The following illustration shows the LEDs on a dc power supply.
v
Ethernet activity LEDs:
When these LEDs are lit, they indicate that the server is
transmitting to or receiving signals from the Ethernet LAN that is connected to
the Ethernet port.
v
Ethernet link LEDs:
When these LEDs are lit, they indicate that there is an
active link connection on the 10BASE-T, 100BASE-TX, or 1000BASE-TX
interface for the Ethernet port.
v
AC power LED:
Each hot-swap ac power supply has an ac power LED. When
the ac power LED is lit, it indicates that sufficient power is coming into the power
supply through the power cord. During typical operation, the ac power LED is lit.
For any other combination of LEDs, see the
Problem Determination and Service
Guide
on the IBM
System x Documentation
CD.
v
DC power LED:
Each hot-swap ac power supply has a dc power LED. When the
dc power LED is lit, it indicates that the power supply is supplying adequate dc
power to the system. During typical operation, both the ac and dc power LEDs
are lit. For any other combination of LEDs, see the
Problem Determination and
Service Guide
on the IBM
System x Documentation
CD.
v
IN OK power LED:
Each hot-swap dc power supply has an IN OK power LED.
When the IN OK power LED is lit, it indicates that sufficient power is coming into
the power supply through the power cord. During typical operation, both the IN
OK and OUT OK power LEDs are lit. For any other combination of LEDs, see the
Problem Determination and Service Guide
on the IBM
System x Documentation
CD.
v
OUT OK power LED:
Each hot-swap dc power supply has an OUT OK power
LED. When the OUT OK power LED is lit, it indicates that the power supply is
supplying adequate dc power to the system. During typical operation, both the IN
OK and OUT OK power LEDs are lit. For any other combination of LEDs, see the
Problem Determination and Service Guide
on the IBM
System x Documentation
CD.
