Why is there no serial cable included with my new Smart-UPS SMT750 or SMT1500RM2U?


Serial cables are no longer included with Smart-UPS SMT750, SMT750US, SMT1500RM2U, or SMT1500RMUS units.

Product Line:



SMT750 and SMT750US, Serial numbers beginning "3S1528" or later (IE: 3S1528XXXXXX, 3S1529XXXXXX, 3S1530XXXXX etc..)
SMT1500RM2U and SMT1500RMUS, Serial numbers beginning "AS1610" or later (IE: AS1610XXXXXX, AS1611XXXXXX, AS1612XXXXX etc..)


Due to the continued decline and elimination of serial communication ports in server manufacturing and in an effort to minimize e-waste, APC™ by Schneider Electric will no longer be providing the RJ-45 to serial communication cable with the Smart-UPS™ SMT750, SMT750US, SMT1500RM2U, or SMT1500RMUS models.   


For a limited time this serial cable will be made available free of charge by registering at
You will need your exact model and serial number available when registering. You can find this information on the back of the UPS, a sticker on the corner of the shipping box, or via the "About" menu on the LCD screen.
