■
Memory Address:
Indicates the memory mapped address that is assigned to the
selected NIC. This value can never be zero.
■
PCI Bus Mode:
Indicates the type and mode of PCI bus slot that is occupied by the
selected NIC. The possible values of this parameter are:
PCI 33MHz 32-bit bus
PCI 33MHz 64-bit bus
PCI 66MHz 64-bit bus
PCI-X 100 MHz 64-bit bus
■
Network Status:
Provides overall status of the following:
■
Link Status OK—When GREEN, it indicates there is a link established at 10, 100, or
1000 Mbps. When RED, it indicates that a link is not established.
■
Receive OK—Indicates the selected NIC is able to receive data (gigabit only).
■
Transmit OK—Indicates the selected NIC is able to transmit data (gigabit only).
Diagnostics
The Diagnostics screen allows you to view information for 3Com NICs.
This function is used to test the physical NIC components.
Interface components of the Diagnostics window are described below:
■
Control Register Test:
Verifies the read and write capabilities of the network
controller registers by writing various values to the registers and verifying the result.
The device driver uses these registers to perform network functions such as sending
and receiving information. If the test fails, the network NIC may not work properly.
■
MII Register Test:
Verifies the read and write capabilities of the physical layer chip
registers. The physical layer chip is used to control the electrical signals on the wire
and for configuring network speed, such as 1000 Mbps.
■
EEPROM Test:
Verifies the content of the EEPROM by reading a portion of the
EEPROM and computing the checksum. The test fails if the computed checksum
differs from the checksum stored in the EEPROM. An EEPROM image upgrade will
not require a code change for this test.
■
Internal Memory Test:
Verifies that the network controller internal memory 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 network controller will
not function without its internal memory.
■
On Chip CPU Test:
Verifies the operation of the two internal CPUs in the network
controller.
■
Interrupt Test:
Verifies that the NDIS driver is able to receive interrupts from the
network controller.
■
MAC and PHY Loopback Test:
Verifies that the NDIS driver is able to send packets
and receive packets from the network controller. (See “DOS Diagnostic Failures” on
NOTE:
Only NICs with a 1000 Mbps link will light the Local Receiver/Remote
receiver LEDs.
NOTE:
Parameters (3 thru 10) are not applicable on other vendors' NICs and
these values are displayed as: Information Not Available.
NOTE:
Network connection will be lost when running these tests.
