Hi,

The Sun Fire V240s that I have have 4 RJ45 connectors in a row, labelled
"0 1 2 3". Is there a fixed relationship between these connectors and
the "bgeX"?

The reason that I'm asking is that I was trying to do a Solaris
installation on one of them, where I had my ethernet cable plugged into
the connector labelled "0", and couldn't get it to work as "bge0". I
finally got it working, but had to plug the network cable into the
connector labelled "2".

On another V240, I was able to get bge0 working, but with the network
cable plugged into the connector labelled "0", so I'm a bit confused

...

The other question I had was what is "ce0"? Can I use "ce0" for copper
10/100 ethernet? If so, which RJ45 connector corresponds to this "ce0"?

For an installation where just a single ethernet connection is needed,
is the "normal" interface to use "ce0" or "bge0"?

Thanks in advance,
Jim

Hi,

I forgot to ask, what does the "<--->" symbol above the 1 and 2
connectors signify? It looks like this:

<-->
0 1 2 3

Thanks,
Jim

A not to wild guess is Network

Michael,

I know the ports are for network. The thing that was a little confusing
was that "<-->". Are you saying that that's just Sun's labelling for
network ports? We were kind of guessing that because of the position of
the labelling, it might signify that the "1" and "2" ports were somehow
different, e.g., they were compatible with either "normal" or
"crossover" ethernet cables.

Here's a URL that should help. It gives a rear view of a 240.

My "wild" guess is simly that these four are networks ports, all the same.

Sounds strange if Sun would configure for "crossover" ethernet cables
when there are cables for that and today autoconfiguring switches and
maybe even the port is autoconfiguring I don't know but maybe!
