J4350 Services Router Overview

The J4350 Services Router is designed primarily for regional or 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 190.

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) and Avaya VoIP modules. Two of the six slots (slots 3 and 6) support high-speed interfaces (ePIMs).

The J4350 Services Router supports the following field-replaceable PIMs and Avaya VoIP modules:
