Dell FX2 console to internal switches

The Dell FX2 is a pretty awesome piece of hardware. I mostly only work on it from the networking side.

From the CMC you can console to each of your switch modules. I had a hard time finding documentation on the very simple command to do this. From doing a quick ? and scanning through each command I found “Connect” Pretty fast, and knew that would be it …. but connect to what?

I finally found from searching a different help command that you can do

Connect switch-1

or

connect switch-2

This will allow you to access each of your switches from the CMC. Check the below screenshot out.

Enabling SSH on Dell Powerconnect 5000/6000/7000

No one is probably trying to even do this anymore due to the new Dell switching lines, but thought I would see if I could help. I had this issue the other day, and it took a good bit of googlefu before I could find my answer .

The problem I had was getting SSH enabled on a Dell PowerConnect 7048P. I created my user/passwords , and then generated my certificate, and then enabled the SSH server.. I got this error

PC-7048(config)#crypto key generate rsa

RSA key generation started, this may take a few minutes……..
RSA key generation complete.

PC-7048(config)#

PC-7048(config)#ip ssh server

SSH could not be enabled.

Hmmm… Why is that, all of my needed components are there, so why is it not working. The reason is there is no Cert to be used by SSH. These models use the Digital signature Algorithm (DSA) Certificate instead of the RSA cert. SO we need to create the DSA Cert.

PC-7048(config)#crypto key generate dsa

DSA key generation started, this may take a few minutes………………….
DSA key generation complete.

PC-7048(config)#ip ssh ser

No error!! and it works just fine.
