I have been working a lot with the Dell N-series over last few years, and now the N2248-ON which can run OS10 as well as the default OS6. We upgraded firmware to the latest 126.96.36.199 and all seemed to go well. Somehow it did not and hosed both primary/secondary firmware. The device was boot looping – the only option was to drop into ONIE Recovery and re-install the firmware. Here are the steps I used:
The ONIE recovery area runs a version of Linux. First check out your NIC to make sure it finds it:
Perfect! My laptop is 192.168.1.99 – and connected directly to the out of band MGMT port.
Next we will TFTP the file up. This file is located in the software archive you download from Dell – Its located in the “Otherfiles” folder. In this case the file name is onie-installer-x86_64-dellemc_n22xx_188.8.131.52. Next I put this on my TFTP server and we can start the install.
First lets turn off the ONIE-Discovery attempts with the onie-stop command.
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
This will allow you to access each of your switches from the CMC. Check the below screenshot out.
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)#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.
