Figure 1-34 Label Location on Cisco 4451-X ISR

Additional Help for Locating Cisco 4000 Series ISRs Labels

Use the Cisco Product Identification (CPI) tool to find labels on the router. The tool provides detailed illustrations and descriptions of where 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 required for access to support services.

Built-In Interface Ports

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

Dual Mode GE or SFP Ports

There are dual mode ports available on the router which 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, 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. At a time, it can be used for only one function. As described in the IEEE 802.3ah specification, the SFP port supports auto-media-detection, auto-failover, and remote fault indication (RFI).

Use the media-type command to enable the auto-media-detection and auto-failover features.

You can configure the SFP port by using the media-type configuration command to select either the RJ-45 or the SFP connector. When the media-type is not configured, by default, the auto-select feature is enabled. The auto-select feature automatically detects the media that is connected and links it up. If both media are connected, the media that comes up first is linked, and it is treated as the primary media. This primary media is explicitly indicated as an SFP or RJ-45 link. When the router receives an indication that the primary media is down, the secondary failover media is enabled. After the switchover, when the primary media is later restored, the media does not switch back to the primary media. By default, the RJ-45 port is configured as the primary media-type and if it fails, the media failovers to the SFP port. Conversely, when the SFP port is configured as the primary media-type and if it fails, the media switches to the RJ-45 port.

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 earlier than Windows 7, you must install a Windows USB device driver before using the USB console port.

Note Cisco 4461 supports Mini-USB type B serial port and Micro-USB type B serial port.

Front Panel PoE+ Ports

On Cisco 4451-X ISR and Cisco 4351 ISR, two front panel Ethernet ports are PoE+ (802.3at) compliant ports. These are ports GE 0/0/0 and GE 0/0/1. Cisco 4431 ISR, Cisco 4321 ISR and Cisco 4221 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 1-1 summarizes the LED indicators that are located in the router bezel or chassis, but not on the interface cards and modules.

Network Interface Modules and Service Modules

To install NIMs and SM-Xs on the router chassis, see the “Install and Remove NIMs and SM-Xs on Cisco 4000 Series ISRs” section.

Cisco UCS E-Series Server Modules

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 Cisco 4000 Series Integrated Services Router. For more information on the E-Series Server Modules, see the Cisco UCS E-Series Servers Configuration Guides.

System Flash

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

The CompactFlash is applicable to only Cisco 4451-X ISR. 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.

Cisco 4431 ISRs have a eMMC flash device. The device supports 8GB, 16GB, or 32 GB.

Cisco 4300 Series ISRs have an onboard flash device or an eMMC flash device. It supports 8GB or 16GB.

Note For Cisco 4451-X ISR, you must use Cisco-qualified CompactFlash cards. The 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 does not boot without a flash card in the router.

Note Depending on the model that you have purchased, the routers use a CompactFlash, or an eUSB flash for the internal bootflash memory. Cisco 4431 ISRs have a eMMC flash device. The device supports 8GB, 16GB, or 32 GB. The latest model of Cisco 4451x ISRs support both eUSB and CompactFlash. If a CompactFlash is installed, it will disable the eUSB. However, you can use the old CompactFlash that is available with the routers.

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 “Locate Internal and External Slots for Modules on Cisco 4331 ISR” section on page 6-9 section for more information.

Cisco 4300 ISR platforms support an optional internal SSD mSATA. This device is not hot-swappable and requires opening the chassis to service or upgrade.

Cisco 4461 ISR platform supports an optional internal M2.SSD with the capacity of 800 G. See the “Locate Internal and External Slots for Modules on Cisco 44611 ISR” section on page 6-9 section for more information.

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 “Install PVDM4 on the

Motherboard of Cisco 4400 Series ISRs” section on page 6-33 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 4300 ISRs use a different type of DIMM compared to the 4400 ISRs. For proper operation, the DIMMs for the Cisoc 4400 ISR should not be installed in an Cisco 4300 ISR, 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 only Cisco 4400 Series ISRs. Cisco 4300 Series ISRs 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 4451-X ISR routers)—Available in 8 GB, 16 GB, or 32 GB.
• eUSB flash card (Cisco 4300 ISR router)—Available in 8 GB or 16 GB.

Power Supply

The routers support a variety of power supply configurations. The power supplies module are field-replaceable and externally accessible. Cisco 4331 ISR power supply module is inside the chassis.

Table 1-4 summarizes the power options.

Fans, Ventilation, and Airflow

Chassis Ventilation

Router and chassis temperature is regulated 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 noise. When necessary, the fans operate at higher speeds under conditions of higher ambient temperature. To replace Cisco 4451-X ISR, Cisco 4431 ISR, and Cisco ISR4351 fan trays, see the “Replace a Fan Tray” section.

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.
• 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 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 can 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, because 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.

Gigabit Ethernet Management

Cisco 4000 Series ISRs provides a Gigabit Ethernet Management port, called GE0. This port is the only 1-tuple port on the system. See the Gigabit Ethernet Management Port section in the Software Configuration Guide for the Cisco ISR 4400 Series and Cisco ISR 4300 Series Routers for additional information about the Gigabit Ethernet Management port.
