But you are a professional. You do this:
tftp 192.168.1.100 get 5130_24G_4SFP_7.10.R3238.ipe The cursor blinks. This is where you contemplate your life choices. A 30MB file over 100Mbps Ethernet takes 5 seconds. Over a slow TFTP transfer because your laptop is on WiFi? It takes an eternity.
The 5130 has a USB port. Copy the .ipe to a FAT32 USB stick, plug it into the switch, and type copy usb0:/firmware.ipe flash:/ . It’s faster and less likely to corrupt. Act III: The Surgery (The Boot Loader Whispers) Here is where most guides lie to you. They say: "Just type boot-loader."
