I have a network I do not expect to exceed 750 devices. Would the 4507 be appropriate for that number of devices. 10 closets will feed back via fiber, all in differnet vlans, to access email/file servers/proprietary programs on a separate vlan. Collapsed core design would be in use. Just wondering if anyone else has used the 4500 series switch at the distribution/core layer with that number of devices connected.
