1.1 DPCS Replacement
For replacement of DPCS, replace the transmission and power supply modules, and add a fan unit. Install
VETHX1 to the slot 11 or 13 (when the station is redundant) of the VMCUX1 chassis. The other control
cards of DPCS can still be used. However, we recommend to perform an overhaul such as replacement of
parts whose life is expired.
