I have looked at the specs, and my recommendation as a LAN administrator
is that you choose a different model or different product. With
80 ports, I would strongly recommend using a managed switch instead
of an unmanaged switch. Managed switches make it MUCH easier to locate
errors in the network. If a guest is complaining that s/he is
having network problems, you don't want to be having to break out
the network test probe and go around to every wiring closet and monitor
for awhile -hoping- that the problem shows up. You want to instead be
actively monitoring the system for error reports and having monitoring
software that creates notifications (possibly pages) when there is
trouble on the network.
Looking at the specs of those two devices, it appears that one of them
has a module that can have two 100FX ports, which are used for fibre
optic connections to remote switches or routers. Fibre connections are
required if the switches are too far apart (more than 100 metres.)
The limit for 100FX is 2 km with regular multimode fibre. Built-in
fibre ports is not strictly required, as you can use a regular ethernet
port together with a "media convertor" -- but decent 100 Mbit/s media
convertors cost a few hundred dollars per pair.
Only one of those two DLink devices quotes any performance specification
that I could find: it says has a 4.3 Gbps backplane. The speed of
the other one is not rated. 4.3 Gbps is comparable to Nortel's
respected Baystack 470 [managed] switch, but is about half of Cisco's
(noticably more expensive) 3550 multilayer switch.
The fact that you are considering unmanaged switches for this project
suggests to me that you have not had an experienced LAN administrator
review the details. I would suggest to you that bringing in a
consultant to look over your proposed plans would be well worth the
money in the long run.
