Replacing Stacked 24 port 2960s with 48 port

[Jacob Berger]

same  IOS version

WS-C2960S-24PS-L

for

WS-C2960S-48LPS-L

Whats the best way to do this without powering down the stack.

thanks

• Do not apply power to the new stack member. 
• Connect the stack cables. 
• Power up the new stack members.

will the stack detect the 48 port switch and allow me to config all its ports or will it still remember only 24 ports ?

[Leo Laohoo]

Let us presume that your 24-port is switch 3 in the stack.  So you can remove the configuration of the 24 port by using this command: 

config t

no switch 3 provision WS-C2960S-24PS

switch 3 provision WS-C2960S-48LPS

<You can start configuring your ports EVEN BEFORE you connect the 48-port switch to your stack>

end

Thanks

the stack contains 3 switches

could i provison the new switch as number 4 and config the ports

then remove switch 3 and convert switch 4 to number 3?

If you use your method, there will be MORE disruption to clients connected to switch 3 because you need to reboot switch 4/3 TWICE. 

With my method, your disruption is minimized to just ONE disruption.  

Your choice.

OK

but i gain time configing the ports before (multiple vlans)

as you say ... my choice

thanks
