IO Module Indicator LEDs

Last modified
<< PrevNext >>

The I/O module is different depending on whether you refer to the head unit or the EBOD enclosure. For the appliance, the I/O module is the 'Controller whereas for the EBOD enclosure, the I/O module is the 'EBOD canister'. This page explains the various LEDs that are present for the I/O modules in the system in the following sections:

 

Monitoring LEDs for the Controller

Each appliance controller has indicator LEDs shown in the figure below.

If the fault LED is lit, it indicates that there is a problem with the controller module. The suggested course of action is to try to reboot the controller. For details on how to reboot your appliance controller, refer to the Web UI guide. Please contact StorSimple support if rebooting the controller does not resolve this issue.

Identifying Active Controller on the Appliance

There are many situations that require a user to locate the active controller. To determine which of the two controllers is the active controller in the appliance unit, perform the following steps.

  • Look at the appliance backplane.
  • Locate the LED above the DATA2 port. Use the diagram below as an aid.

  • If this LED is blinking, then it indicates that controller is the active controller and the other one is the standby controller.
