Why do Cisco state that they must be part of the same data stack then?
I have since found this in an old 3750-X document: -
Do not configure power stacks that span across data stacks.
Cisco StackPower is limited to four switches per power stack although one stack of nine switches can be configured over multiple power stacks; this is a supported deployment. On the other hand, one power stack can also span over multiple data stacks although it is not recommended. It is not a recommended deployment because of display and control reasons. That is, StackPower reports the power budget, priorities, neighbor information, and similar parameters to the stack master; therefore having two stack masters would make management a nightmare. In this scenario, there would be two masters receiving information about the same power stack, that would confuse the administrator and would cause unexpected behavior in case of load sheds.

Thanks Jaderson
I looked through the link and actually found the following statement: -
Switches in a power stack must be members of the same switch (data) stack.
So it does look like you can't have StackPower spanning 2 different data stacks.
I now need to find a calculator to size the number of power supplies required across the stack.

Hi, just got a couple of questions regarding StackPower and StackWise on the 3850.
Is it possible to use StackPower between switches that are not stacked using StackWise?
If I have a stack of 4 switches and are looking to configure StackPower mode redundant, is there a calculator to work out how many power supplies I need to install across the 4 switches, with x number of PoE ports?
Thanks in advance for any assistance.

Hi,
Previously we have used the 3602 for P2P bridges in autonomous mode, does the 3802 support the same Bridging capabilities?
thanks.
Paul.

Thanks for the reply. The 2960XR are connecting to the backbone, which uses OSPF and also down to the 2960X access layer switches. The devices will be WAPs and end user hosts.

Hello, We are looking at putting together a solution using dual stacked 2960XR switches, which are linked to the core. The 2960XR will be running OSPF for routed access and we have been asked to provide some figures for the performance of the switch when routing, e.g. Packet processing and packet forwarding rates. Latency. Maximum and minimum delays for packet transition through the device. Are we correct to state that the routing is carried in ASICS and therefore it is at wire speed, where does CEF come into it? Many thanks for any guidance you can provide. Paul

Thanks Adawa, Looking at the comparison I believe the 1530 will do nicely, unless you have some concerns. Do you have a table detailing the minimum supported WLC software version for the APs. Paul.

Hi Rasika, Thanks for the quick and informative response, much appreciated. Due to the harsh environment the cranes work in we were thinking of installing the 1530 AP with an external directly antenna at each end of the warehouse and at the crane end use the 1530 with internal antenna. Can you see any issues with using this product or would you consider another AP? thanks again Paul

Hello We are looking at a point to multipoint solution for providing data connectivity to cranes in a large warehouse. The cranes operate on static rails so they can only move in a set pattern. The plan is to install a root bridge at 1 end of the warehouse with a directional antenna providing wireless for the cranes. Each crane will have a non-root bridge installed on the outside and an RJ-45 cable linking to the device on the inside. To provide additional network coverage at the opposite end of the warehouse is it possible to install a second root bridge. If so would the cranes automatically associate with either root bridge as they move along the crane track? Hope this makes sense and thanks in advance for any guidance. Paul
