Overview of the Routers
Cisco
Integrated Services Routers Generation 2 (ISR G2) offer data
functionality through Gigabit Ethernet ports and security functionality
with a virtual private network (VPN) accelerator on the motherboard.
Additional security features are available with add-on hardware and
software.
Cisco 2900 series
and Cisco 3900 series routers also provide voice IP telephony with
digital signal processor (DSP) capability; and voice gateway, DSP farm,
IP-to-IP gateway, Cisco Unified Communications Manager Express (CUCME)
via Cisco IOS. Cisco Unity Express (CUE) is provided through the use of
add-on hardware.
This
series of ISRs have new slots that support next generation Enhanced
High-Speed WAN Interface Cards (EHWICs), Internal Services Modules
(ISMs), Packet Voice Data Modules (PVDM3s), Service Modules (SMs), and
Services Performance Engines (SPEs).
Access
to the Cisco Multi-Gigabit Fabric (MGF) facilitates connection between
switch ports on the ISR without utilizing all of the external ports. A
logical GE interface on the ISR connects external and internal modules
through the MGF for improved LAN and WAN switching.

Chassis Views
This
section contains views of the front and back panels of the
Cisco 2900 series and Cisco 3900 series routers, showing locations of
the power and signal interfaces, module slots, status indicators, and
chassis identification labels.
Note 
Routers
support the following slot types: Service Modules (SMs), Enhanced
High-Speed Interface Card (EHWICs), high-speed WAN interface cards
(HWICs), voice WAN interface cards (VWICs), WAN interface cards (WICs),
Internal Services Modules (ISMs), and packet voice DSP modules (PVDM3s).
However, some router models do not support all of these media types.
See the router model descriptions for more information.

Locating the Serial Number, PID, VID and CLEI
Software License
To
obtain a software license, you need a product authorization key (PAK)
and the unique device identifier (UDI) of the device where the license
will be installed.
The
serial number (SN), product ID (PID), version ID (VID), and Common
Language Equipment Identifier (CLEI) are printed on a label on the back
of the router or on a label tray located on the router chassis or
motherboard. The UDI can be viewed using the show license udi command
in privileged Exec mode in Cisco Internet Operating System (IOS)
software. For additional information on the UDI or how to obtain a PAK,
see the Cisco Software Activation on Integrated Services Routers document at Cisco.com.
The UDI has two main components:
•Product ID (PID)
Product ID (PID)
•Serial number (SN)
Serial number (SN)

For Additional Help Locating Labels on the Router
Use
the Cisco Product Identification (CPI) tool to find labels on the
router. It provides detailed illustrations and descriptions of where the
labels are located on Cisco products. It includes the following
features:
•A search option that allows browsing for models by using a tree-structured product hierarchy
A search option that allows browsing for models by using a tree-structured product hierarchy
•A search field on the final results page that makes it easier to look up multiple products
A search field on the final results page that makes it easier to look up multiple products
•End-of-sale products clearly identified in results lists

The
tool streamlines the process of locating serial number labels and
identifying products. Serial number information expedites the
entitlement process and is important for access to support services.

Gigabit Ethernet Ports
There are two different types of Gigabit Ethernet (GE) ports available on Cisco 2900 series and Cisco 3900 series ISRs.
GE Ports
The GE RJ-45 copper interface ports support 10BASE-T, 100BASE-TX, and 1000BASE-T.
SFP Ports
The
small-form-factor pluggable (SFP) ports support 1000BASE-LX/LH,
1000BASE-SX, 1000BASE-ZX, and Coarse Wavelength-Division Multiplexing
(CWDM-8) modules, as well as 100Mbs SFP modules.
The SFP port shares the same physical port as an RJ-45 GE port. Table 1-4 shows
the models that support SFP installation. The SFP port supports
auto-media-detection, auto-failover and remote fault indication (RFI),
as described in the IEEE 802.3ah specification.
Use the media-type {rj45{auto-failover}} | {sfp{auto-failover}} command to enable the auto-media-detection and auto-failover features. Use the Command Lookup Tool for details about this command.
The SFP port can be configured for the following behaviors:
The SFP port can be configured for the following behaviors:
•Always use the RJ-45 port.
Always use the RJ-45 port.
•Always use the SFP port.
Always use the SFP port.
•Always use the RJ-45 port but fail over to the SFP port if the RJ-45 port fails. This is the default configuration.
Always use the RJ-45 port but fail over to the SFP port if the RJ-45 port fails. This is the default configuration.
•Always use the SFP port but fail over to the RJ-45 port if the SFP port fails.
Always use the SFP port but fail over to the RJ-45 port if the SFP port fails.USB Serial Console Port
The
Mini-USB type B serial port has been enabled to perform management
tasks on the router. To use this port, you must install a Windows USB
device driver before establishing physical connectivity between a
personal computer and the router. See the "Installing the Cisco Microsoft Windows USB Device Driver" section for driver installation instructions.
Removable and Interchangeable Modules and Cards
Table 1-5 summarizes
the type of removable modules and cards that can be installed in the
router to provide specific capabilities. Services Performance Engines
(SPEs), Service Modules (SMs), and Enhanced High-Speed WAN Interface
Cards (EHWICs) fit into external slots and can be removed or replaced
without opening the chassis.
Internal
Services Modules (ISMs), expansion DRAM memory modules and
next-generation Packet Voice Data Modules (PVDM3s) plug into internal
connectors inside the chassis. These modules can be removed and
installed only by opening the chassis on the Cisco 3900 series, or
sliding the motherboard out of the Cisco 3900 series.
External Slots
Internal Slots
Because
of physical differences with the new slots, legacy network modules and
legacy Service Modules require an adapter for installation.

