The following error appears on the health tab of the Integration Data Protection Appliance (IDPA) Appliance Configuration Manager (ASM) UI accessible at " https://<ACM_IP_ADDRESS>:8543": Figure 1: Screenshot of Event Message Summary on ACM Figure 2: Screenshot of "Power Supply Redundancy is Lost" message. A dial-home may also be sent to Dell Technologies with the following description: SymptomCode: 483 Category: Status Severity: Critical Status: Unknown Component: IDPA Server ComponentID: xxxxxxxxxxxxx-IDPA Server CallHome: Yes CDATA: {Rac FQDN=iDRAC-xxxxxxx, System ServiceTag=xxxxxx, Chassis Name=Main System Chassis, Device Display Name=System, System FQDN= x xxxxxxxxxxxxxx.com, FQDD=System.Embedded.1, Chassis Service Tag=xxxxxxx, Current Status=Critical, Message ID=RDU0012} Alternately, from the appliance CLI, the failure can also be confirmed. Open PuTTY to the ACM server and login as 'root' user . Issue the following command to query the disk status: #showfru power --> This output will provide PSU status, Part number & serial # informationExample: Shows faulty PSU in Slot 1dp4400:~ # showfru power Collecting Data............ _________________________________________________________________________________________ | ID| Status | Redundancy| Model | Part# | Serial# | FW Version| |========================================================================================| | 1 | Failed | Fault | PWR SPLY,1100W,RDNT,LTON| 0CMPGMA01| CXXXXXXXXXXXXX| 00.23.32 | | 2 | OK | Full | PWR SPLY,1100W,RDNT,LTON| 0CMPGMA01| CXXXXXXXXXXXXX| 00.23.32 | Things to note: The DP4400 supports two 1100 W or 750 W mixed mode High Voltage Direct Current (HVDC) power supply units (PSUs). If two PSUs are installed, both PSUs MUST be the same type and power rating. PSUs support both 120v and 240v except for 'Titanium' models which support only 240v. The system requires at least one functional PSU for normal operation. On power-redundant systems, remove and replace only one PSU at a time in a system that is powered ON.
The power supply unit may have failed on the appliance, or the appliance lost power due to scheduled maintenance. There may also be a genuine case of PSU unit failure. If the power has been restored after the interruption, users can validate the status of the PSU using commands provided. Deem this alert false positive if this was a temporary interruption. If not, Dell Support can be engaged for assistance and a support request can be opened for a work order.
Steps on how to Identify a Failed or Faulty Power Supply on the DP4400 Open PuTTY to ACM and login as 'root' user (ACM-Command line Interface): Run the following command to fetch the Power supply health status: # showfru power --> This output will provide PSU status, Part number & serial # informationExample: Shows faulty PSU in Slot 1dp4400:~ # showfru power Collecting Data............ _________________________________________________________________________________________ | ID| Status | Redundancy| Model | Part# | Serial# | FW Version| |========================================================================================| | 1 | Failed | Fault | PWR SPLY,1100W,RDNT,LTON| 0CMPGMA01| CXXXXXXXXXXXXX| 00.23.32 | | 2 | OK | Full | PWR SPLY,1100W,RDNT,LTON| 0CMPGMA01| CXXXXXXXXXXXXX| 00.23.32 | dp4400:~ # NOTE: If both the Power supplies report status as 'OK' and Redundancy as 'Full', that implies that the Power is restored and the PSU is healthy. The alert can be ignored. The following steps can be reviewed if PSU status reports a fault. Physically inspect the PSU. Check the illuminated translucent handle of the PSU. The indicator shows whether power is present or a power fault has occurred Figure 3: The illuminated translucent handle of the PSU indicator shows whether power is present or a power fault has occurred. Figure 4: PSU Status Indicator Codes How to Remove and Replace the PSU: Removal: Unlatch and lift the optional cable management arm at the back of the system if it interferes with the PSU removal. Disconnect the power cable from the power source and from the failed PSU, and remove the cable from the strap attached to the PSU handle. Press and hold the release latch and slide the PSU out of the system by using the PSU handle. Figure 5: Press and hold the release latch and slide the PSU out of the system. Replacement: Slide the PSU into the slot until it is fully seated and the release latch snaps into place. Relatch the cable management arm , connect the power cable to the PSU, and plug the power cable into the power outlet. Attach the power cable to the PSU with the strap attached to the PSU handle When installing it, hot swapping, or hot adding a new PSU, wait for 15 seconds for the system to recognize the PSU and determine its status. PSU redundancy may not occur until discovery is complete. The PSU status indicator turns GREEN to signify that the PSU is functioning properly. Procedure Reference: Follow the "Remove and replace power supply" section from the "Dell PowerProtect DP Series Appliance Service Procedures Guide for DP4400" for replacement steps.
