Dell Powerconnect 6248 stack troubleshooting
Hi,
I have 6 Dell PC6248 stacked together and the first one is master. Couple weeks ago we had a power outage. After power went back, the fifth refused to boot up and it keeps flashing the Diag light so that I thought the switch is bad. I have ordered another PC6248 online and reset it to factory default and configure the firmware to 3.3.4.1 which is same as my original stack firmware.
Based on the search online, i thought after i plug back the stacking cable/module and power it on, it should automaticaly communicate to the master switch and get settings configured, however, it didnt work and both 1 and master light on.
Then I checked my old fifth switch which i thought it was a BAD one, after I boot it on seperately, it shows its correct membership as 5 and master light was on. I can login to the switch which shows there is nothing wrong with this switch.
After this, I came up an conclusion that the stacking module or stacking cable must be faulty. So I ordered some stacking module and cables which is same as my current one. After I replace the stacking module and boot the 5th swtich in the stack, it shows both master and 5 light. It didn't communicate with the stack either.
Can anyone tell me what could be the problem? DO i need to restart the whole stack?

When I get into the UI interface, the Stack Summary shows the Switch ID 5 is unassigned and Stack port summary doesn't even shows the unit 5 stacking information. The working stack switches are up for about 30 days. Do I need to reboot the whole stack?

Hi,
Restarting the stack is the best option if you have already tried the cables and switch.
