•
At the SC-ADT 8-port or 16-port device, one Ethernet interface connector is provided at the
lower RJ48C connector located on the shelf rear panel (J33-J48).
•
For the SC-ADT 32-port device, one ethernet connector is located at the base card rear panel
(J33-J48).
The Ethernet port provides 10/100BASE-T Ethernet connectivity and require RJ45-to-RJ45
straight-thru or crossover cables (GDC S-078H010-XXX or S-078H011-XXX).
The table below describes Ethernet port pinouts. Note that the Ethernet port can be used as a logical
uplink to SpectraComm Ethernet Switches, SpectraComm IP cards or other hub/bridge devices.
Note
Reserved for future use on the SC-ADT 32-port device are two additional Ethernet connectors at the
Expansion card rear panel (J17-J32 and J33-J48) and their associated front panel LEDs (E2 and E3).
