Stack Unit in Card-Problem State Due to Configuration Mismatch
• Problem: A stack unit enters a Card-Problem state because there is a configuration mismatch between the logical provisioning stored
for the stack-unit number on the master switch and the newly added unit with the same number.
• Resolution: From the master switch, reload the stack by entering thereload command in EXEC Privilege mode. When the stack
comes up, the card problem will be resolved.
Upgrading a Switch Stack
To upgrade all switches in a stack with the same Dell Networking OS version, follow these steps.
1 Copy the new Dell Networking OS image to a network server.
2 Download the Dell Networking OS image by accessing an interactive CLI that requests the server IP address and image filename, and
prompts you to upgrade all member stack units.
EXEC Privilege mode
upgrade system { flash: | ftp: | scp: | tftp: | usbflash: } partition
Specify the system partition on the master switch into which you want to copy the Dell Networking OS image. The system then
prompts you to upgrade all member units with the new Dell Networking OS version.
The valid values are a: and b:.
3 Reboot all stack units to load the Dell Networking OS image from the same partition on all switches in the stack.
CONFIGURATION mode
boot system stack-unit all primary system partition
4 Save the configuration.
EXEC Privilege

5 Reload the stack unit to activate the new Dell Networking OS version.
