ELS10-26 Diagnostics and Troubleshooting

The operational parameters of the ELS10-26 software are also protected by a checksum comparison. When the ELS10-26 reboots, if the operational parameters of the ELS10-26 fail a checksum test due to a power failure in the midst of a previous update, the ELS10-26 automatically uses its backup version of the parameters.

Note: A backup version of the operational parameters is always stored in non-volatile memory before any update is attempted.

5.1.4 Power-up Diagnostics Results

After completion of the power-up diagnostic sequence, both the Power (Pwr) and Ready LEDs located on the front panel of the ELS10-26 should be on.

5.2 RESPONSES TO FAILURES AT POWER-UP

How the ELS10-26 responds to failures detected during power-up depends on the seriousness of the failure. For example, it will operate if a non-critical component, such as the out-of-band management port, fails diagnostics. However, in the event of a critical failure, such as a failure of the main element processor, the ELS10-26 will halt execution and will not boot to operational mode.

5.3 STATUS AND ACTIVITY INDICATORS

The front panel of the ELS10-26 includes LEDs that indicate the status or activity of various system components. Figure 5-1 shows the ELS10-26 front panel LEDs and buttons. The LEDs and buttons are described in Tables 5-1 and 5-2.
