PC6248 Reformat

Note that using the command show dir seems be a good stress test. Even switches that pass the check disk commands below can fail running the show dir command. I don't think I've had trouble with switches that can successfully run show dir.

Special Menu

Do this with help of Dell support only.

1. At [Boot Menu] prompt enter "30".

2. Password is "pc62xxkinnick"

3. Lots of interesting diagnostic tools available in new menu.

Hello Ben,

Here are some quick fix steps to try on the switch.

If you PC62XX having problem updating firmware do the following on the
UNSTACK SWITCH(if you do this on a stack it will only do the master switch):

This are some steps from engineering:

          1. Check if the file system is corrupted with the following
             DevShell commands(following this steps)
          2. Delete backup image
          3. Download the new image via tftp server
          4. Set the boot to new image
          5. Reboot
          6. Update bootcode
          7. Download the new image via tftp server ( for the 2nd image)

Here are the command on the switch:
1) When the stack is booted, on the master perfor the following command
to see if the flash file is corrupted

Console# Devshell chkdsk('/DskVol/',0,0x200)

2) Perform this command if the flash file is corrupted, Checkdsk will
fix if any errors

Console# Devshell chkdsk('/DskVol/',2,0x200)

3) Perform this command again to see if the flash file is Ok

Console# Devshell chkdsk('/DskVol/',0,0x200)

4) Reboot the switch

Console# Reload.


This is what will happen if we have a flash coruption:
