| What are your software revs for the DEChub 900 MAM and the
DECbridge 900MX?
Did you power cycle or reset the hub or the bridge at any
point during the LAN Interconnect setup?

| 2768.2 | What other modules are in this HUB? | NETCAD::BATTERSBY | | Mon Sep 18 1995 11:19 | 5 |
| It might also be useful to know if there are any other modules
in this HUB besides the mentioned DECswitch900EF and un-mentioned
DECserver type.

| 2768.3 | Possibly a configuration problem | NETCAD::CARRAFIELLO | | Mon Sep 18 1995 14:46 | 16 |
| The Thinwire connection on a DECbridge 900MX is not a default
connection. At power up all connections default to the front panel
ports. You have to explicitly configure Port 3 to the backplane
Thinwire if you want that connection.
The explanation in .0 sounds like the first 5 ports were configured to
backplane LANs which I interpret to mean matrix channels. If this is
true then Port 3 would have been connected to a matrix channel and not
the backplane Thinwire. The other possibility is that the ports were
only pointed at the backplane via the Hubwatch ligo but not actually
connected to a backplane channel on the configuration screen. Also if
all of the Ethernet LANs were connected together as stated in item 3
then most of the ports would be in the backup state and they wouldn't
pass traffic.

| 2768.4 | In reply...been there seen it done it many times | PTOJJD::DANZAK | Pittsburgher � | Mon Sep 18 1995 15:06 | 26 |
| well...
to reply...
all hub modules were at 4.1 of firmware rev/kit
the hub (from what I recall...) slots are:
Roamabout
token ring 8 port repeater
token thing 2 port repeater
DECconcentrator 500
DECswitch 900MX
DECserver 900TM
DECrepeater 90GM
I did reset the module, remove it from the hub, turned the LIGO types
around to the backplane...watched 'em do spanning tree (indicating that
they were turned around) and when I connected it to the
thinwire....(port 3) it lived for a bit then died....
Any thoughts?
REgards,

| I wonder if the port 3 summary window shows any "interesting" errors?
From your description, it sounds like a possible hardware problem...
Bob, under what circumstances would the port LED go dark?

| 2768.7 | My guess is, there must have been a loop created | NETCAD::BATTERSBY | | Tue Sep 19 1995 17:05 | 12 |
| <----- RE: .5
Mike D. Like Mike Carrafiello said, somehow there must have been a
loop created, and port 3 detected the loop and went into backup.
Also like Mike C. said, port 3 doesn't default to the thinwire on
power-up like the repeaters do. So perhaps connecting the first 5 ports
to backplane channels, and then following this up by attempting to connect
port 3 to the thinwire is what created the loop. I'm not sure of the
exact order that Jon D. is alluding to in his base note when describing
what he did.
Bob
|
| 2768.8 | Not a loop... | PTOJJD::DANZAK | Pittsburgher � | Wed Sep 20 1995 08:00 | 25 |
| NO....wrong....NOT right....
When a loop is created the LED flashes...it doesn't go dead.
AND....i loose connectivity to the terminal server connected on the
LAN.
That is......
I have a 900GM that connects me in slot 8 to the backbone in the
building and management station....
When I take the TERMINAL SERVER in slot 7 off of the thinwire and put
it onto a FLEXlan and then use the decswitch to switch between the
flexlan and thinwire.....the LED on 3 goes DEAD (not blinking doing
spanning tree) and my server looses connectivity to backbone
services....
(one service being reverse-LAT tot he hub management port.....
so.....i KNOW that it's not a loop becuase i loose connectivity to the
THINwire from other flexlans....
duuh...sigh....

| Okay let's start from ground zero -
- check for bent pins on modules and power supplies (don't see how
this could be related but let's not overlook)
- reset MAM and all modules to factory defaults
- A04 on the backplane should have the stiffeners but what slot is
the DECbridge in? Just for kicks try moving it to slot 1,2,3 or 4
- confirm that you're running MAM 4.0.4 and DECswitch 1.5.0
- show us the error log for the MAM and all modules
- try swapping out the DECbridge

| 2768.10 | Same results - stiff hub, update firmware any slot etc... | PTOJJD::DANZAK | Pittsburgher � | Thu Sep 21 1995 13:15 | 329 |
| Did all of the above EXCEPT module swap....no time but will try l8ter
2night......same results....attached is error log:
note that in the MAM error log the power supply junk was me zipping it
on/off during a demo....the repeater (on thinwire) showed no errors...
no pins, reset EVERY module and hub and all were at current firmare
(i.e. 4.0.4 hub 1.5 switch etc...)

| 2768.11 | DB900 looses thinwire connection puzzle resolved... | NETCAD::BATTERSBY | | Fri Oct 13 1995 11:50 | 11 |
| I have resolved this problem. Jon was kind enough to bring this
module with him on his recent visit to LKG.
I tested this module out and found that it failed a test only
run in manufacturing, Test B05 BTW External Loopback Test.
My investigation further found the -9V DC-DC converter to be defective
along with the DP8392 Thinwire chip. This is an external loopback
test that cannot be run in a HUB as it would "disturb" other modules
which may have already established a connection to the HUB backplane
thinwire channel.

| 2768.12 | ESD possibly could have caused this failure.... | NETCAD::BATTERSBY | | Fri Oct 13 1995 11:54 | 7 |
| One other comment, I neglected to mention is that a possible
failure scenario is that perhaps there was some ESD (electrical
static discharge), present on the HUB thinwir channel this module
was plugged into when it first failed, and the ESD zapped the DP8392
and then took out the DC-DC converter.
