- 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.
Service module (SM) slots are highly flexible with support for double-wide service modules (SM-D's), which are Service Modules that require two SM slots. SM-Ds in the Cisco 3925 and 3945 provide flexibility for higher-density modules. Service-module slots provide twice the power capabilities relative to the network-module slots.

System Software
The Cisco 3945 is another fine device from the company’s collection of integrated services routers that provide small businesses with big solutions to their communication challenges. The 3945 provides topnotch security while delivering video, application, data, and voice services.
This router has an upgradable and modular SPE (150), three integrated Ethernet ports (10/100/1000). Two ports are capable of SFP or RJ-45 connectivity. The device has four slots for service modules, four onboard slots for digital signal processors (DSPs), four WAN interface slots (enhanced high-speed), and one slot for an internal services module.
The Cisco 3945 fully integrates its power distribution to all modules that support 802.3af PoE (Power over Ethernet). Its power supplies are dual integrated.

The device has excellent security features, including embedded VPN encryption that is hardware-accelerated, integrated threat control which uses the Cisco’s IOS IPS, their IOS zone-based firewall, their IOS firewall, and their IOS Content filtering.
Users’ identities are managed with AAA, as well as by a public key infrastructure.
To unify communications for small businesses, the router has a voice DSP module (high-density-packet) that has been optimized to support both voice and video. It provides standards-certified VoiceXML services for browsers, voicemail support, the capability for 100 sessions of Cisco’s Unified Border Element, and support for Cisco’s Communications Manager Express, as well as the company’s Survivable Remote Site Telephony.
The Cisco 3945 router offers branch offices opportunities for media collaboration, yet is cost effective for small companies who need to watch their bottom line.
