Light path diagnostics LEDs description
This topic provides a description of the light path diagnostics LEDs.
The following table describes the server LEDs to help you detect the location of the
problems. For the location of the server LEDs, see “Storage book LEDs” on page
161, “Compute book LEDs” on page 162, “DIMMs and microprocessor LEDs” on
page 163, “Half-length I/O book LEDs” on page 164, “Full-length I/O book LEDs”
on page 164, “Standard I/O book LEDs” on page 165, and “Power-supply LEDs”
on page 165.
Note: Check the IMM event log or the system-event log for additional information
before you replace a FRU. See Chapter 5, “Parts listing, System x3850 X6 and x3950
X6 Types 3837 and 3839,” on page 205, to determine which components are
customer replaceable units (CRU) and which components are field replaceable
units (FRU).

LED Description
3V battery error LED When this LED is lit, it indicates that a standard I/O book battery
error has occurred
AC power LED Each hot-swap power supply has an ac power LED and a dc power
LED. When the ac power LED is lit, it indicates that sufficient power
is being supplied to the power supply through the power cord.
During normal operation, both the ac and dc power LEDs are lit
Board error LED When this yellow LED is lit, it indicates that the book board error
has occurred.
Check log LED When this LED is lit (yellow), it indicates that there are errors that
require further diagnosis. Check the IMM event log for additional
information. See “Event logs” on page 168 for more information
about event logs.
DC power LED Each hot-swap power supply has a dc power LED and an ac power
LED. When the dc power LED is lit, it indicates that the power
supply is supplying adequate dc power to the system. During
normal operation, both the ac and dc power LEDs are lit
DIMM error LED When this LED is lit, it indicates that a memory error has occurred .
Drive activity LEDs These LEDs are on SAS or SATA hard disk drives and solid state
drives. Each hot-swap drive has an activity LED, and when this LED
is flashing, it indicates that the drive is in use. When this LED is
solid, it indicates that the drive is powered on but not in use.
Drive status LEDs These LEDs are on SAS or SATA hard disk drives and solid state
drives. When one of these LEDs is lit, it indicates that the drive has
failed. When this LED is flashing slowly (one flash per second), it
indicates that the drive is being rebuilt. When the LED is flashing
rapidly (three flashes per second), it indicates that the controller is
identifying the drive.
Ethernet activity LED 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.
Ethernet link LEDs When these LEDs are lit, they indicate that there is an active link
connection on the 100BASE-TX, 1000BASE-TX, or 10GBASE-TX
interface for the Ethernet port.
Fan error LED When this LED is lit, it indicates that a fan has failed, is operating
too slowly, or has been removed.
