Please provide the serial # and HW rev for the DEChub 900 backplane.

| Please also check your power consumption. Check error log.

| 2896.3 | Speculative guess... | NETCAD::BATTERSBY | | Mon Oct 23 1995 11:04 | 5 |
| Speculation on my part, but it sounds like an old HUB in need
of stiffeners. Sounds like some kind of intermittent backplane
connectivity.

| 2896.4 | Hardware rev and S/W rev | CHEFS::RUMMING_K | | Mon Oct 23 1995 14:26 | 11 |
| Herewith the rev level of the Hub reported via the serial port:
The serial number is obscured by equipment mounted in the Cabinet above
the Hub.
Hardware rev f
RO=V1.1.6
SW=4.0.4
Any ideas gratefully received!
Keith.

The info you've provided is related to the MAM and has no relationship
to the Hardware. As Bob said, the problem sounds like a stiffener
issue so you need to check the HW rev. The mounting bracket usually
obscures the serial # but the HW rev should be visible.
How long has this DEChub 900 been in service?

| Bill,
The DEChub is (hopefully) new. We've had it since August this year, and
I guess the DECgroup in the US ( VIIS in SHR) built the cab in July.
I will find the hardware rev i'll dismantle the cab! What rev is good?
regards,
Keith

| 2896.7 | Serial Number of Hub | CHEFS::RUMMING_K | | Tue Oct 24 1995 07:10 | 2 |

serial number of the Hub is AS51102692

| 2896.8 | Swap positions of concentrator & switches & what happens... | NETCAD::BATTERSBY | | Tue Oct 24 1995 09:47 | 11 |
| Well that serial number rules out the need for the stiffeners
ECO to fix the pin wipe problem seen on older hubs. The stiffeners
fix was implemented on DMHUB-MBs with revision of A04 and higher, and
DMHUB-MAs with revision of A03 and Higher. A AS5XXXXXXX serial number
should have this ECO.
If Keith is willing to experiment, it might be useful to see what
happens if the Concentrator 900MX is installed in slot 7 or 8 and
the PEswitches installed in the lower numbered slots. I'd also
be curious to know if any errors are written to the PEswitch error log.

| There is a new pin wipe fix that should be installed on this DMHUB.
The problem affects FDDI connected modules in slots 7&8.
DMHUB's coming out of manufacturing have the fix but the official fix
kit for existing DMHUBs is not available as yet.
If you send me (NPSS::WADE) your mailing address I'll send you the kit and
installation instructions so you can get the customer up and running.

Bill,
Can you tell me more about this problem ... I have large FDDI
customers who puts 6-7 FDDI devices per hub ... I have'nt run into this
problem yet but would like to better understand it.

Within the next couple of weeks a blitz will be sent out describing the
problem and containing the part number for a "DEChub 900 MultiSwitch Pin
Wipe Upgrade Kit".
