The 9-pin male connector J8 Link Port is used to link a SSPA with other units in a
redundant system in order to pass online/standby status information between them.
Leave unconnected unless specified otherwise. See
Section 4.1.4
and
Section 5.5
.
2.1.2.11 Ethernet Port (J9) [RJ45]
This is a RJ45 connector with integrated magnetics and LEDs. This port becomes the
primary remote control interface when the Interface is selected to “IPNet” as described
in
Section 7.8
. This feature allows the user to connect the unit to a 10/100 Base-T net-
work and have full-featured M&C functions through a web interface. See
Table 2-4
.
Note
: IP address, Gateway address, Subnet mask, IP port and IP Lock
address need to be properly selected prior to first use (see
Appendix A
).
LED lamps on the connector indicate network status. A steady Green light indicates a
valid Ethernet link; a flashing Yellow LED indicates data transfer activity (on either the
Transmit and Receive paths).
