The story,
the network engineer resign, I am the new guy with normal home network knowledge, as I am not applying the network engineer position, but somehow I got his task: replacing the switch.
the site contain the network equipment can only visit once per month.
I have not yet visit the site, and the last network engineer did not left any "network diagram", and I hear the wiring to both switch already disconnected, so I have no idea the wiring to the switch.
Need help on figure out the network diagram.
the only thing I know, hear from the guard that was watching the last network engineer work:
1. two switch in that site, I hear it is for redundancy, one of them broken, one of them is good, and the good one is in my hand, and I have access to its config.
2. the two switch model are WS-C2960-8TC-S, I hear they have different IP.
3 there is two firewall, I don't know the model.
4. might be two ISP cable connect to the internet, or might be just one, not sure.
5. one server, I assume it has two NIC port.
6. I hear the "SFP Modules" in the switch might be used.
7. the config of the good switch

got this disconnected photo from the guard
seems simple, right? for each switch
so the purpose of the switch is convert the fiber signal to RJ45?
there is no fail over ? or am I missing something?

as per the information switch action as Layer 2 switch, but the failed switch is part of stack may be ?
can you check from working switch, show switch ( post output here)
we are also same like your guess, based on the cables ?
where is this yellow cable going ? to other switch ? what port they connected ?

I already show the working switch config in my first post.
the yellow cable is the fiber cable, I guess it is to the switch.

Pay more attention what we asked for - show switch ( post output here)
The yellow cable is the fiber cable, I guess it is to the switch. - if you sure please carry on test it..what are you waiting for ?
