2960G fiber to fiber redundancy

Hi, we are moving offices soon.
The entire office is wired up with CAT6 cabling. We are looking at converting one of the offices into a server room.There is a network rack in the open office area where all the network points terminate.

I am planning on patching them into two 24 port 2960g's and using 2 fiber uplinks to connect them to a second pair of 2960g's. I will use one of their four dual purpose ports for GBIC fibre connectivy. The other three will be used as trunk ports between each pair of switches. What I would like to know is how would I connect the fiber links across so that they are completely redundant on each end and what would be the best way to configure the trunk ports between each pair?

Hi,

To link the pair of switches, an etherchannel with the number of interface desired (3,4,..) can be done using the "ports" too as you are using 2960G's.
For the link between the stacks, the solution you proposed covers you for a switch failure but the spanning tree will block one of the fiber ports.
An other option might be to use 2 fiber ports from the same switch and etherchannel them. You''ll get 2Gb/s but will loose the switch failure coverage.
It all depends on your applications and traffic pattern.
I hope that helps

Thanks,

Would the same be possible using the following setup as well?

Two  2960G-48-TT-L using fiber converters on the uplink ports conecting to two WS-C2960-24TC-L gbic fiber ports. Using any of the other interfaces on the 48 ports to stack?

It will depends on your mix.
If you need to 48 ports at one place and the 24 at an other, as the 24 are only 2960 you will not be able to do the etherchannel with Gb ports between the switches.
You are then back to your initial config with the spanning tree blocking one of the Gb link (you may want to change the stp cost so it is not the uplink between the switches that is blocked).

Ok so I will definitely go with 4 Ws-C2960-24TC-L's then. But how will I be able to cater for both switch redunancy and dual uplinks?
