5 Power and reset buttons
The power and reset buttons are present on the front panel of the LX2160ARDB chassis (see Figure 1). Both power and reset
buttons are push buttons. The table below describes the power and reset buttons.
Table 5. Power and reset buttons
Identifier Label Function Description
SW5 PWR Power cycle Pressing SW5 turns the power ON or OFF
SW7 RST System reset Pressing SW7 resets the system, including the device and all the
attached peripherals
You cannot switch off the board completely when the SW_AUTO_ON switch (SW4[2]) is set to ON/1. In this mode, pressing the
power switch turns the power off briefly, then it immediately turns back on. To turn off power, set the SW_AUTO_ON switch to
OFF/0 or disconnect the AC power.
To avoid any damage to SDHC1 port pins due to a silicon erratum, follow these recommendations:
•Always use the power button on the front panel to power down the system. Do not power down the system by unplugging
the power adapter.
• Before removing AC power to power cycle the system:
— Insert an SDHC card in the SDHC card slot
— Allow Linux to boot and configure EVDD to 1.8 V

8 DIP switches
The LX2160ARDB provides dual inline package (DIP) switches to allow easy configuration of the system for the most popular
board options. These switches are stored in BRDCFG and DUTCFG registers by CPLD before being used, allowing software
(either local or remote) to reconfigure the system as needed.
The table below explains the DIP switches available in the LX2160ARDB. For each DIP switch:
•If the switch is up (on), the value is 1
• If the switch is down (off), the value is 0
