| 3072.1 | No FRU's make up the HUB other than the MAM module.. | NETCAD::BATTERSBY | | Fri Dec 15 1995 12:50 | 11 |
| I don't believe that other than the MAM module, that there were
intended to be any other FRU's (field replaceble units), that
make up the components of the HUB. Thus, if there is a problem
with an internal cable, or internal modules, or other internal
workings of the HUB, that it is returned or exchanged for another
one. That being the case I believe, one won't find any documents
for field use on reparing the HUB inner workings. These types of
repairs were intended to be done in a manufacturing plant that
builds the product.

| 3072.2 | some german mistake | BERFS4::NORD | | Fri Dec 15 1995 12:52 | 11 |

Another "Hi you",
I've to learn english or to look at my monitor, 'cause there are some
mistakes, I've done:
"ther" meens "there", and "solf" meens "solve", sorry about but in
Germany it's 07:00 p.m. and I'm working since 07:00 a.m. (like you do!)
Thanks

What I meant here is that the whole hub is returned if it is determined
that it is a component other than the MAM module. EVen with the MAM
module, I'm not certain if this is an "official" FRU part.

| 3072.4 | first answer !!! | BERFS4::NORD | | Fri Dec 15 1995 13:05 | 16 |

Thanks Bob for your answer,
but I think we have to replace one or another module and I don't know
what I've to order, 'cause I'm not shure what to change. The best thing
I know, is a exploding drawing, to know what is in the backplane and
what this module is doing.
I opened the the backside of the DH900 and I found some things, where
is no documentation and where is nobody, who can help me, but I've to
replace the rigth thing.
Many thanks for your answer

| 3072.5 | Just the MAM, man | PTOJJD::DANZAK | Pittsburgher � | Mon Dec 18 1995 21:29 | 19 |
| I think what bob is trying to say is....
Other than the module at the top of the hub behind the plastic case
(the one with the LCD display) there is NOTHING to take apart or should
be taken apart in the field. (i.e. you should NEVER have to take off
the hub back etc. except to uprev an A01 hub with stiffeners)
You just pop off the front plastic, take off the two screws at the top,
unplug the bottom connectors and slip in the new MAM.
The backplane simply has some capacitors and resistors (all triple
redundant) and if it failes, you just get a new one.
(It's lots cheaper doing it that way and causes us field types to work
less hours....!)
(grin)
