Note
The network connection is temporarily lost when the diagnostic tests
are running.
Figure 7. Diagnostics Tab
The Diagnostics tab contains the following fields:
Control Registers. This test verifies the read and write capabilities of
the network controller registers by writing various values to the
registers and verifying the results. The device driver uses these
registers to perform network functions such as sending and receiving
information. If the test fails, the device may not work properly.
MII Registers. This test verifies the read and write capabilities of the
registers of the physical layer (PHY). This field is not displayed for fiber
adapters.
EEPROM. This test verifies the content of the electrically erasable
programmable read-only memory (EEPROM) by reading a portion of
the EEPROM and computing the checksum. The test fails if the
computed checksum is different from the checksum stored in the
EEPROM. An EEPROM image upgrade does not require a code
change for this test.
Internal Memory. This test verifies that the internal memory of the
device is functioning properly. The test writes patterned values to the
memory and reads back the results. The test fails if an erroneous value
is read back. The device cannot function without its internal memory.
