Cisco Router ISR4331/K9 100 Mbps to 300 Mbps 2*RJ-45-based Ports 2*SFP-based Ports ISR4331/K9 Overview Cisco 4331 Integrated Services Router delivers 100 Mbps to 300 Mbps aggregate throughput and offers one Enhanced service-module (SM-X) slot, which supports for both single- and double-wide service modules provides flexibility in deployment options. The Cisco 4000 Family Integrated Services Router (ISR) revolutionizes WAN communications in the enterprise branch. With new levels of built-in intelligent network capabilities and convergence, it specifically addresses the growing need for application-aware networking in distributed enterprise sites. These locations tend to have lean IT resources. But they often also have a growing need for direct communication with both private data centers and public clouds across diverse links, including Multiprotocol Label Switching (MPLS) VPNs and the Internet. The Cisco 4000 Family contains the following platforms: the 4461, 4451, 4431, 4351, 4331, 4321 and 4221 ISRs.

A:The 4000 Series has separate data and control-plane memory. The control-plane memory comes with 4 GB as the default, and is upgradable up to 16 GB based on various platforms. The data-plane memory comes with 2 GB as the default and is not currently upgradable. Q:How many dual inline memory modules (DIMMs) does the Cisco ISR4331-SEC/K9 have? A:The Cisco ISR4331-SEC/K9 has two DIMMs Q:In the case of control-plane memory, can I put a 4-GB DIMM in one slot and a 2-GB DIMM in the other slot? A:No. the 4000 Series expects both DIMM slots to have the same size of memory, as an example, it must have either 4-GB memory in both slots for a total of 8 GB of control-plane memory, or 2-GB memory in both slots, for a total of 4 GB of control-plane memory. This setup is necessary because these platforms interleave memory devices for faster access. Q:Do all four ports with both RJ-45 and Small Form-Factor Pluggable (SFP) front panel Gigabit Ethernet (FPGE) connections support failover? A:Yes. You can configure auto-failover on any of the front-panel ports with both RJ-45 and SFP connections. When auto-failover is configured, if the primary interface type fails, either RJ-45 or SFP, the other media type becomes active and allows traffic to continue over the backup physical connection. In this scenario, the backup connection needs to be connected with the same speed and duplex as the primary connection.Note that the auto-failover feature as described does support one Gigabit Ethernet interface acting as a backup to another. The two physical connections available on a single Gigabit Ethernet interface simply provide failover if a link fails. Q:Is MDI crossover (MDI-X) supported on the four onboard RJ-45 Ethernet interfaces? A:Yes. Q:What type of backplane is used between components in the Cisco 4000 Series? A:The 4000 Series uses multigigabit fabric (MGF) for Layer 2 connectivity between the modules. On the 4451-X, the MGF can provide either 2 Gbps to all NIM slots or up to 10 Gbps to all SM-X slots. The MGF is completely nonblocking and can forward in excess of 50 Gbps. Q:What power cables work with the Cisco 4000 Series? A:All power-supply options for the 4000 Series use a standard IEC C13 connector. No special IEC C15 cord is necessary for the Power over Ethernet (PoE) power supply because higher-efficiency power supplies (85 percent) are used in the 4000 Series. This cord thus helps lower the maximum current the power supplies can draw. Q:Are the PoE interfaces PoE+? A:PoE+ is available on the new SM-X Ethernet switch modules as well as on the FPGE ports. Q:What type of Cisco IOS Software is available for the Cisco 4000 Series? A:The Cisco 4000 Series runs the same feature-rich Cisco IOS XE Software as the current-generation Cisco ASR 1000 Series. By using the same software release as the Cisco ASR 1000 Series, the Cisco 4000 Series benefits from a rich history of branch-office feature development as well as ongoing feature development. Q:What software options are available for the Cisco 4000 Series? A:One change that customers like is the Cisco IOS Software images available on the ISR G2 routers, which reduce numerous software images into one. Therefore, the Cisco 4000 Series has a single Cisco IOS XE Software image. This image is known as a universal image. It contains all features and functions in a single software image. You can selectively enable functions within this universal image by using Cisco Software Activation Licenses that activate capabilities within that image. You now need only a single Cisco IOS XE Software image for the router regardless of the features or functions you need for any particular area in your network. Business
