    You have to start the Netrider TFTP server (which gets installed along
    with HUBloader).

Thanks for the reply's

	The TFTP server I'm using is the one that comes with hubwatch
AND it seems to be working, I checked before I tried a load (opened the
tftp server window) and it was already loading.

The hubloader regularly gives an update once I start it, in the progress
log it updates every 15secs or is this just telling me its sending and
after 315secs it fails.

hubwatch works fine so I have the link !!!

    I have the same thing happening to me.  However, I'm going from a 4.0
    MAM to a 4.1 MAM upgrade and I'm using HUBwatch 4.1 on my PC.  The
    connection is fine.  I can see the Hub via HUBwatch and HUBloader
    identifies each module in the hub when I select the slot.
    
    Do I have to be plugged into the IP services module on the hub?  If so,
    what about a 20 hub network - or 5 hubs for that matter!  I don't think
    going to each hub to plug into the IP services module sounds the least
    bit attractive.

I don't know if this is the same problem. But, I had something like your problem
loading from my pc. *** Beware of the Digital PCBU PCMCIA ethernet card. It is
garbage. *** You can identify this card by:

       Remove your PCMCIA ETHERNET card from your Laptop.  The cards that
       are generating problems have a yellow and purple background behind
       a black digital logo in the upper left hand corner.  Below this is
       a black stripe with the words "Ethernet Adapter" and there is no
       model number or part number on the back.


After trying to upgrade my mam, it would fail. When connected to the console of
the dh900 and doing option 3 "Show Current Settings" for "Status of Last
Downline Upgrade" it showed "CRC Error" or something of that nature.


More info on the card follows:

The PCBU is working on getting a process in place to take care of the
problem...They should have a solution soon and I will send that
out as soon as I get it.

Subj:	ETHERNET CARD TO BE REPLACED

Based on PCBU Engineering's continual testing of PCMCIA Cards, we have un-
covered a reliability problem with the Digital-branded Ethernet card.  We
have placed the following cards on SHIP HOLD:

	FR-PCP78-AD (combo 10baseT/10base2)
	FR-PCP78-AC (10baseT)

The typical symptoms on the combo card are intermittent bursts of CRC's, high
collision rates, and misaligned frames, eventually resulting in a crashed
network.  Although the problems were only detected on 10base2, to be conser-
vative we placed on hold the 10baseT card as well.  Retesting of that card
will be completed next week. 

Please do not confuse this product with the DEPCM-A* product offered by the 
Network Products BU.

It is the the intention of the PCBU to offer to replace defective cards with
the customer's choice of a card from a specified set of other cards that pass
our full compatibility and reliability test suite. 

At this point, we do not have a process in place.  We expect to announce a 
simple swap process in the very near future.

Please understand that we fully realize how frustrating this entire scenario
has been with these cards and are doing everything possible to rectify this
situation as quickly as possible.

	It probably wasn't already loading if you checked it BEFORE...
    	probably the BOOTP request counter was ticking.
    
    	You need to see the TFTP request & response counters _both_ increment
    	by 1 to know that the MAM requested the image. Also, in the lower
    	window the "transfer cnt" number should be constantly increasing.

    	The Hubload update is merely polling the MAM to see what the current
    	status of the MAM is. You can't tell from the status how many 
    	retries are happening for instance, or even if the MAM has seen any 
    	packets at all yet - you just know that it is trying.

    	Check for the things in my previous reply -.1 .  Also, make sure the 
        IP address and host name are correct for your PC in the
        \netrider\load\loader.ini file.

    	Well, you need connectivity to your hub. If you manage your hub 
        in-band then you need connectivity to the IP services module. Just like 
    	for Hubwatch. No different.

just back from site..

I had a copy of mam 3.1 so I tried that just to see as this 
particular hub was running version 2.*. 

This worked fine so I then tried v 4.1 again and got the failure???

when I look at the two images the V4 is about twice as big as V3.

I also checked the loader counts as per previous reply and they
do increase ok

still confused but maybe a reinstall of the "very latest" Version
of the software may fix this.

    In Reply to note .5.  I have the DEPCM-A* card offered by NPBU and not
    the inferior PCBU card.  All my *.ini files have the correct IP host
    address.  That includes the netrider\load\loader.ini file.  As far as
    connecting in-band, I hope I can access the IP services module (DETMM)
    thru an external port off a DECswitch 900EF and across the backplane of
    the DEChub 900.  This same config worked when I loaded 4.0 from 3.1!

    Well,  I directly connected the PC to the 900TM and it worked!  It
    should have worked going the through the 900EF and the backplane
    segments.  I don't think (feel) I should have needed to increase the
    time-out value on the HUBloader.
    
    Anyway, it finally worked...
