1363.0. "HUBwatch V3.0 doesn't display Network Utilization on DECconcentrator 900MX" by UTRTSC::BEEKMAN (Ton Beekman - NL/MCS - 7838-2345) Wed Aug 31 1994 10:58

	Hello,

	I'm using HUBwatch V3.0 and a DECconcetrator 900MX	
	The FDDI MAC Summary Window has a field with Network Utilization,
	however this field is greyed out. (NA)

	Is there any change that this will be implemented.

	Thanks, 

	Ton.

    The reason this field is greyed out is that your concentrator
    has the MAC-2 chip, not the newer MAC-3 chip.  All concentrators
    built today have the MAC-3 chip.

	obvious question: is there a way to field upgrade to the new
	chipset?

	(I can live without it but it would be nice)

    The MAC chip is not a field replacable item.  It has been done here
    in the lab, but is something you do when you have no other choice.
    
    Since the MAC-3 is a drop-in replacement for the MAC-2 the hardware
    revision number was not bumped.  In hind sight this may have been
    a mistake.  The best way to determine if the concentrator has a
    MAC-3 chip is from the date code.  The the date code is the first
    three digits following the AS in the serial number.  If the date
    code is AS429 there is medium chance you have the MAC-3.  If the
    date code is AS432 or higher you have a MAC-3.
