I/O Interfaces

The IB-HCA includes the following interfaces:
Two 4x InfiniBand copper connectors
■
PCI-X 64-bit 133 MHz edge connector
■

InfiniBand Interface

The IB-HCA provides two 4x InfiniBand v1.1 connector (or ports) for external
copper cables and is IBTA specification 1.1-compliant.

PCI-X Interface

The PCI-X bus is a PCI-X version 2.2-compliant 64-bit 133 MHz interface. The
adapter can be either a master initiating the PCI bus operations or a slave
responding to PCI bus operations. The PCI/PCI-X bus can connect to a host CPU in
an HCA application.

LED Displays

Two InfiniBand ports connectors are located on the front panel of the adapter. Each
port has two LEDs, as shown in

Color Meaning
Green Physical Link – The physical link LED illuminates once the Tavor
driver is successfully attached to the port.
Amber Logical Link – The logical link LED illuminates once the InfiniBand
port is in the Up state. This LED also blinks when there is traffic on
the port.
