ISR4431/K9, Cisco ISR 4000 Series Router, 1Gbps throughput/4 WAN-LAN ports/Multi-Core CPU

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.

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. Like the Cisco 3900 Series, 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 ISR4431/K9 have?

 The Cisco ISR4431/K9 has three DIMM slots.

What memory upgrade options are available on the Cisco 4000 Series?

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.

Can I use the enhanced high-speed WAN interface cards (EHWICs) available on the Cisco 1900, 2900, and 3900 Series ISRs on the Cisco 4000 Series ISRs?

EHWIC modules available on the Cisco ISR Generation 2 (ISR G2) routers will not work with the 4000 Series ISRs. The 4000 Series is targeted at new branch-office environments requiring high bandwidth and greater application performance, making most EHWICs unapplicable. Also, the newer NIM architecture allows for faster, more capable modules on a high-end platform.

Can the NIMs or service modules available on the Cisco 4000 Series work on the Cisco ASR 1000 Series?

The service modules will work with the Cisco ASR 1000 Series. Select NIMs will also work with the ASR 1000 Series.

Are the Cisco ASR 1000 Series Shared Port Adapter (SPA) cards supported on the 4000 Series ISRs?

No. SPAs are not compatible with the 4000 Series ISRs.

 What software are the Cisco 4000 Series ISRs capable of running?

The 4000 Series ISRs run Cisco IOS XE Software. The initial version will be Cisco IOS XE Software Release 3.9.1. The 4300 and 4431 ISRs were released with Cisco IOS XE Software Release 3.13, and the 4200 Series ISRs were released with Cisco IOS XE Software Release 16.4.1.
