I was able to resolve my OOB access from other network ranges issue by removing the OOB IP address and re-applying it using the following commands: SWITCH(config)#interface out-of-band SWITCH(config-if)#no ip address SWITCH(config-if)# SWITCH(config)#interface out-of-band SWITCH(config-if)#ip address 1.1.1.x 255.255.255.0 1.1.1.1 SWITCH(config-if)# SWITCH#copy running-config start This operation may take a few minutes. Management interfaces will not be available during this time. Are you sure you want to save? (y/n) y Strange that the OOB config was showing when I did a show run but refused to work until the IP address was re-applied.  Hopefully nothing else previously configured needs to be reconfigured after this update.
Hello everyone, First off, let me say that I am very new to the networking world.  I usually work with servers/desktops/laptops. Our network team isn't familiar with Dell switches, so I'm having to do this myself. I appreciate your understanding.  We bought an 8024 to use as a back-end network to run our server backups. It's not going to touch our production network. So I followed the manuals and setup the OOB management port. That was working fine. Then I decided to upgrade the firmware before we started using the switch. The switch has 3.x.x.x firmware (I'd have to go check the actual version if you need to know it), so I followed the instructions and loaded the interim firmware version a.1.0.19 in preparation to load 4.1.0.19. I ran "update bootcode" (which seems to have gone successfully), and the switch rebooted. After the reboot the OOB port doesn't seem to work. The OOB port still has the correct IP, and one of the lights turns on, but the activity light never flashes. Without the OOB port working, I don't know how to download the full 4.1.0.19 firmware from my TFTP server. Any help is greatly appreciated.
