Re: Power System vs. The Hub -- MIDRANGE-L

I must admit that I just took the easy way out and moved on to the next
square. The IBM hardware tech was quite clear with me that the ethernet
card in the new 8203-E4A was not compatible with old style hubs. The hub
I was using is 10 years old.

Rich, did you try to tweak your line description to half on duplex to see if
it would have worked.

Charles,

I must admit that I thought there would be no difference between a hub
and
a switch, but when I plunked down $30 for an inexpensive 5 port switch at
the local Radio Shack and plugged it in, then the network connection came
right up. The IBM hardware guy told me that the older hub that I was
using was probably just not fast enough for the new ethernet card.

Rich,

I'm not a network guy...but that seems like a very strange requirement to
me....

Did they give you any reason? The only thing I can think of would be
that the Ethernet card is designed only for full-duplex opertaions
which a hub would not support and a switch would.

Otherwise, I don't know how there would be any difference from the
card's perspective between a switch and a hub.

Just installing my first Power i and I've run into a snag. I am
installing a Power 6 8203-E4A but the ethernet line will not vary on.
IBM
support is recommending that I replace the hubs that run the office
network with switches because the ethernet card in the Power 6 is not
compatible with a connection to a hub. The hub I'm using is a 10/100
dual
speed Office Connect from 3 Com and has been in use here for about 10
years. Our trusty old i5 520 running V5R3 gets along with it just fine.

Has anyone had any experience with getting the Power 6 to work in an all
hub environment? This is pretty foreign to me. I don't want to lay out
money for a new office network topology if I don't have to.
