The system is using a non-recommended boot mode – Cisco 3650 iOS-XE Upgrade

**Objective of this documentation: Correcting the “The system is using a non-recommended boot mode” message when upgrading Cisco 3650 software.**

Topology: I’ve a PC (which is my TFTP server and where the latest iOS-XE is located. IP: connected to my 3650’s GigabitEthernet1/0/2. The 3650 is then connected via GigabitEthernet1/0/48 to the network switch, 2960 (whose IP is Port connected is FastEthernet0/13)

**Problem 1: VLAN Mismatch Error or remote port shutdown**

g1/0/2 is connected to the wrong VLAN. f0/13 is connected to VLAN 1.

switch> en
switch# config t
switch (config)# int g1/0/2
switch (config-if)# sw access vlan 1
switch (config-if)# end

Also make sure than g1/0/48 is connnected to VLAN 1. (Otherwise, repeat above steps)

**Problem 2: Cannot ping tftp server on PC**

VLAN 1 is not set with an IP address.

switch> en
switch# config t
switch (config)# int vlan 1
switch (config-if)# ip address
switch (config-if)# end

Now you should be able to ping the PC/TFTP server, hence proceed with Upgrade:

switch#copy tftp flash
Address or name of remote host []?
Source filename []? cat3k_caa-universalk9.SPA.03.03.05.SE.150-1.EZ5.bin
Destination filename [cat3k_caa-universalk9.SPA.03.03.05.SE.150-1.EZ5.bin]? <Enter>

*(this process may take a longer time, since the image is ~250MB)*

When done, verify the downloaded file

switch#verify flash:cat3k_caa-universalk9.SPA.03.03.05.SE.150-1.EZ5.bin

Usually at this point, you would just:

switch#config t
switch(config)#boot system flash:cat3k_caa-universalk9.SPA.03.03.05.SE.150-1.EZ5.bin

**BUT** doing so may cause the error:

The System is using a non-recommended Boot mode.
Not all features may be available in this boot mode.
Please check the product configuration guide.

Check 3650 to see if package is expanded:
