Cisco 4000 Series ISRs provide you with Cisco Intelligent WAN
(IWAN) software features and a converged branch infrastructure.
Along with superior throughput, these capabilities form the
building blocks of next-generation branch-office WAN solutions.
Cisco ISR 4321 features modular network interfaces with diverse
connection options for load-balancing and network resiliency and
modular interfaces with online removal and insertion (OIR) for
module upgrades without network disruption.

Table below shows Cisco 4000 Series ISR General Feature Highlights
Architectural Features | Benefits/Description |
Multicore processors | ● High-performance multicore processors support high-speed WAN
connections. The data plane uses an emulated Flow Processor (FP)
that delivers application-specific integrated circuit (ASIC)-like
performance that does not degrade as services are added. |
Embedded IP Security (IPsec) VPN hardware acceleration | ● Increases scalability. When combined with an optional Cisco IOS
XE Software Security license, enables WAN link security and VPN
services. |
Integrated Gigabit Ethernet ports | ● The Cisco 4000 Series provides up to four built-in 10/100/1000
Ethernet ports for WAN or LAN. ● Based on the platform, some of the 10/100/1000 Ethernet ports can
support Small Form-Factor Pluggable (SFP)-based connectivity in
addition to RJ-45 connections, enabling fiber or copper
connectivity. ● Optionally, depending on the platform, up to 30W PoE+ can be
enabled on two of the built-in front panel Gigabit Ethernet
interfaces to provide power to external devices such as
fourth-generation (4G) LTE routers. ● An additional dedicated Gigabit Ethernet port is provided for
device management. |
USB-based console access | ● A mini type B USB console port1 supports management connectivity
when traditional serial ports are not available. ● Traditional console and auxiliary ports are also available. |
Optional integrated power supply for distribution of PoE | ● An optional upgrade to the internal power supply provides inline
power (802.3af-compliant PoE or 802.3at-compliant PoE+) to optional
integrated switch modules. ● Redundant PoE conversion modules provide an additional layer of
fault tolerance. |
Optional integrated redundant power supply (RPS) | ● For the 4400 Series, power redundancy is available by installing
an optional integrated RPS for decreasing network downtime and
protecting the network from power failures. ● Optional PoE boost mode increases total PoE capacity to up to
1000W. |
Cisco Enhanced Services Module (SM-X) | ● Each service-module slot offers high data-throughput capabilityof
up to 10 Gbps toward the system and up to 1 Gbps to other module
slots. ● Support for both single- and double-wide service modules provides
flexibility in deployment options. ● An SM-X slot can be converted into a Network Interface Module
(NIM) slot using an optional carrier card. ● Service modules support online insertion and removal (OIR),
avoiding network disruption when installing new or replacement
modules. |
Cisco Network Interface Modules (NIMs) | ● Up to three integrated NIM slots on the Cisco 4000 Series allow
for flexible configurations. ● Each NIM slot offers options of up to two 2-Gbps connections, one
toward the route processor and one for direct module-to-module
communication. The 4221 ISR has only one 1-Gbps connection to the
route processor. ● NIMs support OIR. ● Special NIMs add support for solid-state drives (SSDs) and hard
disk drives (HDDs). |
Cisco Integrated Services Card (ISC) slot on motherboard | ● Integrated Services Card natively supports the new Cisco
High-Density Packet Voice Digital Signal Processor Modules
(PVDM4s), providing greater-density rich-media voice. ● Each Integrated Services Card slot connects to the system
architecture through an up to 2-Gbps link. ● Future modules can be hosted on the Integrated Services Card
slot, improving system functions. |
Flash memory support | ● A single flash memory slot is available to support high-speed
storage densities, upgradable to up to 32 GB. The 4221 ISR ships with a fixed 8 GB flash. ● Two USB type A 2.0 ports provide capabilities for convenient
storage. |
DRAM | ● For the 4400 Series ISRs, the default control-plane memory is 4
GB, upgradable to 16 GB to provide additional scalability for
control-plane features. The default data-plane memory is 2 GB. ● For the 4300 Series ISRs, the default memory is 4 GB, upgradable
to 16 GB (only 8 GB for the 4321) to provide additional
scalability. ● The 4200 Series comes with 4 GB fixed DRAM. |
