this project was not involved for me at first.
but my co-worker couldn’t configure Firewall, so i went to FSC and i surprised because of rack installation and configuration on switch and router.
the devices on rack were installed without empty space. it could cause problem by heat even though the server room not warm.
there were 3560 2ea and 2960 4ea. but, my co-worker just configured them as L2 switch and redundancy was not considered.
so i had them reconnected between between devices and i reconfigured them.
all people have their own view. but at least as network engineer, we need to discuss our regular design.
