Cisco 4331 Integrated Services Router

Sourcing mission-critical hardware shouldn't mean gambling on auction sites or automated shopping carts. You get direct access to dedicated specialists who answer the phone, confirm exact compatibility, and deliver project-ready pricing built around your deployment timeline.

The Cisco 4331 ISR sits in the 4300 Series of the Cisco 4000 Family and is ordered as ISR4331/K9. It is a 1 RU router with three onboard 10/100/1000 Gigabit Ethernet ports, two NIM slots, one SM-X service-module slot and one ISC slot. A second order code, ISR4331-DC/K9, is the DC model, which takes 24 to 60 V DC input, and PoE-based modules cannot be used once a DC supply is installed. The 4331 includes 19-inch rack-mount brackets and supports wall mounting. Cisco also sells it as the ISR4331-SEC/K9, ISR4331-V/K9, ISR4331-VSEC/K9, ISR4331-AX/K9 and ISR4331-AXV/K9 bundles.

Memory sits in two DIMM sockets. The default 4 GB is two 2 GB DIMMs, and an upgrade must fill both sockets with DIMMs of the same type and density, as Cisco does not support mixed densities or a single DIMM. MEM-4300-4GU8G takes the router to 8 GB, and MEM-4300-4GU16G reaches the 16 GB maximum. Flash starts at 4 GB and reaches 16 GB through MEM-FLSH-4U8G and MEM-FLSH-4U16G. The motherboard has an mSATA connector for an SSD-MSATA-200G drive. Connections are one USB 2.0 Type A port, a USB mini console port, and RJ-45 console and auxiliary ports.

The SM-X slot takes service modules, and an SM-X-NIM-ADPTR adapter turns it into a NIM slot. Each NIM slot offers up to two 2 Gbps connections, and the NIM-ES2-4 and NIM-ES2-8 Gigabit Ethernet switch modules fit up to two per router. The ISC slot holds a PVDM4 voice DSP module, and the ISR4331-V/K9 and ISR4331-VSEC/K9 bundles come with a PVDM4-32. Aggregate throughput is 100 Mbps by default, and the FL-4330-PERF-K9 performance license raises it to 300 Mbps.

Cisco IOS XE runs from one universal image with IP Base active by default. The SL-4330-SEC-K9, SL-4330-UC-K9 and SL-4330-APP-K9 packages switch on by license, and FL-4330-HSEC-K9 provides full crypto functionality. The AC power supply sits inside the chassis and takes 100 to 240 V AC. PWR-4330-AC is the default part, and PWR-4330-POE-AC is the PoE model. There is no redundant power option.
