I have a Juniper Networks SPP5100SR-J3
740-021308 REV 01 10GE SFP+SR
that has stopped working, are these devices warrantied from Juniper.?
Or just trash it and buy another.?
There is a one year warranty and as I understand it, they are also covered via the switch/routers support contract.
Check warranty status via https://entitlementsearch.juniper.net/entitlementsearch/welcome.do - or ask JTAC to RMA if the Juniper equipment is covered under active support.
