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

page 62. For safety warnings in Spanish see “Advertencias de seguridad para la instalación (Warn-

ings in Spanish)” on page 63.

connect cables.

4. Copper Cable Connecting/Disconnecting

Some copper 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 spe-

cial warnings and instructions.

5. Equipment Installation

This equipment should be installed, replaced, or serviced only by trained and qualified

personnel.

Disposal of this equipment should be in accordance to all national laws and regula-

tions.

Equipment Disposal

This equipment should be installed in compliance with local and national electrical

codes.

2 Adapter Card Interfaces

2.1 I/O Interfaces

Each adapter card includes the following interfaces:

• QSFP ports

• PCI Express x8 edge connector

• I/O panel LEDs

•I

C-compatible connector (for debug)

For dual port cards, port 1 connects to connector 1 o

f the device, while port 2 connects to connec-

tor 2 of the device.

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.

ConnectX®-2 VPI Single and Dual Port QSFP InfiniBand and Ethernet Adapter Card User Manual Rev 1.6

Mellanox Technologies

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

C-compatible interface. See

Appendix A,“Specifications,” on page 44 for the location on the board.

C Connector

ConnectX®-2 VPI Single and Dual Port QSFP InfiniBand and Ethernet Adapter Card User Manual Rev 1.6

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

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.
