The LCD shows the error 'SWC5008 Critical'.
SWC5007 might also be displayed.
According to this forum thread of Dell, this is related to a communication issue with the left front Panel, either by physical connectivity problems, so check the cables.
It could also be caused by the firmware of the lifecycle controller.
Excerpts quoted from that article:
This warning message is usually a cosmetic warning when momentary communication with the left front panel is lost. Mostly iDRAC updates fixed an issue wherein the Left Front Panel (LED, Quick Sync) intermittently stops communicating and logging errors SWC5008 and SWC5007.
Make sure the iDRAC and BIOS are up to date.
However, if the problem persists, a check as follows may be required.
This article describes how to upgrade the lifecycle controller, provided the physical connectivity of the mentioned cables, is given.
This article will be how to upgrade the iDRAC lifecycle controller as an example to firmware 126.96.36.199.
For this process the FortiNAC hardware will be rebooted to enter the lifecycle controller.
The iDRAC lifecycle upgrade itself will take a considerable amount of time, so this should be planned with a failover to an HA secondary device or in a maintenance window.
The steps are photo documented from a lab.
Note that other error codes may need other steps and solutions.
1) The firmware image from Dell will be necessary:
2) Rename the downloaded firmware file to something to be comfortable typing with a US keyboard layout.
Verify the checksum of the file.
- Save the file on a plain USB stick/thumb drive in FAT32/VFAT file system format.
The FortiNAC hardware should have a front panel with USB ports for this.
- Prior to attempting this, make sure to plan about an hour for the upgrade.
A failover (shutdownNAC; sleep 15; shutdownNAC -kill) should be performed, then reboot the node.
1) entering the setup, displays the firmware version:
2) It will take a little time.
3) The setup wizard is displayed. If you had set this up previously, it may not show up. Step 1.
4) Setup Wizard Step 2.
5) Setup Wizard Step 3.
6) IP auto configuration as part of step 3.
7) Step 5 of the wizard as Summary.
8) Home screen on the lifecycle controller - launch the 'firmware update' on the left-hand side.
9) The following wizard will be shown - in this example, the 'local drive' is used, that could be a plain USB stick/thumb drive in FAT32/VFAT file system format.
10) Confirm the USB port and manually enter the filename as it is stored on the thumb drive.
11) Filename entered:
12) Summary prior updates - if it is accepted, the actual upgrade process will start, that will take its time.
13) Lifecycle controller image verification.
14) Upgrade started:
15) During upgrade:
16) The unit will finish and reboot into the Lifecycle controller as an example.
17) Enter the Lifecycle log:
18) That will also display a loading screen again.
19) The log should display the controller update was successful, such as:
20) It is also possible to verify with the 'View Current Versions' under the 'Firmware update' section.
21) Example versions here after the upgrade of the Lifecycle controller and the Remote access Controller.
