Hi gang -
Thanks to John Clifton, V.S. Glukhov, Sean O'Connell (from my alma mater,
Duke University!), John Joehnk, and Seth Hall.
There wasn't unanimous reponse on whether or not I'd need a DE500-BB or
a DE500-BA - people had had success with both, and I'm not sure of the
difference.
V.S. Glukhov sent a detailed response that sums this up pretty well:
"> 1) Who should I order this card from and how much should I expect it to
cost?
Any DECPAQ reseller will do the job. I use SoftNet solutions
(marlene_at_softnets.com).
About $100.
> 2) What steps should I take to install this new card? Including...
Shut down the system. Open the hood. Install the card.
> 3) How do I disable the old 10mbit card?
On these systems the old card is integrated into scsi/io card,
if I am not mistaken. You should just tell the system to use
tu1 instead of tu0. See below:
> 4) How do I make sure that my system recognizes & uses the new card (at
> full speed) and that my existing network configurations "use" this new card?
There are now two ethernet devices in your system. It the console level
they are recognized as ewa... and ewb... The latter is probably your new
card.
Get to the console prompt ">>>" and set the ewb mode to FastFD or Fast,
depending on your needs - Fast Full Duplex (when connected to a 100M switch),
or Fast (when connected to 100M hub). You can figure out which variable to
set if you "show ew*" (I don't remember this off the top of my head.
But I do remember the _method_ and general direction. :)
[Note: John Clifton's comment for this was:
"Just remember to set the card speed up at the
console prompt (P0>>>) by using set 'ewb0_mode fast'."]
Boot the system and check the boot record using "uerf -R" or "dia -R",
whichever way you prefer. You should see something like:
tu0: DEC TULIP (10Mbps) Ethernet
_Interface, hardware address:
_00-00-F8-22-XX-XX
tu0: console mode: selecting 10BaseT
_(UTP) port: half duplex
....( that's your old card)
tu1: DECchip 21140: Revision: 1.2
tu1 at pci0 slot 12
tu1: DEC TULIP (10/100) Ethernet
_Interface, hardware address:
_00-00-F8-04-YY-YY
tu1: console mode: selecting
100BaseTX
_(UTP) port: full duplex
.... (your new card)
Now it's time to tell your system to use tu1 instead of tu0. You can use
either graphical System Admin tool: write down all network parameters
associated with tu0 and transfer them to tu1, then disable tu0.
Or use you favorite editor to edit /etc/rc.config:
HOSTNAME="hostname.uu.com"
NUM_NETCONFIG="1"
MAX_NETDEVS="24"
NETDEV_0="tu1" #<----- HERE
IFCONFIG_0="111.222.222.111 netmask 255.255.255.0"
You can disable the old card and enable the new card without restarting the
system using "ifconfig" (man ifconfig), but to make your changes permanent
you should change /etc/rc.config.
> 5) And anything else I might need to know to get this done...
Some switches can not wholeheartedly accept TULIP cards at their full
duplex speed. These switches' ports has to be manually set up to
fast full duplex. I would suggest you use the following sequence:
1) Do not set up the card's speed at the console level and let the
card and the switch negotiate the speed.
2) If no traffic is coming through or the switch shows the error light,
set the card to Fast at the console level,
3) If (still no traffic || error) then set FastFD at the console
4) If (still no traffic || error) throw away either the card or the switch."

Personally, option #4 sounds like a good one with a lot of computer
equipment!!!
Sincerely,
Colin
