Adapter Card Interfaces

Rev 1.2 Mellanox Technologies
4Adapter Card Interfaces
4.1 I/O Interfaces
Each HCA card includes the following interfaces:
• Two 4X InfiniBand Copper Connectors
• PCI Express x8 edge connector
• I/O panel LEDs
•I
2C compatible connector (for debug)
4.1.1 InfiniBand Interface
The ConnectX®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 InfiniBand connectors.
These cards are also compliant with the IBTA specification 1.2. Connector 1 connects to port 1 of the device, while
connector 2 connects to port 2.
Figure 2: Port Numbering
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 con-
verters.

Port 2

Mellanox Technologies
The cards can be either a master initiating the PCI Express bus operations or a slave responding to PCI bus opera-
tions.
4.1.2 LED Assignment
The board has four LEDs located on the I/O panel - 2 LEDs per 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, indi-
cates 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.
Figure 3: Physical and Logical Link Indications
Note: The short bracket has the same port and LED footprint as the tall bracket.
4.2 I2C Compatible Interface
A three-pin header on the HCA card is provided as the I2C compatible interface. See Figure 6 on page 26 for the loca-
tion on the board.
Figure 4: I2C Connector
4.3 Power
All adapter cards receive power from the PCI Express Edge connector. All other required power voltages are gener-
ated by on-board switch mode regulators. See “Specifications” on page 26.

4.4 Memory
The HCA cards support multiple memory devices through the PCI Express, Flash, and I2C-compatible interfaces.
4.4.1 System Memory
Each of the HCA cards utilizes the PCI Express interface to store and access IB fabric connection information and
packet data on the system memory.
4.4.2 Flash
Each of the HCA cards includes one 2MB SPI Flash device (M25P80 device 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 6 on page 26 for the jumper location.
4.4.3 EEPROM
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. The EEPROM capacity is 512 bytes.

The PCI VPD (Vital Product Data) layout, for each of the described Mellanox Technologies ®ConnectX IB HCA
adapter cards, complies with the format defined in the PCI 2.3 Specification, Appendix I. All ConnectX IB HCA
adapter cards share the same PCI VPD layout.“A1” was used as the HCA card (PCB) revision. Later revisions of the
HCA card will have the same format.
Note: “A1” was used as the HCA card (PCB) revision. Later revisions of the HCA card will have the same
