J2320 and J2350 Services Router Hardware Features

J-series J2320, J2350, J4350, and J6350 Services Routers 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 and Avaya VoIP modules, 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 the JUNOS Internet software.
