Functional Components
The major components on the adapter are as follows:
- 1 megabyte of packet memory
- 68000 onboard processor
- DMA control
- 32-bit, 33 MHz PCI bus interface
- FDDI interface chipset
- IEEE address ROM
- Onboard, nonvolatile memory for firmware storage
DC amps @ +5.0 V, 1.1 A - SAS UTP
DC amps @ +12.0 V, 0.1 A (maximum)
Bus loading - per PCI standard, Revision 2.0
PHY LED (Diagnostics)
| Color |
Status |
Condition |
| Green |
On |
PHY connection complete |
| Green |
Blinking |
PHY connection in progress (or no cable attached) |
| Amber |
On |
If on after system boots, indicates port or Link
Confidence Test (LCT) failure; retry loop
If on before system boots, indicates self-test
failure |
| Green / Amber |
Blinking |
Alternating—(DEFPA-DA and DEFPA-MA only)
|
None
|
Off
|
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
turned on):
- 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.
