How to insert 450-24t into operational stack of 450-24ts?

[ac1dh3ad]

Hi all,
Tried to find out answers in existing threads, but with no results.
There is an operational stack with 450-24Ts and i need to insert another 450-24T into existing stack. I suppose to implement following steps,
1. Check software, firmware and isvn of new switch to meet software requirements of an operational stack (i guess identical isvn is enough).
If software requirements are met, continue, otherwise update software.
2. Turn off new switch and turn unit select switch off (down) (as base unit is already running)
3. Connect out and in cascade cables to new switch while stack is running(Is it really possible?)
4. Turn up new switch and upon bootup switch will be automatically within a stack and have all configuration done.

Here are some question worrying me,
Is it really enough to have identical isvn when dealing with same model?
Is it possible to insert new switch into stack while stack is running?
Is there any additional configuration must be done on the operational stack?
And am i missing something?

Many thanks.

No identical ISVN is only for hybrid stacks (450, BPS2000) if a pure stack of 450's all need to run the same sw and fw.

No the 450's don't support inserting into a new stack. You will have to power down the stack, cable in the new switch then power up the stack.

You should make sure you insert it at the opposite end of the stack to the base. If you add it into the middle it's possible to corrupt the config.

Once the stack has come up make sure the switch has numbered itself, then you can configure it.
