| I assume that the DR90FS (DEFMI) is a fully implemented 900-series
agent (though in a half-height module) and is capable of performing the
media access for the MAM?
I have a customer upgrading a DEChub90 (with lots of old 90L, and 90L+
in a 16-slot hub, with a bridge module to the site backbone.

The first Hub is going to be upgraded to a 900 series backplane,
and all of the modules moved to the 900 backplane. But at that time, I
don't know how to get the "network" into that hub. There is only a
ThinWire cable from the second hub providing LAN access, and a peice of
UTP running for the management bus. I would like to remove the DA90
module, and place it somewhere else on the network. Then, I would use
the spare slot, and have the customer purchase a DR90FS (DEFMI-M) which
is the least expensive way to connect this hub to the LAN. I would
come off of the 90FS with a transceiver cable to a Thinwire MAU.
I assume that this module would allow the new 900 series backplane to be
managed, and the customer could watch the status of the power supplies,
and gradually replace the 90 modules as funding allows, with new DS900M
servers and other neat stuff.
The right hub (with the DB90FL connection to the backbone) would remain
a 90 series for now, and would later be converted to a 900. If the
90FS cannot act as the media port for the MAM, then is there another
inexpensive way to provide management for the 900 hub, populated only
with dumb terminal servers and about $1500 dollars to spare.
Thanks,
JR
