1.3 Finding the GUID/ MAC and Serial Number on the Adapter Cards
Each Mellanox adapter card has a label on the print side that shows the card serial number, the card
MAC for Ethernet protocol, and the card GUID for InfiniBand protocol. VPI cards have both a
GUID and a MAC (derived from the GUID).
Figure 3: Card Product Label
Port 1 uses the GUID or MAC ID described on the label. For Port 2 GUID or MAC
add 1 to Port 1's respective values.
1.4 Safety Warnings
For safety warnings in French see Avertissements de sécurité d’installation (Warnings in French)”
on page 60. For safety warnings in German see “Installation - Sicherheitshinweise (German)” on

attached to or detached from the connectors. Refer to the cable manufacturer for spe-
cial warnings and instructions.
5. Equipment Installation
This equipment should be installed, replaced, or serviced only by trained and qualified
personnel.

2.1.1 InfiniBand Interface
The ConnectX®-2 adapter card is compliant with the InfiniBand Architecture Specification, Release
1.2.1.
VPI adapter cards listed above, based on this device, provide access to its network ports by
means of QSFP connectors.

2.1.2 Ethernet Interface
The ConnectX-2 adapter card is compliant with the IEEE Std 802.3. The VPI adapter cards listed
above, based on this device, provide access to the Ethernet ports by means of QSFP connec-
tors.The Mellanox QSA (QSFP to SFP+) adapter modules can be ordered through Mellanox T
ech-
nologies authorized dealers.
2.1.3 VPI Port Configuration
VPI ports are auto-sensing but can be manually configured using a script.

2.1.4 PCI Express Interface
The ConnectX®-2 adapter cards support PCI Express 2.0 (1.1 compatible) through an x8 edge
connector. The device can be either a master initiating the PCI Express bus operations or a slave
responding to PCI bus operations.

2.1.5 LED Assignment
There are two I/O LEDs per port, green and yellow, located on the I/O panel. Table 8 outlines the
different LED functions.
Figure 5: LED - Port Association
Table 8 - Physical and Logical Link Indications
LED Function
Green - Physical link
Constant on indicates a good physical link
Blinking indicates a problem with the physical link
If neither LED is lit, then the physical
link has not been established
Yellow -
Logical (data activity) link
A constant yellow indicates a valid logical (data activity) link without
data transfer.
A blinking yellow indicates a valid logical link with data transfer
If only the green LED is lit and the yellow LED is of
f, then the logical
link has not been established.
The short bracket has the same port and LED footprints as the tall bracket.
2.1.6 I

C-compatible Interface
A three-pin header on the adapter card is provided as the I
2
C-compatible interface. See
Appendix A,“Specifications,” on page 44 for the location on the board.

2.2 Power
All adapter cards receive 12V and 3.3V power from the PCI Express Edge connector. All other
required power voltages are generated by on-board switch mode regulators. See “Specifications”
on page 44.
2.3 QSFP Power Level
The card supports power level 3, according to SFF Committee SFF-8436 Specification for QSFP
(Quad Small Form-factor Pluggable) Transceiver.
2.4 Memory
The adapter cards support multiple memory devices through the PCI, SPI (Flash) and I
2
C inter-
faces.
2.4.1 System Memory
The adapter cards utilize the PCI Express interface to store and access IB fabric and/or Ethernet
fabric connection information and packet data on the system memory.
2.4.2 SPI (Flash)
Each of the adapter cards includes one 16MB SPI Flash device (M25P16-VME6G device by ST
Microelectronics) accessible via the Flash interface of the ConnectX®-2 VPI adapter card.
There is a jumper on each adapter card that indica
tes to the device whether an on-board Flash
device is to be used or not. Table 9 provides information on this ju
mper. See the appropriate sche-
matic in Appendix A,“Specifications,” on page 44 for the jumper location.
