Configuring MicroVAX 3100 Ethernet (Stupid Network-HardwareQuestions)

Hello,

My company is moving to a new data center and I received this message:

"Also, all of the switches at [the new data center] are gigibit
switches and all the ports are set to AUTO. Therefore, server
settings for "Speed and Duplex" on the network cards should be set to
AUTO. If the server only has a 100MB network card, please inform the
network group."

I have some MicroVAX 3100 Model 80s, 95s, and one 90.

I have 2 types of transceivers:

MADGE LE 46T transceiver with redundancy (IEE 802.3 10 BASE T) which
has the following controls: Enable or Disable: SQE, MOD (T+, T), EXS,
PRI

CenterCOM(TM) 210T twisted pair tansceiver IEE 802.3 10 BASE T (MAU)

Questions:

What are these transceiver settings and how should they be set (mostly
how they should be set!) (They are all in the disable and T
positions.)

Why do I even need transceivers?

Is there anything configurable on the NIC? If so, what do I need to do
and how?

Is there anything I need to do except tell the network group it's 10
Mb/sec Ethernet?

Are there any duplex settings? If not, is it half or full?

Thanks!

AEF

My recollection...from about a decade ago when I last
had MicroVaxes...is that there were no duplex settings
on the Thinwire/10-Base-T transceivers, but that we
set the network switches to full-duplex. Yes, there
*is* a difference: you can run either half-duplex or
full-duplex over 10-Base-T (and other twisted pair),
but if the two ends don't match, there are difficult
to trace communications problems (that is, you
don't get a hard failure, just poor response with a
lot of retries, or similar).

10Mb Half.

They will have to find some intermediate box to mediate between the
hardware generations. A switch that does 10 and 100 perhaps.

Thanks Ian and Ken.

I'll be away for a while and may not have Internet access. I'll answer
any questions upon my return next week.

Ciao.
