355.0. "DAS UPGRADE" by PEACHS::SCHULTZ (Peripheral Visionary...) Tue Oct 01 1991 17:30

    
    I need information on upgrading a DECBridge 600 (Triple Ethernet, No
    FDDI) to a DAS MM configuration. According to sales update, all that is
    required is the DAS access module (DEFEB-UP). Is this true, or do I
    also need other hardware.

355.1Looks that wayJUMP4::JOYHappy at lastTue Oct 01 1991 18:106
    According to the NaC Buyer's Guide that's all you need. I would have
    guessed that you also would need an Applications Processor board
    upgrade as well, but apparently not.

    Thats what I thought also, but I guess the AP2 module is already
    included in the 600 bridge.

    As you've surmised, you won't need to order an AP2, as it's already
    there. However, you WILL need to order 1 multimode loopback
    (12-32005-01). The -UP has one, but since the DAS module has two MIC
    receptacles, you need two loopbacks. (Most -UP upgrades were forecast
    to come from customers with the SAS module; that's why two loopbacks
    weren't included in the kit.)
            
    Also, note that these upgrades are not customer installable. Unless
    your customer has technically trained people who are familiar with the
    procedures and equipment used for handling static-sensitive devices,
    I'd STRONGLY recommend that Digital installation be included in this
    upgrade. 
    
355.4Marketing boo booPEACHS::SCHULTZPeripheral Visionary...Wed Oct 02 1991 23:2011
    
    I be doing the installation, and I have oodles of loopbacks since I
    already have 6 concentrators and 2 decbridge 500's.
    
    This poses another marketing issue. The 620 bridge has a list price of
    $34,000 dollars, but I can "Create the same thing" by purchasing an 600
    bridge for $21,000 and adding the upgrade #2 for $7600 which gives me a
    620 bridge at a list cost of $28600. I'll take a savings of $5400
    dollars any day, so will our customers.

Do we have an answer for this yet?

355.6loopback connectors, their use?VAXRIO::ROLFVaporware Design SpecialistTue Oct 29 1991 07:2613
    I am just updating myself with this notefile and came across mention of
    "loopbacks" in an earlier reply to this topic. 
    
    Are these loopbacks strictly for testing or do they have to be in place
    on any unused port for normal operation?
    
    Sorry, we don't have any FDDI equipment in the country yet. I'm just
    trying to learn!
    
    Thanks
