Faulty CPU needs swap out? 1

[NPRVTXer]

Hi all,
I'm currently having an issue with our 2400 IPXs at one of our sites where the 1 system (CMOD shows the CPU in standby)CPU will not come on line. It has a WDT light indicator and the LED read out indicates 0. When I do a MEM_HDD all saves from that CPU fails. when I atempt to log off sys 1 Flash drive I get a "I/O timed out" we have disabled the default cpu swap out using the ASYD command every 24 hrs until we can figure out what needs to be done to correct the issue. We do have a spare CPU modual if needed to replace. all sw, ph36 cards have been tested and checked good. My question what is the replacement CPU swap procedure. Do we have to power down the entire PBX for this swap out? any info would be of great help.

If you have redundant CPU's then you need to load the flash card with the same version as the on line CPU. Use the CFCS command to remove the flash drive from the working CPU. Use the compact flash tool (from MAT CD) to back up the database. Load the generic files on to the flash, then load the database. Reinstall the CF use the CFCS command to restart the CF. Test.

Thanks for the response Belevedere,
yes we do have redundant CPU's, I did perform a MEM_HDD backup and used that from the active CPU to overwrite the suspected Flash drive from the suspected faulty CPU. My results where that the CPU status indicator on the suspect CPU went from a steady 0 to a spinning indication that the processing status had completed successfully and the WDT (Watch Dog Timer) indicator went out. My problem is I still cant log on/off on the suspect Compact Flash card using the CFCS command.I still get "I/O Timed out". It also shows under CMOD command that the suspected CPU is in standby mode, even though no "stb" in CPU status readout (just spinning). I went one step further and replaced the suspected CF with another CF from another PBX at another site and got the same results after over writing the CF. one other thing... I noticed that at another site's PBX both active and standby CPU's LAN ports where flashing active. the suspected CPU LAN shows no activity. only the connectivity light is illuminated. Can I hot swap the CPU module?

Thanks again

You can shut down the defective CPU and hot swap it. Make sure that the redundant time division is on side 0. I suggest you perform this after hours as a precaution.

Well the "Hot Swap went well but had the same results as I had when I reformatted and re-wrote the original Flash drive. A spinning status display window and no WDT light. I'm still concerned that the LAN connection only shows the connectivity light but no activity light. Can anyone point me in the direction of the sequence of loading the initial programming to the flash? I know that there is a boot file on the flash drive directory but is there anything else?

Thanks again Troy

You need a copy of the CF tool (found on MAT CD). You will need a CF adapter on your PC. You will also need the generic software CD. Run the CF tool and use the option for initial load. This will take around 5 minutes to complete. This will format the CF and load the generic files. When completed, install it into the CPU. Bring the CPU up with the switch setting on 1 for a basic system load. Once it is up switch to 2, to retain the program. Perform a back up to get the database on to the CPU flash.

Well Belevedere... you have saved the day once again after using the generic software from the Cd to format and over write the basic program set the sense wheel to "1" and powered up the CPU in a matter of 2 min we have "S T B" on the status read out! I set the Sense wheel to "2" after the load and did a MEM_HDD back up and we are operating normally! The power fluctuation that we suffered must have corrupted the CF data and simply needed to be reloaded. Congrats to you and THANK YOU!!!!
