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
FIGURE 1-2 . An explanation of the LEDs is given 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.
