Replacing Faulty Switch on Stack

Replacing Faulty Switch on Stack

Hi Friends,
i would like to provide you simple and easy method to replace the faulty switch on Stack without restarting all the switch.


Step 1: logging to stack switch ( Only Master switch accessible), and issue the command show switch

Switch#show switch
Switch/Stack Mac Address : 0000.0001.0001   
                                           H/W   Current
Switch#  Role   Mac Address     Priority Version  State
----------------------------------------------------------
*1       Master 0000.0001.0001    15     0       Ready              
 2       Member 0000.0001.0002     10     0       Ready              
 3       Member 0000.0001.0003     5      0       Ready              
 4       Member 0000.0001.0004     4      0       Ready

Please ensure priority must be high for Master switch. By default, all the switch will have priority 1.

Step 2 : Identity the switch to be replaced

Step 3 : unpack the new Switch , identify model and IOS version must be same replaced switch on that slot.

Step 4 : Note the stack port cable ( backside of the switch) must be connected to same port was connected.

Step 5:  power off faulty switch . this example assume Switch 4 is faulty. login to master switch , Type same command # show switch

Switch#show switch
Switch/Stack Mac Address : 0000.0001.0001   
                                           H/W   Current
Switch#  Role   Mac Address     Priority Version  State
----------------------------------------------------------
*1       Master 0000.0001.0001    15     0       Ready              
 2       Member 0000.0001.0002     10     0       Ready              
 3       Member 0000.0001.0003     5      0       Ready              
 4       Member 0000.0001.0004     4      0       removed

Step 6 : replace the faulty switch with new.

Step 7 : login to master switch , issue same command show switch
Switch#  Role   Mac Address     Priority Version  State
----------------------------------------------------------
*1       Master 0000.0001.0001    15     0       Ready              
 2       Member 0000.0001.0002     10     0       Ready              
 3       Member 0000.0001.0003     5      0       Ready              
 4       Member 0000.0001.0005    1     0       Ready

Switch priority will be shown as 1, it is best practice to change the priority to other value.

Switch#conf t
switch(conf)#switch 4 priority 4

switch has been successfully replaced
