E5600SG controller seven-segment LED status and error codes

The E5600SG controller seven-segment LEDs display status and error codes during the time when the appliance powers up and while the hardware is initializing. You can use these codes to determine status and troubleshoot errors.

When reviewing status and error codes on the E5600SG controller, you should look at the following types of codes:

General boot-up codes
Represent the standard boot-up events.
Normal boot-up codes
Represent the normal boot-up events that occur in the appliance.
Error codes
Indicate issues during the boot-up events.

The codes that appear differ depending on the installation version. You can determine the installation version by referring to Determining the StorageGRID Webscale appliance installer version.

StorageGRID Webscale controls only the following LED lights on the E5600SG controller and only after the pre-grid environment has started:

The following LED decimal points are not used by the StorageGRID Webscale appliance:

General boot-up codes

During boot-up or after a hard reset of the hardware, the Service Action Allowed and the Service Action Required LEDs come on while the hardware is initializing. The seven-segment LED displays a sequence of codes that are the same for E-Series hardware and not specific to the E5600SG controller.

During boot-up, the Field Programmable Gate Array (FPGA) controls the functions and initialization on the hardware.

Code Indication
19 FPGA initialization.
68 FPGA initialization.
... FPGA initialization.

This is a quick succession of codes.

AA Platform BIOS booting.
FF Bios boot-up complete.

This is an intermediate state before E5600SG controller initializes and manages LEDs to indicate status.

After the AA and FF codes appear, either the normal boot-up codes appear or error codes appear. Additionally, the Service Action Allowed and the Service Action Required LEDs are turned off.

Normal boot-up codes

These codes represent the normal boot-up events that occur in the appliance, in chronological order.

Code, if version is 1.4 or earlier Code, if version is 1.5 or later Indication
MB HI The master boot script has started.
PP PP The platform FPGA firmware is checking for updates.
HP HP The HIC host interface card is checking for updates.
RB RB After firmware updates, the system is rebooting, if necessary.
FP FP The firmware update checks have been completed. Starting the process (utmagent) to communicate with and manage the E2700 controller. This process facilitates appliance provisioning.
SE HE The system is synchronizing with the E-Series operating system.
SI HC The StorageGRID Webscale installation is being checked.
IM HO Installation management and active interfacing are occurring.
SG HA The Linux operating system and StorageGRID Webscale are running.

Error codes

These codes represent error conditions that might be shown on the E5600SG controller as the appliance boots up. Additional two-digit hexadecimal codes are displayed if specific low-level hardware errors occur. If any of these codes persist for more than a second or two or if you are unable to resolve the error by following one of the prescribed troubleshooting procedures, contact technical support from the NetApp Support Site at
