Monitoring the AT-FCX module

About monitoring the modules

The AT-FCX module has four LEDs. The LEDs indicate whether it is functioning normally, the module's readiness for I/O traffic, or whether there are any problems with the hardware. You can also identify any hardware failure associated with the module from the error messages displayed on your storage appliance console.

This section also describes the different types of messages that appear on the storage appliance console in response to a command monitoring the AT-FCX.

Location of the module LEDs

The AT-FCX module is in the middle of the back of the disk shelf. It has a perforated carrier. The following illustration shows the location of the LEDs for an AT-FCX.

Note
Because module A on the DS14mk2 AT is inverted, the location of the module A LEDs is the inverse of what is shown in the preceding illustration. The Fault LED is amber. The other three LEDs are green. See LED status on the AT-FCX for an illustrated explanation of the LED functions.

LED status on the AT-FCX

The following illustration is of the second sheet of the quick reference cards that come with your disk shelf.

Note
The rest of the second sheet of the quick reference card identifies the LED status conditions for the power supply and the integrated fan module.

AT-FCX console error messages

The following error messages appear on the storage appliance console if an SES element on the AT-FCX module fails. See Hot-Swapping the AT-FCX module for more information. The output displayed on the console is similar to the following example.

Example
