Ethernet1/Ethernet2 activity LEDs
There are two Ethernet activity LEDs, one for each Ethernet controller in
your server. When each LED is lit, it indicates that there is activity between
one of the Ethernet controllers and the network.
AC1 power LED
When this LED is lit, it indicates that the AC1 power cord is connected to an
ac power source.
AC2 power LED
When this LED is lit, it indicates that the AC2 power cord is connected to an
ac power source.
AC-R power LED
When this LED is lit, it indicates that both the AC1 and AC2 power cords
are connected to an ac power source and three power supplies are
installed in the server. It indicates that the server is operating with
redundant ac power.
PS1/PS2/PS-share power LEDs
This LED is on each hot-swap power supply. When this LED is lit, it
indicates that the power supply is installed and providing dc power to the
server. During typical operation for a server with two power supplies, both
the AC1 and AC2 power LEDs and both the PS1 and PS2 power LEDs are
lit. During typical operation for a server with three redundant power
supplies, both the AC1 and AC2 power LEDs and the PS1, PS2, and
PS-share power LEDs are lit. For any other combination of LEDs, see the
Hardware Maintenance Manual and Troubleshooting Guide on the IBM
xSeries Documentation CD.
