CISCO 3750 Switch Stack
I have a below cisco 48 ports 3750 switch in branch office and would required to get more ports. Planning to buy one more switch. Existing switch run with below IPservevices SW image. I have below doubts
1. Do I need to purchase same 48 port switch to configure stack or can configure with one 24 and 48 ports together (Hardware need to be identical)?
2. IOS in new switch required to be same (C3750-IPSERVICESK9-M) or IPBASE will be fine (IOS need to be identical)?
Switch Ports Model SW Version SW Image

* 1 52 WS-C3750G-48PS 12.2(37)SE C3750-IPSERVICESK9-M

Alternatively, if i want to trunk between switches possible if new switch IOS is IPbase?

SW version can be different in both switches?

Thanks for chiming in InteraX. Looks like you are able mix and match IPBASE images along with IPSERVICE Images, with all of the SW Versions being the same.

This switch is going to be the core switch in branch office. Is there any restriction stack can't be configured on the core switch?.
There's no reason why the stack could be the core of a network. Even the IP base has routing protocol support.

Below I see in my current switch when I run sh switch and sh switch Neighbors. I believe its configured with Stack and ready to accept stack member switch. I have ordered 3750 24 ports switch with IP base IOS on it, and two stack cables. What exactly the next step to add member switch to this master stack switch?.
#sh switch

Hope this is the only command required in new switch before connecting
switch stack-member-number priority new-priority-value
switch stack-member-number priority new-priority-value

I have a doubt about Power stack. Does it also configure in master switch before plugging the stack cables and power on member switch?..

For both of your switches you will need to ensure they both run the same feature set of the IOS. So for the new switch you will be purchasing you will need to ensure it runs the IPSERVICE feature set.
