& Benefits of Migrating to Cisco 4000 Series
We talked about the ISR 4000 Series a lot before, such as the Cisco 4000

vs. 3925 Router.
In this article, we will continue to say something about the modular
routers-Cisco 4000 Series ISRs.
The Cisco 4000 Series ISRs are modular routers with LAN and WAN
connections that can be configured by means of interface modules, including
Cisco Enhanced Service Modules (SM-Xs), and Network Interface Modules
(NIMs).
Cisco 4000 Series ISRs introduce new chassis, modules, and WAN services
with a robust management framework and validated designs for the Cisco
Intelligent WAN.
Cisco 4000 platforms, together with Cisco UCS E-Series server modules,
provide a flexible platform that can easily adapt to the changing application
landscape. Use these routers to support all cloud applications on any device.
Cisco 4000 Series ISRs are designed to meet Gigabit forwarding performance
needs while running the broadest set of network and application services on a
single platform.
Cisco 4000 Series ISRs offer:
 High-quality user experience: During peak loads, the multi-core
CPU architecture running Cisco IOS-XE can enable resiliency by using
separate control and data services planes.
 Faster response to business and user needs: New pay-as-grow
performance and services allows IT increase throughput and expand
across a rich portfolio of on-demand network and application services
with no truck rolls
 A wide range of connectivity options: ISR 4000 supports
integrated Gigabit Ethernet, T1/E1, T3/E3, PRI, xDSL, and more
 Unified communications: Get comprehensive edge support for
session border control, branch telephony survivability, TDM gateways,
and more.

2. The Cisco 4000 Series Simplifies:
 Operations and management
Get IT automation for configuration, monitoring, and management
through theCisco Application Policy Infrastructure Controller
(APIC) Enterprise Module and an open ecosystem of partners.
 Branch infrastructure
Reduce branch footprint and power consumption with an all-in-one
platform that brings together network, compute, and storage.
Customers can choose optional integrated compute and storage with
Cisco UCS E-Series Servers for hosting applications and services.
 Meeting unplanned business requirements
Deploying 4000 Series ISRs allows you to expand and pay for products
only as your needs grow. Customers can standardize on a single

3. platform and add services and capacity without disruptions or truck
rolls.

Compare the Various Models of Cisco ISR 4000 Series Platform
Cisco ISR 4000 Platform Comparison
The Cisco 4000 family contains the Cisco 4451, 4431, 4351, 4331,
and 4321 routers, which differ primarily in performance capabilities and in
the number of Network Interface Module (NIM) and Enhanced Service Module
(SM-X) slots supported.

5. The Cisco 4000 Family contains five platforms: the 4451, 4431, 4351,
4331, and 4321 ISRs.
You can order Cisco 4000 Series ISR platforms with dual power supplies that
may be configured for power-supply redundancy or increased power for
Power over Ethernet (PoE). The primary and secondary power supplies can be
AC, PoE, DC, or any combination of the three. In order to power PoE ports on
a switch module integrated into a router, you must order the router with a
PoE power supply.
You can order the power supplies listed in the Figure above with the system
or as spares.The PoE power supply on the Cisco 4000 Series ISRs requires a
C15-rated power cable to accommodate the higher current rating of these
power supplies.
Cisco 4400 Series ISRs (models 4451 and 4431) ship with a default
memory of 2 GB of DRAM for the data plane, 4 GB of DRAM for the control
plane, and 8 GB of flash memory. The 4 GB DRAM configuration for the
control plane is derived by the installation of two symmetrical dual in-line
memory modules (DIMMs) of 2 GB in each of the memory slots.
The Cisco 4300 Series ISRs (4351, 4331, and 4321) ship with a default
memory of 4 GB of DRAM for both the control plane and data plane and 4 GB
of flash memory. In the 4351 and 4331, the 4-GB DRAM configuration is
derived by the installation of two symmetrical DIMMs of 2 GB in each of the
memory slots of the Cisco 4351 and 4331 ISR platforms. In the Cisco 4321
ISR, 4 GB of DRAM is soldered on to the motherboard and is not serviceable.
When upgrading memory to higher densities, both memory slots must be
populated with DIMMs of the same type and density for high system
performance.
The Cisco 4000 Series platform does not support the use of different DRAM
densities in the two available DIMM slots or the use of only one slot.
Cisco 4400 ISRs ship with 8 GB of flash memory by default. Cisco
4300 Series ISRs ship with a default 4 GB of flash memory, which is soldered
on the motherboard and is not serviceable. On Cisco 4300 Series ISRs,
installing an additional flash memory module will disable the onboard flash
memory.
Each Cisco 4000 Series ISR ships with a default accessory kit
consisting of:
● 19-inch rack-mount brackets

6. ● Regulatory and Compliance Safety Information (RCSI) guide
The default accessory kit does not include any Category 5 RJ-45 Ethernet
cables or cables for the router console or auxiliary port. You can order the
console and auxiliary cables as an option during router configuration or as
spares.
You may order the 23-inch rack-mount brackets, blank faceplates for module
slots, and slot dividers as spares.
Opacity shields are not required for the Cisco 4000 product family, as the
router ships with a solid cover and the router interior is not exposed. Table 9
lists the part numbers for cables, rack-mount brackets, blank faceplates, and
storage drives
Cisco ISRs deliver innovative technologies running on the industry-leading
Cisco IOS Software network operating system.
The Cisco 4000 Series ISR family ships with a universal Cisco IOS Software
image that contains all the features available for use on the router. A specific
feature set is activated by using technology package licenses, such as
Security, Unified Communications, and Application Experience licenses.
Cisco 4000 Series ISRs support two types of universal images:
● Universal images with universalk9 in the image name: This universal
image offers all the Cisco IOS Software features, including strong payload
cryptography features such as IP Security VPN (IPsec VPN) and Secure
Unified Communications.
● Universal images with universalk9_npe in the image name: The strong
control of encryption capabilities by Cisco Software Activation helps meet U.S.
export control requirements for cryptography. However, some countries have
import requirements that require that the platform not support any strong
payload cryptography. To satisfy the import requirements of those countries,
Cisco allows you to order the router with an Non-Payload Encryption ("NPE")
universal image. The NPE image does support security features such as zone-
based firewall and intrusion prevention through the SECNPE-K9 license.
