I don't know, but the predecessor was also 100.

the new one is the USW-ULTRA-210W 7-port switch, it replaces the old one and costs 194.
there is an identical 5 or 6 port wall-mountable switch with a plastic adapter but it's probably too old to be found. the USW-LITE-8-POE is perfect except for the mains adapter, which is too bulky for my taste.
