I bought the cheapest Juniper EX3300 on EBAY [SETUP TROUBLESHOOT FIRMWARE FANMOD](HomeLab Pt6)

I purchased the cheapest listed Juniper EX3300-24p network switch on Ebay, and in this video go over power-on, trouble shooting, firmware update, with both the GUI and console CLI interfaces. In addition I fan mod the switch with Arctic 40mm fans to quiet it down for a home environment. This is a switch with 24 1-gigabit Ethernet network ports and 4 10 Gigabit SFP+ ports. This switch also has power over ethernet capability.
