PALM LED is steady on
If the PALM LED of the MPU is steady on, it indicates that exceptions have occurred to the power supply
system. The following reasons might apply:
• Mismatch between the power supply and power consumption. For example, if an HSR6808 is
installed with a 650 W power module but two SAP-48GBE modules, the power available is not
sufficient for the whole power consumption and one SAP module cannot be powered on.
• Intermixing of AC and DC power modules and different specifications of the inserted power
modules.
To solve the problem, examine the output for the above reasons on the serial terminal and the software
management tool.
If the problem persists, record the above information, and contact your local sales agent.
