J4350 Services Router Overview
The J4350 Services Router is designed primarily for regional and branch offices. It
has a chassis that is 2 U (rack units) in size with a nonredundant AC or DC power
supply, and a universal serial bus (USB) port for external storage.
J4350 routers ordered with the optional Crypto Accelerator Module come standard
with 1 GB of memory, while those ordered without the Crypto Accelerator Module
come standard with 256 MB of memory. J4350 routers can contain between 256
MB and 2 GB of memory. For instructions on adding memory, see "Replacing DRAM
Modules" on page 136.
Each J4350 chassis contains four built-in Gigabit Ethernet ports with link speeds of
10/100/1000 Mbps over a copper interface, and six slots for field-replaceable Physical
Interface Modules (PIMs). Two of the six slots (slots 3 and 6) support high-speed
interfaces (ePIMs).
