Dell Networking N4000 Series, Firmware Version 6.2.6.6,A08
Restart required AUTO INSTALLED This file was automatically installed as part of a recent update. If you are experiencing any issues, you can manually download and reinstall.Both Dell Networking N4000 Series switches and Dell PowerConnect 8100 Series shares the same firmware image version (for example., N4000v6.2.6.6.stk). Dell Networking PC8100 series switches can be stacked with Dell Networking N4000 series switches with the entire stack required to run 6.0.0.8 or later firmware (6.2.6.6). Dell Networking PC8100 series switches can support both 5.x and 6.x firmware versions, but Dell Networking N4000 can support only 6.0.0.8 and later firmware versions.
Please refer to the Release Notes for fixes and enhancements available in this release. "Release Notes" are included in the zip file - "Dell Networking_6.2.6.6_Release_Notes".
Please follow software update instructions included in the zip file - "Upgrading Dell Networking N4000 Series Switches From Version 6.x.x.x to 6.2.6.6 Firmware.pdf".
Note: PowerConnect 8100 Series switches with B1 CPU Revision require firmware version 5.1.0.1 or later (6.2.6.6) and cannot be downgraded to earlier releases. If this unit is to be deployed as a member within a stack, the entire stack will be required to run 5.1.0.1 or later firmware (6.2.6.6). The improved CPU version XLP308H-B1 version is not compatible with firmware 5.0.x.x. The 'show version' CLI command in the 5.1.0.1 release has been improved to identify the CPU version of the switch.
