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 and Cisco Integrated Service Routers Generation 2 document on Cisco.com.

The UDI has two main components:

  • Product ID (PID)
  • Serial number (SN)

Labels on the Router

Though your router might be different from the one shown in Figure 1-21, the label location is similar for all routers in the Cisco ISR 4400 and Cisco ISR 4300 series. Figure 1-21 shows the location of the labels on the Cisco ISR4451-Xs.

For Additional Help Locating Labels on the Router

Use the Cisco Product Identification (CPI) tool to find labels on the router. The tool 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 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.

Hardware Features

This section describes the hardware features in the routers.

Built-In Interface Ports

 

The Cisco 4000 Series ISR have multiple 10/100/1000 front panel ports, SFPs, and 10/100/1000 management ports.

Dual Mode GE/SFP Ports

There are dual mode ports available on the router that can function as GE or SFP ports.

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, but are not restricted to 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 with the same number. It can only be used for one or the other function at one time. 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:

  • Always use the RJ-45 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 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 can be used as an alternative to the RJ-45 console port. For Windows operating systems older than Windows 7, you must install a Windows USB device driver before using the USB console port.

Front Panel PoE+ Ports

On the Cisco ISR4451-X, Cisco ISR4431, and Cisco ISR4351 two of the front panel Ethernet ports are PoE+ (802.3at) compliant ports. These are ports GE 0/0/0 and GE 0/0/1. The Cisco ISR4431 and Cisco ISR4421 do not support front panel PoE+.

System PoE power supplies do not provide power to the front panel ports.

Internal PoE Daughter Card

The internal PoE daughter card provides a total of 30.8 watts of power across the two ports.

LED Indicators

Table 1-2 summarizes the LED indicators that are located in the router bezel or chassis, but not on the interface cards and modules.


Note For module LEDs, please refer to the respective module installation guides for each module.

Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030



Warning This equipment must be installed and maintained by service personnel as defined by AS/NZS 3260. Incorrectly connecting this equipment to a general-purpose outlet could be hazardous. The telecommunications lines must be disconnected 1) before unplugging the main power connector or 2) while the housing is open, or both. Statement 1043


See the Overview of Cisco Network Modules and Service Modules for Cisco Access Routers document for general information and single- and double-wide slot numbering.

See the “Installing and Removing NIMs and SM-Xs” section for instructions that describe how to install SM-Xs and NIMs in the router.

See the Overview of Cisco Interface Cards for Cisco Access Routers for general interface card information.

See the Installing Cisco Interface Cards in Cisco Access Routers document, for instructions that describe how to install legacy interface cards in the router.


Note See the router product page on Cisco.com for a list of supported network modules and interface cards.


Network Interface Modules and Service Modules

To install NIMs and SM-X s on the router chassis, see the “Installing and Removing NIMs and SM-Xs” section.

Cisco UCS E-Series Server Modules

The Cisco UCS E-Series Servers (E-Series Servers) are the next generation of Cisco UCS Express servers. E-Series Servers are a family of size, weight, and power efficient blade servers that are housed within the Generation 2 Cisco Integrated Services Routers (ISR G2) and the Cisco 4400 and Cisco 4300 Series Integrated Services Router. These servers provide a general-purpose compute platform for branch-office applications deployed either as bare-metal on operating systems, such as Microsoft Windows or Linux; or as virtual machines on hypervisors, such as VMware vSphere Hypervisor™, Microsoft Hyper-V, or Citrix XenServer.

System Flash

The routers use a CompactFlash or an eUSB flash for the internal bootflash memory depending on the model that you have purchased. The CompactFlash and eUSB flash stores the operating system software image.

The CompactFlash is applicable only to the Cisco ISR4451-X. Each model supports 1 internal CompactFlash 8-GB, 16-GB, or 32-GB memory card. The CompactFlash is located behind the fan tray on the router chassis.

The ISR4431 routers have a eMMC flash device. It supports 8GB, 16GB, or 32 GB.

The ISR 4300 series routers have an onboard flash device or a eMMC flash device. It supports 8GB or 16GB.


Note For the Cisco ISR 4451-X, you must use Cisco-qualified CompactFlash cards. Use of any other cards during normal network operation can affect system performance or reliability.



Note Do not run the router without a CompactFlash card installed. Cisco IOS XE software will not boot without a flash card in the router.


Solid State Drives

The NIM slots in the router support a field-replaceable solid state drive module with a dual-SSD SATA slot. The NIM can be installed in any bay slot 0. The SSDs are hot-swappable as part of normal operation. See the “Overview of the SSD Carrier Card NIM (NIM-SSD)” section section for more information.

The Cisco ISR4300 platforms support optional internal SSD mSATA. This device is not hot-swappable and requires opening the chassis to service or upgrade.

Packet Voice Digital Signal Processor Modules

The Packet Voice Digital Signal Processor Modules (PVDM4s) add additional voice capabilities to the routers. The PVDM4 is installed inside the chassis of the router. See the “Installing the PVDM4 on the Motherboard of the Router” section for installation instructions.

