3721.0. "Location of Temperature Sensor on HUB900 Chassis" by PRIVAT::OTTO (getting better all the time) Thu Jul 18 1996 13:07

Hello ,

in a previous Note it was mentioned that the Hub900 Chassis itself (no 
modules, just Power supplies) has a temperature Sensor. In Hubwatch 
Environmental View I can also see a Display For the Chassis.

A customer has two Hubs which display a "MAM Yellow Condition" in the 
Display on the Backplane itself, while when looking at those Hubs with 
Hubwatch everything is shown as normal. The customer states that the Hubs 
are "warm", so what the Display shows, is obviously true.
The Firmware of the two Hubs is V4.1.0

The customer has another Hub in a testing Environment and he would like to 
do some heat Tests. To do this, he needs to know where the Temperature 
Sensor for the chassis is located, in order to use a Blower in that  area.

So where is this sensor located anyway ???



Thanks

3721.1Temp sensor locate on MAM module....NETCAD::BATTERSBYDon't use time/words carelesslyThu Jul 18 1996 13:294
    The temp sensor IC is on the MAM module itself. It's an LM34
    lcated next to a row of DRAM chips I believe.

3721.4Please clarify what/why you want this in manual?NETCAD::BATTERSBYDon't use time/words carelesslyThu Jul 18 1996 22:297
    I'm not sure I understand what it is you are suggesting to go
    into the manual. The "MAM Condition Yellow" implies it's the 
    MAM going overtemp, not something else. So you just want a
    piece of text stating the temp sensor that triggers the 
    "MAM Condition Yellow" is on the MAM module?

Hello Bob,
 as I was the asking person for this I thank you very much 
for this exact and quick answer . I don't know why or what should go 
into the manual about the location of the temperature sensor .
Anyway I am happy with Your answer..
Maybe this would be interesting for Field Service..

Thanks

3721.6This is a firmware problem...NBOFS1::JAKOBTue Jul 23 1996 14:1311
    
    
    Hello,
    
    the message of 'MAM in yellow...' is a problem of firmware version
    v4.1.0.
    When you update the firmware to v4.1.1 this error message will not be
    displayed.

3721.8DECconncentrator900-FH and Hubwatch 4.1-xCSC32::B_GOODWINMCI Mission Critical Support TeamTue Jul 23 1996 14:587
Will Hubwatch V4.1-x support the DECconncentrator900-FH? I know it's not listed
in the spd, but the DC900-TH was listed and I thought there were about the same
except for UTP .vs Fiber. My customer still wants to use D-unix and doesn't want
to go to a Microsoft platform.

Thanks,
Brad

Haello Brad,


also I cannot confirm this by having it done or seen myself (I have 
no DEConcentrator900-FH available) this is what I found in the Release Notes
to Hubwatch V4.1 for DEC UNIX


            1 Introduction

               Version 4.1 of HUBwatch for Digital UNIX is the third release
               of the HUBwatch application on Digital UNIX. Version 4.1
               of HUBwatch for Digital UNIX provides all the functions of
               the V4.0 release and adds support for the following network
               modules:

                  DECconcentrator 900FH
                  Digital MultiStack System

               The HUBwatch V4.1 software also recognizes the following
               modules when they are installed in the DEChub 900MS:

                  DECpacketprobe 90 and 900RR
                  RouteAbout Access EW and TW
                  DECswitch 900EE and 900EF contain bridge/routing firmware


Hope this helps...
