Figure 6 GPIO Special Functions Jumpers (Example Configuration)

The GPIOs are accessed via header JP3 as described in the next section. You can set and read the

GPIO state, and set Email alerts and SNMP traps based on the GPIO state as described in Chapter 6 of

this manual.

26-Pin I/O Header

The I/O Header, located at JP3, is a 26-pin interface for connecting to the SX-560 GPIO and SPI

interfaces. It also provides a direct way of connecting to the SX-560 console interface using 3.3V logic

levels rather than the DB-9 RS-232 connector.

The GPIOs, located on JP3, can be used for controlling or monitoring OEM functions. External pull-ups

are recommended for customization.
