The Cisco 3900 Series offers field-replaceable SPEs which allow you to protect your initial investment in the Cisco 3900 platform for a longer time period and scale router performance as your network and branch-office needs grow.
Figure 6 shows the internal view of the CISCO3945/K9.
The Cisco 3945 router supports two memory slots which has been installed two 512MB memory cards. When upgrading the memory, the same capacity of memory cards must be inserted into the two memory slots in the same time. It doesn't support to use only a single memory slot.

I need to buy a router series 3900 model 3945 / k9 doubt is further if I have to buy software CME, E1 card is also recommened.
If you need CME, you should buy License FL-CME-SRST. As for E1 Card, HWIC-1CE1T1-PRI is the most basic module.
I want to limit bandwidth on one of my 3945 router interface can you share which is best option to do this?
You can do this in one of two ways. - Traffic Shaping: is predominantly for egress traffic -(Usually comes into play on your routers when your physical wan lines exceeds the your traffic rate set by the ISP or your neighboring site) - Traffic Policing: is used for ingress traffic (usually originating from you LAN,-entering first device in network from being overrun with too much traffic)
On the Cisco ISR G2 routers with the SEC-K9 license, what tunnel count and performance throughput are available?
The SEC-K9 permanent licenses apply to the Cisco 1900, 2900, and 3900 ISR G2 platforms; these licenses limit all encrypted tunnel counts to 225 tunnels maximum for IP Security (IPsec), Secure Sockets Layer VPN (SSL VPN), a secure time-division multiplexing (TDM) gateway, and secure Cisco Unified Border Element (CUBE) and 1000 tunnels for Transport Layer Security (TLS) sessions. The SEC-K9 license limits encrypted throughput to less than or equal to 85-Mbps unidirectional traffic in or out of the ISR G2 router, with a bidirectional total of 170 Mbps. This requirement applies for the Cisco 1900, 2900, and 3900 ISR G2 platforms.
What is the exact HSEC-k9 license?
The HSEC-K9 license removes the curtailment enforced by the U.S. government export restrictions on the encrypted tunnel count and encrypted throughput. HSEC-K9 is available only on the Cisco 2921, Cisco 2951, Cisco 3925, Cisco 3945, Cisco 3925E, and Cisco 3945E. With the HSEC-K9 license, the ISRG2 router can go over the curtailment limit of 225 tunnels maximum for IP Security (IPsec) and encrypted throughput of 85-Mbps unidirectional traffic in or out of the ISR G2 router, with a bidirectional total of 170 Mbps. The Cisco 1941, 2901, and 2911 already have maximum encryption capacities within export limits.
What countries are classified license-free zones?
Countries belonging to the EU license-free zone include Australia, Austria, Belgium, Bulgaria, Canada, Cypress, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Japan, Latvia, Lithuania, Luxembourg, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, United Kingdom, and the United States.
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 power-supply options are available on the CISCO3945/K9 router?
The table lists the part numbers of the available power supplies for CISCO3945/K9.
AC + PoE option
Redundant power supply
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.
Can I reuse my existing PVDM2 DSP modules in the CISCO3945/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 capacity increases can I expect for collaboration applications on the CISCO3945/K9 platforms?
Capacity increases vary across the different collaboration applications. Please refer to the applicable data sheet for specific information.
