Design Recommendations

I’ve recently inherited a small-ish business that has two Cisco 3750 series stacks, two switches per stack. Just a single flat /24 network and a DMZ.

One stack of 3750x wall mounted that all of the forward facing devices connect to voip phones, Laptops, desktops, credit card machines, TVs, etc. this stack also provides POE.

The other stack of 3750g is setup in the rack providing bonded (2x 1G) connections to all the servers and other rack mounted devices, voip stuff, san (separate physical switch) router, firewall, isp gear etc…

There’s also a bond between the two stacks. (2x 1Gig)

1. Any recommendations on core design changes? I don’t have too much experience with stacked Cisco gear but it seems pretty solid.

2. Each cube has two network cable drops, originally planned for one voip device and one workstation. Things have changed a bit and now there’s a few locations with a need for 4+ connections (Credit card terminals, docking stations, phone, desktop, etc). The not so technical folks have installed random dlink cheap switches to remedy this. I’m planning to replace these as running new cable drops is not an option at the moment. POE, 8ish ports are the only requirement. I’ll probably stick to Cisco gear as well from a consistently stand point. Any recommendations?

Overall everything is working pretty well. No issues. I’m mostly just curious on others opinions of the setup. :)

Thanks!
