Hardware Requirements for Cisco 9200 Stack wise.

[Zee-Far-Man]

Good day Pros,

I got a task from my Management to Refresh/Replace existing old switches to new Cisco Catalyst 9200 Stack wise.

I need to know about the Hardware requirement for Stack wise.

1.   How many power supply for each switch?

2.  Do I need only one OR Two fans for each switch?

3. Does Stack cable comes with the switch? and most important What 9200 switch model works for Stack Wise.

Thanks in advanced.

Zeeman.

 You need to buy stack  kit. 

About power supply you need to know what this switches will be used for. Example, if they will supply PoE for Access Points or cameras, they will need two power supply but if they will server only PCs, you can use one power supply. The same goes for FAN.

The restriction for stacking is below.

Restrictions for Switch Stacks

The following are the restrictions for switch stack configuration:

• A switch stack can have up to eight stacking-capable switches connected through their StackWise ports.

• Only homogenous stacking is supported, that is, a stack of Cisco Catalyst 9200 Series Switches with only Cisco Catalyst 9200 Series Switches as stack members.

• You cannot have a switch stack containing a mix of different license levels.

• Do not stack Cisco Catalyst 9200L Series Switches with Cisco Catalyst 9200 Series Switches.

• C9200-24PB and C9200-48PB switch models can only be stacked with each other and not with other models of the Cisco Catalyst 9200 Series Switches.

• During a switchover, when the standby device syncs with the active device, the following log message is displayed on the console:

  %SM-4-BADEVENT: Event 'standby_phy_link_up' is invalid for 
  the current state 'NO_NEIGHBOR': rep_lsl_rx Gix/x/x -Traceback=

  Ignore this message. It does not have any functional or operational impact.

@ Flavio Miranda,

Much appreciated. Need one more expert advice, what if we buy C9300-48UN. I could not find the specification/difference between 9000 and 9300 switches.  You are the expert could you tell what is the big difference.

Thanks.

This is just a spoiller , you can check all the details on the link above. You can also compare the different models of 9200 and 9300
