Has anyone ever seen the fiber version of the E30xx cards? Tell Us!

Based on content by William R. Walsh (original HERE).

Cabletron E3010

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.

CR1-4 Status LEDs - Link/TXD-RXD/UTP Polarity Reversed/Collision
SW1 AUI/TP Select - up for AUI, down for Twisted Pair

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?

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".)

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.

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.

Parts in grey are not populated on this adapter. Most are for a coaxial version of this card.

The E3100 board appears to be a "shared RAM" type...

Windows Compatibility

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.)
