Trouble configuring ether1 interface on IRX-211 (fwd)

Please direct all replies to me. I will summarize.

I'm having trouble configuring a SunOS 4.1.4 machine to talk to
ether1. I think the problem is with the IRX, but I'm having a
difficult time diagnosing.

Here's the hardware configuration:

ether1 has two dip switches -- first one down, the second one up.
This should correspond to AUI. I have working, terminated coax
plugged into the AUI port of ether1 and I have a working 10Base2
transceiver attached to a SPARC 1 plugged into the other end.
This all came from another working thinnet, and if plug all these
pieces back into the working thinnet and reconfigure, they work.
I don't think it's a hardware problem with my hardware.

ether0 has a similar setup, and appears to be working.

Here's the router software configuration:

The IRX is routing for a Class C. I've subnetted the Class C using
255.255.255.128 -- not strictly the best choice, but it appears to
work somewhat -- I have several working pieces of equipment hooked
up off the ether0 interface talking just fine and dandy.

Command> show ether0
Ethernet Status: IP - Enabled IPX - Disabled

Here's the software configuration of the SPARC 1:

SunOS 4.1.4, no patches -- virgin load, new machine. I'm networking
the machine with the following commands:

ifconfig le0 205.149.139.222 netmask ffffff80 broadcast 205.149.139.255
route add default 205.149.139.129 1

I'm thinking that, by all rights, I _should_ be able to see the router
at this point. But I can't ping it, and "show arp ether1" on the IRX
doesn't show my Sun's ethernet address or anything useful like that.
The red light that corresponds to ether1 flickers once in a blue moon,
but that's about it. "show netstat" says:

Name Ipkts Ierrs Opkts Oerrs Collis Resets Queue
ether0 84721 0 108516 0 10 0 0
ether1 0 0 109 0 0 0 0
ptp1 108248 0 84696 0 0 0 0

I'm stumped. Is there something else I can do for diagnostics?
