I was just about to scrapp 4 module when 2 more came in from the field.
Up till now we received 6 modules (lynx backplanes) with the same
problem.
The problem is not eisa related. PCI also showes some problems. Also
it is not ev5 related. With an ev4 you have to look very closely to
see the the problems. Most times it looks ok. For example the latest
2 module seem to work fine in vms windows with an ev4. But with an
ev5 the vga screen frezes up (no keyboard or mouse action) 2-3 minutes
after login.
You can login at the serial port an run some tests after vga freezed
up.
Can someone explane this trange behaviour ???
PS: I used different memory, cpu and graphics card with same result.
I also tried firmware V47_GLUPDATE

| 2451.5 | Help.. Same symtoms after 2100A Upgrade.. | CGOWGS::GIBB | John Gibb Canadian Multi Vendor Support | Wed Feb 12 1997 01:45 | 25 |
| Howdy,
Glad to see other engineers seeing this problem. We just did a 2100a
upgrade with no problems except for video problems outlined in .1. Even
unix is booted, xwindows doesn't come up. We have a Qvision card and we
are going to try a s3 trio to see if this has any effect on the
problem.
The customer mentioned that they recieved a new 2100a with a ev4 275
cpu and had allot of problems with the video. The problem has
disappeared but even once and awhile the system crashes when they use
the video console. Not sure if this is related.
The above config is a ev4 275 cpu..
Any thoughts or ideas would be appreciated..
BTW.. we have tried both firmware from V3.6 and V3.8 cd's and also ECU
V1.9 and V1.10..
Thanks
John Gibb

| I have contacted Kanata MFG a will send them some sample modules
to put through their stg1 and 2 process.
Stay tuned..it may take a while..

| 2451.7 | Another upgrade with video problems | SCASS1::TURNERG | | Wed Feb 19 1997 16:04 | 8 |
| Well add another upgrade to this list, I just did a 2100 5/250 to a
2100a 5/250 the system and it had a ATI MACH 64 ISA card for video
when we ran arc we would get missing character and horizontal dashes
on the screen. When we would boot up VMS 7.1 it takes forever to log
on and the screen is srambled. I've tried a Q-vision eisa card and a
Number 9 Trio64/Trio32 pci video card all with similiar. Is this a
backplane problem are these cards not supported on 2100A. What card
should they be using.

| 2451.8 | 2 more backplanes | JGO::POLFLIET | | Thu Feb 20 1997 11:40 | 60 |
| Today we received 3 field return modules of wich 2 showed the screen
problems with an EV5 cpu (5/250).
The first one when moving the window around in vms leaves the window
outlines on the screen, so your screen fills up with horizontale and
vertical lines.
On the second one the screen (vms) freezes up a few minutes after
login. Don't know if this is of any use but looking in
DECW$SERVER_0_ERROR.LOG I saw the following (used the serial port, this
still works):

| 2451.9 | Replacing backplane fixed video problem | SCASS1::TURNERG | | Fri Feb 28 1997 14:13 | 5 |
| I just replaced a 54-24129-01 yesterday because of video problem.
The Rev of the board is a E01 serial number is ka648sydsy. I put
the new backplane in and video worked fine. One thing I noticed
that was when this when this backplane was installed the board was
in EV4 mode out of the box.

| 2451.10 | power?? | JGO::POLFLIET | | Wed May 28 1997 11:38 | 11 |

Not sure about this but it looks like that some backplanes are
sensetive to a bad +5V, measured on the backplane.
If the +5V is more than +5.15V (approx) you will see the symptomes as
described in the previous replies.
So before replacing the backplane check your +5V measured on the backplane.
If I am wright you will have to decide wether to replace the backplane
or to replace the power.
Martin.
