964.0. "10base-T Ethernet on Power Mac?" by 19584::GOLDSTEIN (Andy Goldstein, VMS Development) Fri Jun 06 1997 10:22

This oughta be real basic, but something doesn't want to fly...

I'm trying to get a DEClaser 5100 hooked up to my 7200/90 via 10base-T ethernet.
Real simple - nothing else. Do I need a hub for this configuration, or should a
crossover cable between the Mac and the printer work? I've tried the crossover
cable, and when I try to switch Appletalk to the ethernet port, it thinks for a
few seconds and then reports an error from the ethernet adaptor (suggesting that
the network may be wired incorrectly).

I've checked out the cable and I'm reasonably sure that it's correct. I've been
using the printer for a long time through the printer port. The ethernet board
in the printer is new; I'm using the on board ethernet in the MAC, which has
never been used before. (OK, so I've got 2 variables right there.)

Software: MACos 7.5.5 w/ interrupt extension. "Bultin Ethernet" and "Ethertalk
Phase 2" extensions are present.

964.1If 5100 has Ethernet, use a 5 port hub; otherwise stick with LocalTalk6214::WATSONN1GNB, DTN 225-4898, 293-5922Fri Jun 06 1997 10:3521
    I've heard of someone getting a 10baseT network going with just a
    printer and the CPU, but strongly recommend a small hub.  You can get a
    5 port hub for about $80 and an 8 port hub for about $120-$130.  I'm
    not sure if the 5100 has a built-in Ethernet interface or not, but, if
    it doesn't you can get an Ethernet to LocalTalk bridge (1 Ethernet to 2
    LocalTalk nodes for $220 or so; or 1 Ethernet to 8 LocalTalk nodes for
    $300).
    
    If all you are doing is just connecting the Mac CPU to a LocalTalk-only
    printer, you won't gain that much in speed if you use Ethernet.  But,
    if you plan to connect more Macs (such as a PowerBook) together to
    transfer files and share the printer, Ethernet is the best way to go. 
    File transfers are many times faster with Ethernet.
    
    I use 2 hubs and have 4 Macs connected and 1 DEClaser 1152 printer
    connected via Ethernet.  The 1152 requires the bridge I described. 
    Everything works like a champ.  Doing network disk backups is probably
    10x faster than with LocalTalk only.  Printing to the 1152 from the
    Macs around the house works great.