Memory

The routers contain the following types of memory:

  • DIMMs—Stores the running configuration and routing tables and is used for packet buffering by the network interfaces. Cisco IOS XE software executes from memory. Supported module types are Dual In-Line Memory Modules (DIMMs).

Note The DIMMs are interchangeable although the same sizes are not supported in all locations. The Cisco ISR4300 routers use a different type of DIMM compared to the ISR4400 routers. For proper operation, the DIMMs for the ISR4400 should not be installed in an ISR4300 and vice a versa. The single forwarding plane DIMM must have a 2-GB DIMM that is exactly like one of the two DIMMs used for the control plane with 4 GB of default memory. The control plane uses two DIMMs and they must be exactly the same type and density. This applies to the Cisco ISR4400 series only. The Cisco ISR4300 series do not have a distinct forwarding plane DIMM.


  • Boot/NVRAM—Stores the bootstrap program (ROM monitor), and the configuration register. The boot/NVRAM is not serviceable.
  • Flash memory—Internal bootflash memory. For details, see the“System Flash” section.

 

  • CompactFlash memory card (Cisco ISR4451-X routers)—Available in 8 GB, 16 GB, or 32 GB.
  • eUSB flash card (Cisco ISR 4300 router)—Available in 8 GB or 16 GB.

Power Supply

The routers support a variety of power supply configurations. The power supplies are field-replaceable and externally accessible. The Cisco ISR4331 power supply is not externally accessible, it is inside the chassis.

The Cisco ISR4451-X and Cisco ISR4431 routers support dual, hot-swappable power supplies. The PoE Power Supply Converter on the ISR4451-X is also dual and hot-swappable.

Table 1-4 summarizes the power options.

Fans, Ventilation, and Airflow

Chassis Ventilation

Cooling is supported with internal fans. An onboard temperature sensor controls the fan speed. The fans are always on when the router is powered on. Under most conditions, the fans operate at the slowest speed to conserve power and reduce fan noise. The fans operate at the higher speeds when necessary under conditions of higher ambient temperature. To replace the Cisco ISR4451-X, Cisco ISR4431, and Cisco ISR4351 fan trays, see the “Replacing a Fan Tray” section.

Figure 1-22 shows the Cisco ISR4451-X airflow and Figure 1-23 shows the Cisco ISR4431 airflow. The direction of airflow is same on all the Cisco 4000 Series ISR platforms.

About Slots and Interfaces

This section covers the following topics:

About Slot, Subslot (Bay), and Port Numbering

The routers supports two types of interface modules: Enhanced Service Modules (SM-X) and Network Modules (NIMs).

In most cases, the router designates its interfaces using a 3-tuple notation that lists the slot, bay, and port. The 3-tuple value is zero based. An example of a 3-tuple is 0/1/2. This refers to slot 0, the second bay in slot 0 (the first bay is 0 so the second bay is 1), and the third port in bay 1. See Table 1-5 for more examples.

  • Slots and bays are numbered from the left to the right, and from the top to the bottom.
  • NIMs are designated by the number of the first slot that they occupy. A double-wide NIM occupies two slots, but its designation is only the left-most slot number.
  • The auxiliary (AUX) serial port and console (CON) serial port do not have slot, bay, or port numbers.
  • The GE management port is named GE 0 and has a port number. It does not have a slot or bay number.
  • The two USB ports are named USB0 and USB1. They do not have slot or bay numbers. The Cisco ISR4331 and Cisco ISR4321 only have one USB port.

Note USB0 and USB1 can be used to insert flash drives.

Slot Numbering

Slots are numbered 0, 1 and 2.

About Slot 0

The following are the main features of Slot 0:

  • Slot 0 is the motherboard and not removable. It is reserved for integrated ports and NIMs.
  • The front panel GE ports (or native interface ports) always reside in slot 0 and bay 0. The ports are called Gigabitethernet 0/0/0, Gigabitethernet 0/0/1, Gigabitethernet 0/0/2, and Gigabitethernet 0/0/3 (up to as many ports supported on the particular router).
  • PVDM4s do not have an external slot number. Therefore, the nomenclature for PVDM4s always has 0 in the first tuple. For example, the 3-tuple for an PVDM4 might be 0/4/x.

Subslot/Bay Numbering

  • Integrated devices, also known as integrated ports or FPGEs, and integrated NIMs reside in a fixed section of bay 0.
  • Main board NIMs bays start at bay 1, since the integrated devices and integrated NIMs take up bay 0.
  • The bay numbers for PVDM4s start with the next bay number after the last NIM bay number.

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. See the “Fans, Ventilation, and Airflow” section.


Caution Sites with ambient temperatures consistently above 25°C or 77°F and with potentially high levels of dust or debris might require periodic preventative maintenance cleaning.
