Rear view
The following illustration shows the LEDs on the rear of the server.
AC power LED: Each hot-swap power supply has an ac power LED that is visible
from the rear of the server. The power supply also has an ac power LED and a dc
power LED on the top of the power supply, visible when the server cover is
removed. When the ac power LED is lit, ac input to the power module is present
and within specifications. During typical operation, both the ac and dc power LEDs
on the top of the power supply are lit. For any other combination of LEDs, see
"Power LED errors" on page 130.
Ethernet link LEDs: When these LEDs (one for the Remote Supervisor Adapter II,
two for the network) are lit, they indicate that the related Ethernet link is operational.
Remote Supervisor Adapter II activity LED: When this LED is flashing, the
Remote Supervisor Adapter II is functioning normally. When the LED is lit
continuously, there is a problem with the Remote Supervisor Adapter II. When the
LED is off, the Remote Supervisor Adapter II is not functioning.
Remote Supervisor Adapter II power LED: When this LED is lit, it indicates that
power is being supplied to the Remote Supervisor Adapter II.
Attention LED: When this LED is on steady, it indicates that the adapter in the
corresponding slot is ready to be removed (hot-pluggable adapter only) or there is a
problem with the adapter. When this LED is flashing, it indicates that an operation is
in progress or that the adapter requires attention, depending on the operating
system.
Locator LED: Use this blue LED to visually locate the server if it is in a location
with numerous other servers. A locator LED is also on the operation information
panel on the front of the server. You can use the Management Processor Assistant
(MPA) in IBM Director to cause this LED to be lit, off, or flashing (see the User's
Guide on the IBM xSeries Documentation CD for more information on IBM
Director). If the server is connected to an RXE-100 Remote Expansion Enclosure,
pressing the Locate button on the enclosure causes this LED to be lit.
Note: This LED flashes while the server is being turned on or restarted, and turns
