ISR4321/K9, Cisco ISR 4000 Series Router, 50-100Mbps throughput/2 WAN-LAN ports/1 SFP port

What software options are available for the Cisco 4000 Series?

 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.

What type of Cisco IOS Software is available for the Cisco 4000 Series?

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.

 Are the PoE interfaces PoE+?

 PoE+ is available on the new SM-X Ethernet switch modules as well as on the FPGE ports.

 What power cables work with the Cisco 4000 Series?

 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.

What type of backplane is used between components in the Cisco 4000 Series?

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.

 Is MDI crossover (MDI-X) supported on the four onboard RJ-45 Ethernet interfaces?

Yes.

Do all four ports with both RJ-45 and Small Form-Factor Pluggable (SFP) front panel Gigabit Ethernet (FPGE) connections support failover?

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.

 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?

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.

How many dual inline memory modules (DIMMs) does the Cisco ISR4321/K9 have?

The Cisco ISR4321/K9 has one DIMM.

 What memory upgrade options are available on the Cisco ISR4321/K9?
