I don't think it is a KA655 then, there is no on-board ethernet. The KA650 
and KA655 neither have onboard eithernet whereas the KA640 and KA670 at 
least both do (I don't know about the KA660). I suspect what you have is 
the KA640.

Also it is a small point but the BA215 is a horizontally mounted rack mount 
enclosure, about 14" high and 26" deep. You may be thinking of the BA213 
which came in the stand up pedestal and was sometimes mounted directly into 
as rack (usually a H9644) with some RA drives.

The KA655 was the last upgrade for the BA123 Microvaxen according to my DEC 
options catalog before they chucked out that chassis and started supporting 
only the BA2xx series. Since these machines had either a DEQNA or DELQA in 
them there was no need for on board peripherals.

The KA640 and 670 also both have on board DSSI (640 has one, the 670 has two)
