1121.0. "Always hot Swapped ????" by CLPR01::PEYRACHE (Jean-Yves Peyrache Country Support Group France) Wed Jun 15 1994 13:26

 hi,

  in Release notes on Hubmanager V3.0 a items said

 " Do not remove a DECbridge900Mx or a DECconcentrator900MX from the DEChub when
   power to the DEChub is off"

 can anybody explain this particularity ??

 as only for the re-calculation of power by Hubmanager of for others purposes ??
 if you bypass this restrictions could you damage somes pieces of Hub ??

    Quote:
    
    "The short answer is that if you made some backplane
    connections from other modules to a concentrator (or bridge)
    through the HUBwatch LAN Interconnect window, then power down the hub
    and remove the module, when hub power is restored the hub manager
    cannot yet deal with how to resolve the connections which no longer
    exist to the now-removed module (i.e. the matrix is still programmed 
    as if the concentrator were still in its slot). Known problem,
    that's why it's in the release notes."
