Networking Gear for School

Ok, it is time to give serious thought to equipment as I get ready to upgrade my network but, I need also some help on design consideration. The  high school servers approx 350 users.

First - The school campus has three basic structures.

Bldg 1 has servers and Internet routers located in basement. One cable from this room goes to Bldg 3 and one cable goes upstairs to closet 1. (cable being Cat5)

Closet 1 serves- 20 classroom/office drops, A feed to Bldg2, and serves as a feed for the next closet in this building (Closet 2)

Closet 2 serves 20 drops and as a feed for Closet 3

Closet 3 is the endpoint and this also serves about 20 drops, a couple of which in labs, have multi-port switches.

Bldg 2 fed from Bldg1 Closet 1 serves a dozen or so drops.  One drop has a small switch to serve that lower level.

Bldg 3 fed from Bldg1 server closet serves 10 drop, once again one drop has a small 5 port switch serving a small cluster.

Server closet to Closet1 has two Cat5 runs a small fiber (single mode?)

Closet 1 to Bldg same as above.

Closet 1 to Closet 2 and Closet 2 to closet 3 have two Cat5 350 mhz certified in link aggregation for redundancy and bandwidth.

All of Bldg 1 Closets and Server Closet use either Cisco/LinkSys SRW2016, SRW2024, or SRW2048.  The other Bldgs use  Trendnet switches.

Besides the obvious of trying to upgrade cabling/links between closets, I need to think about equipment that can handle future PoE for AP's, potential VOIP, and bandwidth between hops.  Layer 3 for future static routing and definitely managed.

Thoughts and suggestions? Brocade, Cisco SG -300, Hp Procurve, Juniper?  Oh, we are a small non-profit so budget is always a concern.

I can only go with what we use at my current job in education. The HP 1920 Switch Series seems to be a good choice, depending on your budget. They have 8 / 16 / and 24 port versions that come with PoE and layer 3 switching with central management capabilities. You can use copper or upgrade to fiber for your switch to switch connections. In your main office you would be better off to get one 4000 series or 5000 series switch to connect all of your runs and possible route too. Or you can convert your 5000 series switch to act as an router as well.
