Please forgive the upcoming daft question but I need to ask it as I don't know the answer :)
I've been reading peoples posts on this site singing the praises of managed switches, particully the HP Procurve series. At the moment all of the switches on our network are unmanaged with the odd "Smart" switch thrown in for good measure (Example, Netgear Prosafe FS726T). Would benefit is there to be had to going over to managed switches? According to my calculations replacing them all with a mixture of Procurve 2848, 2626 and 2650 would cost about £5200 (still less than one Cisco 48port gigabit managed switch!). Is it worth the money? How would I sell the proposition to my line manager (A non technical assistant head)?
