10.1.3 Audible warning
10.1.3 Audible warning
An audible warning sounds for some critical errors relating to the PSUs on the module. The orange
warning LED (see Orange warning LED on page 65) accompanies the audible warning.
The warning sounds when only one of the two PSUs is powered and turned on. Check that:
l The rocker switch on both PSUs is in the on position
l Both PSUs are connected to the mains supply
If the audible warning continues, there might be a fault with one or both PSUs. Before investigating
further, switch off the audible alarm by navigating to the 1-2-5-3 Critical Errors screen. The orange
warning LED remains on until you resolve the issue.
For more information about identifying and replacing a failed PSU, see the nShield Connect Power
Supply Unit Installation Sheet .
10.1.4 Orange warning LED
If the orange warning LED (see Orange warning LED on page 65) is on, the module has encountered
a critical error (for example, overheating or PSU failure) that may require immediate action. To find the
cause of a critical error, navigate to System information > View h/w diagnostics > Critical Errors.
10.1.5 Checking the physical security of the module
The physical security measures implemented on the module include tamper detection. This warns you
