Dell PowerConnect M6220 and 6348M EoL

Greetings, 

I have to Dell enclosures in my department, and we want to know the End Of Life of these two machines and also of their software. 

I do not know if this is already a thread in the forums, but I have been searching and have not found it. 

The machines are:

• Dell PowerConnect M6220 with software version 5.0.1.3
• Dell PowerConnect 6348M with Software version 5.1.7.5

Thanks in advance. Best regards

Francisco
