Cabletron MCA Network Interface Cards (10baseT, 10base2, Fiber)
Has anyone ever seen the fiber version of the E30xx cards? Tell
me!
Cabletron E3100

coaxial version of this card.

Yes, I know there are two "T2" entries on the outline above. Maybe I will even fix it. Blame the folks who can't label a PCB with component IDs. All component IDs are made up except for U7 and U23. Both of those items are shown with their correct component IDs.
Total Hardware '99 disagrees regarding the red and yellow LEDs. Red is claimed to indicate collisions, yellow the transmission of data. I think I've got it right, but who knows this many years later?
Fuse
The function of F1 (fuse) appears to be protection against too much current draw through the AUI port. It is socketed, so you can replace it with another 2AG fuse. Just be sure you've solved the overload problem first, otherwise you may risk damage to the board traces from prolonged or repeated overcurrent conditions. (The linked PC Magazine article says the fuse is for "for extra protection of transient voltages that might, through accident or miswiring, be imposed on the LAN wiring".)

Sorry folks, nearly all the component IDs are made up. I'd guess the actual IDs are hidden under the components, and I'm not about to unsolder them. This is more or less a TP cable version of the E3020.
Enterasys says the following about the SQE Test setting:
The Signal Quality Error (SQE) Test Switch allow you to enable
or disable the SQE ("hearbeat") internal test function on the
DNI Card. You generally disable the SQE, unless you are checking
the validity of the SQE Test. The SQE Test signal does not leave
the card. If the DNI Card is attached to the network through the
AUI port, the SQE should be set in the external transceiver. The
SQE is disabled when the card is shipped.
Total Hardware '99 disagrees regarding the red and yellow LEDs. Red is claimed to indicate collisions, yellow the transmission of data. I think I've got it right, but who knows this many years later?

Experiences
I've used this card in a Model 53SLC2 for some time with good results. The built in Windows 95 drivers run the card well and are reliable.
Windows
All of the Cabletron Ethernet adapters I have (E3010, E3020,
E3100) perform well under Windows 95 and 98 with the available
or included drivers. Windows NT doesn't appear to be supported
(unless there are built in drivers, which there are not for the
E3100 models) beyond version 3.5. Loading the NT 3.5 drivers
results in the message "a device attached to the system is not
functioning" in the event log. (This could be a by-product of
the slot counting bug, first fixed in Service Pack 3 for NT4.)
The E3100 board appears to be a "shared RAM" type...

Setting the Clock Source Jumper JP1
In most computers,
the DNI Card will use its own clock source (asynchronous mode).
If the DNI Card uses the system's clock
source, the board runs in synchronous mode.
Set the bus timing jumper as follows:
Place the shunt over pins 1 and 2 to use asynchronous clock
source (default setting). Model 50 compatibility)
Place the shunt over pins 2 and 3 to use a synchronous clock
source (Model 70 and 80 compatibility)
