- 68000 onboard processor
- DMA control
- 32-bit, 33 MHz PCI bus interface
- FDDI interface chipset
- IEEE address ROM
- Onboard, nonvolatile memory for firmware storage

PHY LED (Diagnostics)
||PHY connection complete
||PHY connection in progress (or no cable attached)
||If on after system boots, indicates port or Link
Confidence Test (LCT) failure; retry loop
If on before system boots, indicates self-test
|Green / Amber
||Alternating—(DEFPA-DA and DEFPA-MA only)
||Port disabled by management or LED or adapter fails
- Turn on power to the computer and observe the PHY LED.
- Note the following events (within 10 seconds after the computer power is
- The PHY LED flashes green (three flashes) for approximately 1 second.
- The PHY LED turns off when the adapter passes the powerup self-test.
A steady amber LED indicates a powerup self-test failure.
