What is an internal service module (ISM)?

The ISM is the evolution of the AIM slot available on earlier integrated services routers. It provides additional capabilities such as increased throughput and integration with the MGF in the integrated services routers generation 2. Note that existing AIMs will not work in the new ISM slot.

What is an enhanced high-speed WAN interface card (EHWIC)?

The EHWIC is an updated and enhanced version of the HWIC already available with existing integrated services routers. It offers greater speeds and higher port density than the current HWIC. EHWIC slots can support modules that provide both product-based Cisco Inline Power and PoE. EHWICs are available in two form factors: a singlewide form factor that takes up 1 slot and a doublewide form factor that takes up 2 slots. Note: You can combine two EHWIC slots into one bigger slot (EHWIC-D) by removing the center rail between two individual slots. The EHWIC slot is also backward-compatible with existing HWICs, voice interface cards (VICs), and WICs.

Then how about optional Cisco Enhanced Inline Power (ePoE)? Does it support?

Yes, all 3900 series routers support optional Cisco Enhanced Inline Power (ePoE).

Does CISCO3945E/K9 support multigigabit fabric?

Yes, all 3900 series routers support multigigabit fabric.

Does CISCO3945E/K9 support multicore processor?

Yes, all 3900 series routers support multicore processor.

What capacity increases can I expect for collaboration applications on the CISCO3945E/K9 platforms?

Capacity increases vary across the different collaboration applications. Please refer to the applicable data sheet for specific information.

Can I reuse my existing PVDM2 DSP modules in the CISCO3945E/K9?

Yes. You can install PVDM2s on the motherboard PVDM slots using the PVDM adaptor cards (PVDM2-ADPTR). You can also insert the high-density voice network modules (NM-HDV2s) with PVDM2s into the service-module slots of the Cisco 3900 Series routers by using the network module-to-service module adapter card (SM-NM-ADAPTR).

What is PoE boost?

When a Cisco 2900 is connected to an external RPS device or a Cisco 3900 is configured with a second power supply, these routers can be configured in PoE boost mode. This mode takes advantage of the increased power capacity of the second power source to power additional PoE devices beyond what a single power source could drive.

What power-supply options are available on the CISCO3945E/K9 router?

The table lists the part numbers of the available power supplies for CISCO3945E/K9.

What is the Cisco Services Performance Engine (SPE)?

The Cisco Services Performance Engine is the modular motherboard for the Cisco 3900 Series routers primarily responsible for the processing and forwarding of traffic. Similar to today's Cisco 3845 motherboard, the SPE houses the PVDM slots, ISM slot, and the EHWIC slots in addition to the system memory. The SPE provides a modular approach to system upgradability such that you can upgrade Cisco 3900 Series routers deployed in the field with new performance and capabilities with a simple SPE swap. This form of investment protection helps ensure that routers deployed today will be upgradable for years to come with the latest innovations without the need for complete platform replacement.

What kind of performance can I expect from the CISCO3945E/K9?

The CISCO3945E/K9, equipped with SPE250, offers high performance suitable for branch offices and businesses.

Can the CISCO3945E/K9 support large-scale VPN networks?

Yes, with its robust security features and 4 Gigabit Ethernet ports, it's ideal for managing large VPN networks.

Is the CISCO3945E/K9 router easy to install?

It requires some technical knowledge but comes with a comprehensive guide for step-by-step installation.

What are the primary application scenarios for the CISCO3945E/K9?

Designed for medium to large branch offices, providing high-capacity voice, video, and data communication.

How does the CISCO3945E/K9 compare with other routers in the same category?

It excels in scalability, security features, and integrated services, standing out from competitors.

What kind of maintenance does the CISCO3945E/K9 require?

Regular updates and security patches are recommended for optimal performance and security.

Are there any recommended accessories that enhance the CISCO3945E/K9's capabilities?