Services Performance Engine
Services
Performance Engines (SPEs) are modular motherboards for Cisco 3900
series ISRs. The SPE includes PVDM3 slots and system memory slots, and
the ISM slot. The Services Performance Engine provides a modular
approach to system upgrades. Slide out the SPE from the router to
replace internal modules, or to upgrade the SPE for improved router
performance.
See the "Removing and Replacing the Services Performance Engine" procedure for installation information.
Table 1-6 lists four SPE models that are supported on Cisco 3900 series routers. SPEs illustrations are shown in the "Chassis Views" section.
SPEs come preinstalled in 3900 series routers, or they are purchased
separately and installed in a 3900 series router. See the support table
for more information.

Service
Modules (SM) are the largest modules on Cisco 2900 series and
Cisco 3900 series ISRs. With the largest form-factor and power capacity,
these modules deliver high-performance service applications. SMs are
physically larger than legacy network modules, as a result, network
modules require an adapter for installation. See the Installing Cisco Network Modules in Cisco Access Routers guide for installation instructions,http://www.cisco.com/en/US/docs/routers/access/interfaces/nm/hardware/installation/guide/InstNetM.html.
Enhanced High-Speed WAN Interface Cards
Enhanced
High-Speed WAN Interface Card (EHWICs) are the latest generation of
interface cards. EHWICs are installed in the EHWIC slot on the router.
Legacy interface cards, such as WAN interface cards (WICs), voice
interface cards (VICs), high-speed WAN interface cards (HWICs),
double-width high-speed WAN interface cards (DHWICs), and (EHWICs) are
supported in the EHWIC slot on the router.
Services
Performance Engine 200 and Services Performance Engine 250 support the
following legacy interface cards in the EHWIC slots. (See Table 1-7.)
Table 1-7
EHWIC Support for SPE 200 and SPE 250
Integrated Service Modules
Internal
Services Modules (ISM) supersede advanced integration modules (AIM) on
Cisco 2900 series and Cisco 3900 series ISRs. The ISM is larger in size
than the AIM. Due to these physical differences, the AIM does not fit
into the ISM slot and is no longer supported on Cisco 2900 series and
Cisco 3900 series ISRs.
Packet Voice Data Modules
The
Packet Voice Data Modules (PVDM3s) are the latest generation of PVDMs.
First-generation PVDM-I cards are not supported in the PVDM3 slots. Due
to physical differences, PVDM2s require an adapter for installation in
the PVDM3 slot. See the "Installing and Removing PVDM2s" section for installation instructions.
Note PVDM2 cards cannot be mixed with PVDM3s.
PVDM2 cards cannot be mixed with PVDM3s.Memory
Cisco 2900 series and Cisco 3900 series routers contain the following types of memory:
•DRAM—Stores
the running configuration and routing tables and is used for packet
buffering by the network interfaces. Cisco IOS software executes from
DRAM memory. Supported module types are Unregistered Dual In-Line Memory
Module (UDIMM) and very low profile registered DIMM (VLP RDIMM).

Table 1-8 summarizes
the memory options for Cisco 2900 series and Cisco 3900 series routers.
Default memory represents the minimum usable RAM. You can install
additional RAM up to the maximum amount.
Expansion memory modules are UDIMMs or VLP RDIMMs with error correction code (ECC). All onboard RAM uses ECC.
Note The
current IOS supports only 2 GB of DRAM, although; the hardware supports
more. Future IOS versions may support more than 2 GB of DRAM.

