Desktop Board Features
On-board Power Indicator LEDs
CAUTION
If the AC power has been switched off and the + 5 V standby power indicator is still lit,
disconnect the power cord before installing or removing any devices connected to the
board. Failure to do so could damage the board and any attached devices.
CAUTION
When connected to AC power, the memory slots on the board will be powered and in
use. A red LED (Figure 3, B), located near the memory slots, will be lit if the memory
slots are powered.
Installing or removing memory from the board while the memory slots are powered
may result in damage to both memory and board.
Before installing or removing memory, disconnect the system from AC power and wait
for the LED to go off before proceeding.
The desktop board has two on-board power indicators: a + 5 V standby power
indicator (green LED) and a memory power indicator (red LED) shown in Figure 3. The
+ 5 V standby power indicator (Figure 3, A) is lit when there is standby power still
present on the board even when the computer appears to be off. The memory power
indicator (Figure 3, B) is lit when there is power to the memory slots.
