I have 4 Powerconnect 3024 stacked. The previous administrator who is no longer with our organization set up these switches. I have some ports on the web interface admin page that show their status as BLK. I did not find any information in the docs about what this means? Any help would be appreciated.

Also and this may seem like a strange question, but the 4 switches as stated are connected together with stack cables. Then they are also connected with uplink cables on the front. This is my first experience with Dell switches, but I assume that since the stack cables are installed, these uplink cables are not necessary. Is this correct?

Thanks for any help.
