Motorola ACE3600 RTU - Leds Behavior

Expansion Module
17-11
Scenario Trigger Action
RAM Test During startup, press PB1. A detailed memory test of SDRAM and
SRAM plug-in is performed.
- At the beginning of the RAM test, the
four indicator LEDs (see LEDs Location in
Table 17-2) will blink three times. During
the RAM test, the LEDs may blink or be
lit.
If the RAM test succeeds, the four LEDs
will blink three times and turn off and the
restart sequence will continue.
If the RAM test fails, the RTU will freeze
(restart sequence stops), the PWR LED
will blink and the four LEDs will blink
seven times. The failure error code will
then be displayed on the LEDs, in binary
code, as described in Table 17-3.
- To exit/abort the RAM test in the middle,
restart the RTU using the On/Off switch
on the front panel.
LEDs Behavior
The table below describes the behavior of the LEDs on the expansion module.
