The ones I got were

Server Technologies Sentry Switched Cabinet Distribution Unit CDU CW-8H2-L30M
Server Technologies Sentry Switched Cabinet Distribution Unit CDU CX-8H2-L30M

The CW is the master, and the CX uses a 6-pin telephone cord to connect to the master.  So 12 switched plugs on two CDU (two 30A circuits) that are controlled from the one web interface.