Cisco 2900 series
and Cisco 3900 series ISRs support a variety of power supply
configurations. All power supplies are field replaceable and externally
accessible with the exception of the Cisco 2901 ISR. The Cisco 2901 ISR
has an internal power supply, which requires removing the cover for
replacement.
If
configured with dual power supplies or an Redundant power supplies
(RPS), the power supplies are hot swappable. RPSs require an RPS
adapter. There are two versions of the RPS adapter, one for the Cisco
2911 and one for the Cisco 2921 and 2951. Both use the Cisco Redundant
Power System 2300.
Configurations include AC and DC (with and without IP), Dual DC, internal POE, and POE boost.

Module and Router Power Consumption
Cisco
2900 series and Cisco 3900 series ISRs have energy efficiency features
that reduce power consumption. Some of the energy efficiency features
are controlled by the hardware, whereas other energy efficiency features
are controlled by the software.
Hardware Features
•High-efficiency AC power supplies.

The
Cisco 2911 and Cisco 3900 series ISRs have optional fan filters that
are easy to replace. The filters may be used to meet Network Equipment
Building Systems (NEBS) requirements, or to operate in dusty
environments. When a filter becomes dirty, discard it and replace it
with a new one. See the "Replacing a Fan Tray or Air Filter" section.
Fan
speeds are controlled by the fan speed controller circuitry. To
minimize noise, the fans operate at one of several predetermined speeds
and are dependent on the input ambient air temperature.

Real-Time Clock
Upon
system power up, the internal real-time clock with battery backup
provides the system software with the time of day. This allows the
system to verify the validity of the certification authority (CA)
certificate. The Cisco 2900 and Cisco 3900 series routers have a lithium
battery. This battery lasts for the life time of the router under the
operating environmental conditions specified for the router and is not
field-replaceable.
Note If the lithium battery in a Cisco 2900 or Cisco 3900 series ISR should fail, the router must be returned to Cisco for repair.
If the lithium battery in a Cisco 2900 or Cisco 3900 series ISR should fail, the router must be returned to Cisco for repair.
Although the battery is not intended to be field-replaceable, the following warning must be heeded:
Secure Key
A
hardware secure key storage unit is provided on the Cisco 3925 and
Cisco 3945 routers to safely store passwords and credentials. The secure
key storage unit is a self-contained tamper-resistant computer
key-store that acts as a black box for credential storage by accepting
credentials and never returning them.
Cryptographic Accelerator
Cisco 3925E
and Cisco 3945E ISRs ship with a Services Performance Engine that
includes an onboard cryptographic accelerator. It shares security
processing for SSLVPN and IPSec. By default, acceleration of SSL is
disabled so IPSec performance is maximized.
If you want to set up the router as an SSLVPN gateway, enable the SSLVPN feature with the
crypto engine accelerator bandwidth-allocation ssl fair command. To learn more about the cryptographic accelerator, see the Configuring the Security Features module in the Cisco 3900 series, 2900 series, and 1900 series Integrated Services Routers Software Configuration Guide at Cisco.com.

Slot, Port, and Interface Information
Table 1-11 and Table 1-12 show slot, port, and interface numbering ranges.
On the Cisco 2901 router, the numbering format for slots and ports is defined as follows: interface type 0/slot/port.
"0" indicates slots that are built into the chassis of a router. On the
Cisco 2901 router, all slots begin with "0," because all slots are
built into the chassis. On the Cisco 2911, 2921, 2951, and Cisco 3900
series routers, some slots are built into the chassis and some are
external.
Slots
that are part of a network module or an extension voice module have
numbers that begin with "1" or "2," respectively. See the module
documentation for more information.

Periodic Inspection and Cleaning
Periodic
inspection and cleaning of the external surface of the router is
recommended to minimize the negative impact of environmental dust or
debris. The frequency of inspection and cleaning is dependent upon the
severity of the environmental conditions, but a minimum of every six
months is recommended. Cleaning involves vacuuming of router air intake
and exhaust vents and replacement of air filters. See the "Fans, Ventilation, and Airflow" section and the"Replacing a Fan Tray or Air Filter" section.
Caution Sites
with ambient temperatures consistently above 25°C or 77°F and with
potentially high levels of dust or debris may require periodic
preventative maintenance cleaning.
