Table 2: LED overview
The NTB link LED is controlled by software. Both LEDs depends on GPIO registers initialized by EEPROM. An
incorrect EEPROM can cause dark LEDs. DIP-switch SWMODE set to 0000b will cause all LEDs to be dark.
More details on DIP-switch settings can be found below.
Use cases
The IXH610 card may be used in the following use cases. The use cases are summarized in Table 3 Adapter
use cases on page 10.
Use case A: Transparent IO
The Dolphin IXH610 HCA connects to any standardized PCI Express x8 downstream device. No special device
driver is required for the IXH610 card. Any device in the PCI Express IO system will operate using its standard
device driver.
Use case B - 2 Node configuration - NTB mode (unbalanced)
2 node unbalanced “NTB” mode- The Dolphin PCI Express IXH610 adapter connects to a remote upstream
subsystem (with root complex) that may have a transparent re-driver card only. This configuration is not
supported by Dolphin software.
