J2320 Services Router Overview

The J2320 Services Router is primarily designed for remote or branch offices. It has a small chassis that is 1 U (rack unit) in size with a nonredundant AC power supply, an external compact flash and two universal serial bus (USB) ports for external storage, and an optional Crypto Accelerator Module.

J2320 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. The memory on J2320 routers can be upgraded to 1 GB. For instructions on upgrading memory, see Replacing DRAM Modules.

Each J2320 chassis contains four built-in Gigabit Ethernet ports with link speeds of 10/100/1000 Mbps over a copper interface. The chassis also contains three slots for field-replaceable Physical Interface Modules (PIMs) and Avaya voice over IP (VoIP) modules providing flexible WAN and voice connectivity options.
