Base Cabinet

The DK424 Base Cabinet provides two designated slots for the RCTU processor and six universal
slots for station, line, and feature PCBs. It provides six connectors for expanding the system to a
maximum of six Expansion Cabinets. It comes with a Motherboard Jumper Unit (MBJU) installed
between the R11 and RCTU slot on the front side of the backplane motherboard. The MBJU is
removed only when RCTUE/F is installed. MBJU is installed for all other DK Release 1~4 RCTU
processor PCBs.
