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.
