WS-C3750-48P 12.2(25)SEB4 C3750-IPBASE-M
Hi,
All
Thanks in Advance
I need to add a third stackable WS-C3750-48P and i Already downgrade the new switch to existing ios on the new switch(12.2(25)SEB4 )
switch to an existing stack of 2 WS-C3750-48P ( 12.2(25)SEB4 ) and was wondering if the first 2 need to be powered down before I install the third?
and i already change the priority the existing master switch to priority 15
Do I need to configure the new switch with anything specifically? (aside from assigning ports, etc.)
I'm assuming since I'll have to move around the backend cable, there will be a traffic interruption?
do i need any other configuration to the new switch
now can i add the new switch to existing stackable switches , if i add the new switch then any changes will heppen
Regards
Syed,

Yes. It'll work.
You need to power down THE NEW stack member. Once you cable up only ONE of the stack cable, you apply power to the new member. Once this member has successfully joined the stack then you add the second stack cable.

New stack member must NOT have any configuration file or VLAN.DAT file.

now i have to put the new switch to existing switches , and there is no configuration on new switch and there is no VLAN.DAT file also i check
the existing switches are connected like this
1 Switch : port 2 : 2switch Port 2
only one
then do i have to remove stack cable and arrange it like
1 Switch : port 2 : 2nd Switch port 1
2 Switch : port 2 : 3rd Switch port 1
3 Switch : port 2 : 1st Switch port 1
or do some other
