Status LEDs and System Buttons
Troubleshooting the Hardware 3-9
ID LEDs blink. The blinking LEDs help you locate a specific enclosure that may be
mounted in a heavily populated rack.
In Windows, you can cause the system ID LEDs to blink by issuing the Start Slot
Identification command from ftSMC. To stop the system ID LEDs from blinking, press
the system ID button a second time or issue the Stop Slot Identification command
from ftSMC.
In Linux, you can cause the system ID LEDs to blink by using the ftsmaint
identify start path command. To stop the system ID LEDs from blinking, use the
ftsmaint identify stop path command.
You can also use the VTM console to cause the system ID LEDs to blink. From the
VTM console, click Remote Control, and then click SID LED Switch.
NOTE
You must use the same method to stop the system ID
LEDs from blinking as you had used to start them blinking.
The NMI (
nonmaskable interrupt ) button inititates an NMI, which saves the contents of
memory to a dump file, and then restarts the operating system. For more information,
see “Using the NMI Button to Create a Dump File” on page 3-21.
LEDs on the Back of the CPU-I/O Enclosure
There are several LEDs on the back of the CPU-I/O enclosure (refer to Figure 1-3).
The power supply LED lights steady green to show that the power supply is
receiving power. See Ta bl e 3- 3 for details.
The system ID LED identifies the CPU-I/O enclosure. It is green when lit. See
“CPU-I/O Enclosure Status LEDs” on page 3-5 for details.
