HUB Manager Assisted Load:

        The following DEChub 900 modules are capable of loading 
        firmware via the DEChub Manager.  This requires that an 
        IP address be set on the DEChub Manager and one of the 
        modules act as the HUB IP Server.

          DECconcentrator 900MX
          DECconcentrator 900TH
          DECconcentrator 9900FH
          DECswitch 900EE
          DECswitch 900EF
          PEswitch 900TX

        Loading via the DEChub Manager eliminates the requirement 
        of setting an IP address on the module itself but the load
        is done via the DEChub internal management bus which is much 
        slower than a direct LAN connection to the module.
