(1) System status LEDs

Check that the POWER of the system status LEDs is lit immediately after the power is activated. If it is not lit, shut off the

emulator and check the power supply for the emulator is properly connected.

(2) LED for checking the connections of the target status cables

Check that the LED for checking the connections of the target status cables is lit immediately after the power is activated. If it

is not lit, shut off the emulator and check the target status cables are properly connected.

However, even under normal operating conditions, when the power supply voltage is less than 3.3 V, the GOOD LED will dim

or will not turn on.

(3) Target status LEDs

Target status LEDs light as shown in Figure 2.11. For about 2 seconds after power is turned on, all the target status LEDs light.

After that, make sure the target status LEDs light up normally.

When the target status LEDs do not display as shown in Figure 2.11, refer to “5. Troubleshooting” (page

73).
