  Upgrading an Old Nexus 3048 to Current NX-OS Posted on 2018/11/16 Yeah, I know. I’m supposed to be a Wi-Fi guy. However, I sometimes still have to touch routers and switches. I have some help for you if you need to upgrade some old Nexus switches. The Nexus 3048s are great DC caliber gig switches with proper front-to-back airflow. Used ones are really cheap and I think they make great management switches, which is what I’m using them for. If you have a Cisco Nexus 3048 with an older release of NX-OS on it, you need to go through several upgrades to get it to NX-OS v7. Here’s a walkthrough on the procedures. If you find you already on v6, for example, you can skip the 5.x step. Upon initial boot, you will need to abort Power-On Auto Provisioning. You will then be prompted for the admin password. Skip the basic configuration dialog. After a few moments, you will be able to login with the admin credentials you set during boot. I suggest downloading all the required

  Recovering Fabric Interconnects When You Do Not Have Working Images on The Fabric Interconnect or The Bootflash You can perform these steps when both or any fabric interconnect goes down during firmware upgrade, gets rebooted, and is stuck at the loader prompt, and you do not have working images on the fabric interconnect. Procedure Step 1 Reboot the switch, and in the console, press  Ctrl+L  as it boots to get the loader prompt. Note   You may need to press the selected key combination multiple times before your screen displays the loader prompt. Example: loader> Step 2 Configure the interface to receive the kickstart image through TFTP. Enter the local IP address and subnet mask for the system at the loader> prompt, and press  Enter . Example: loader> set ip 10.104.105.136 255.255.255.0 Specify the IP address of the default gateway. Example: loader> set gw 10.104.105.1 Boot the kickstart image file from the required server. Example: loader> boot tftp://10.104.10
