Viewing boot-up status and reviewing error codes on the controllers

The seven-segment LEDs show status and error codes when the appliance powers up, while the hardware is initializing, and when the hardware fails and must back out of the initialization. If you are monitoring the progress or troubleshooting, you should watch the sequence of the codes as they appear.

1. During boot-up, view the seven-segment LED display to monitor progress.
2. To review error codes for the E5600SG controller, see the seven-segment LED status and error code information.
3. To review error codes for the E2700 controller, see the E2700 controller documentation on the Support Site.
