Ethernet ready Compact Outdoor SSPAs can be identified by either serial number or label.
Compact Outdoor SSPAs with serial numbers greater than 300,000 are Ethernet ready. Also
Ethernet ready units have the following label affixed adjacent to the M&C connector, J4.
Ethernet ready units can be configured for either RS-232, RS-485, or Ethernet communica-
tions. The units cannot be used with multiple communication protocols simultaneously. The
