Upgrading Cisco Switch Firmware Slow

I recently upgraded a Cisco 3560X switch.

I upgraded from 12.2(53)SE2 to 15.0(2)SE8.

I thought this would take 5 minutes max. After ten minutes I was worried. I connected a console cable and found the console reporting “Front-end Microcode IMG MGR: Programming device 0…rrrrrrwsssssssssssssssssssssspssssssssssssssssssssspsssssssss”

Solution:

After googling I have discovered it is quite normal to take up to 40 minutes due to an upgrade to the MCU (Micro Processing Unit). This happens when updating to a higher version with newer microcode.

PHEW! It was a heart stopping 40 minutes.

 

By the way have you seen the RAVPower FileHub? It's a travel Router with wifi AC750 300Mbps Wi-Fi on 2.4Ghz or 433 Mbps on 5Ghz. It includes an SD Card Reader, 6700mAh Battery and can connect an SSD hd. Make this a portable NAS to store your pics and videos or upload your SD card pics/videos to a SSD hd. This is a bargain for under $60. (Amazon USA Link)
