J-series Services Router Hardware
Features
J-series Services Routers running JUNOS software with enhanced services have chassis
that are similar but with important differences. J2320, J2350, and J4350 routers have
a single nonredundant power supply and an optional Crypto Accelerator Module.
J6350 routers have redundant power supplies and a standard Crypto Accelerator
Module.
For field-replaceable PIMs, the J2320 has three slots, the J2350 has five slots, and
the J4350 and J6350 have six slots. Of the six slots, two on the J4350 and four on
the J6350 are enhanced (high-speed) slots.
All J-series routers run JUNOS software with enhanced services, which offers advanced
routing and security features.
