The PMC-8246 is based on the Intel 82546GB dual port Gigabit
Ethernet controller. The Intel 82546GB is a highly integrated chip,
includes Ethernet MAC, PHY, and provides PCI-X 133MHz capa­bility. Please refer to the Intel 82546GB datasheet for more infor­mation on the GbE ports.

The PMC-8246’s bypass capability uses a mechanical relay array
to control the physical routing of the GbE signals. There are two
communications states for the GbE signal routing: 1) Normal
State, 2) Bypass State. Please refer to section 1.4 for block dia­grams of the two states.

Introduction 1

Watchdog timer (WDT) and bypass control logic circuits are used
to control the relay and communication states. The programmer
can control those functions via the Software Definable Pins (SDP)
on the Intel 82546GB by programming its registers. Please refer to
section 1.5 for a block diagram of the bypass control circuits.

1.4 Communication States

The following diagram illustrates the Normal State: where the two
GbE signals are straight-through connected to the GbE ports via
the transformers. The two GbE ports work independently as nor­mal dual GbE ports.

3.3 DOS Utilities for Evaluation - Utilities List

Before programming this card, users can evaluate the PMC-8246
bypass capability using the DOS test utility - 8246util.exe:

8246util e [x]:

Enable the WDT. Users can determine the time out value by typing
the parameter [x]; only 1, 2, 4, or 8 is valid for [x]. If the user does
not reload the WDT before time out in 1, 2, 4 or 8 seconds
depending on the setting, then the relay array will be switched to
the Bypass State. A ‘click’ can be heard when the relay switches.

8246util d:

Disable and stop WDT. The relay array will stay in the same state.

8246util w:

Enable WDT and keep reloading WDT. The WDT would keep run­ning unless the program stops running or powers off.

8246util n:

Enforce the relay array to Normal State and WDT will be disabled.

8246util b:

Enforce the relay array to Bypass State and WDT will be disabled.
