recommended firmware

    WS-C2950T-24 ==> IOS 12.1(22)EA12

see if it is eligible for a Standard (SI) or an Enhanced Image (EI) here

the firmware are no longer available from Cisco. there is not even a page for it (there is only one about LRE - Long Range Ethernet)

the latest firmware for our device seems to be 12.1.22-EA14 from Nov 2010

there has been mentions of 12.1(22)EA15 from Cisco but that version has never been available, and probably has never truly existed, as the product was already EOL
