    This is not directly related with management but I don't know any other
    conference that could answer.
    
    One of our network resellers saw that some ports of a DECrepeater 90FL
    was not functioning. And he decided to measure the output level of the
    f/o ports. The transmit level came out to be -19 dB  in the healthy
    ports and -34 dB in the malfunctioning ports. 
    
    The specific unit in question was not installed for about one year
    since it was purchased. I do not know in what kind of environment it
    was stocked (ie., dust, dirt...) but I think this may be due to a
    mechanical problem. Any comments on this? As the warranty preiod has
    expired the reseller wants to repair this unit with the minimum cost.

| 3192.1 | Were dust boots in place when reseller opened box? | NETCAD::BATTERSBY | Mon Jan 22 1996 11:37 | 5 | |
|     Do you recall asking the reseller if there were dust boots on the
    fiber ports when they first ascertained that some of the fiber
    ports were not functioning?

|     Yes. This is the most probable thing, and was checked from outside of
    the box. However I do not know the inside of the box. That is, how the
    light source is coupled physically to the port and if there is a chance
    of dust covering the light source. Also a physical shock to the port
    might have loosen this coupling. I seems that there isn't much to do
    except a good eye inspection.
