Cisco 3945 ISR — High-Performance Modular Integrated Services Router
The Cisco 3945 Integrated Services Router (ISR G2) is a 2U modular enterprise router featuring 3 × 10/100/1000 GbE WAN ports, 4 × eHWIC slots, 4 × Service Module slots, hardware IPsec VPN, and a high-performance multicore CPU. This unit ships with a C3900-SPE150/K9 Services Performance Engine, 2 × VIC2-2BRI voice interface cards, a VWIC3-1MFT-T1/E1 voice/WAN card, and an SM-D-ES3G-48-P 48-port GbE switch module installed. Backed by a full 12-month Reboot IT warranty. Note: No flash card or Cisco IOS image is included.
Key Benefits
- 4 Service Module slots: Double the capacity of the 2951 — install high-density WAN, voice, security, and switching modules simultaneously for complex multi-service branch deployments
- SPE-150 performance engine: The included C3900-SPE150/K9 offloads crypto and processing, enabling higher VPN and routing throughput than base-model ISR G2 platforms
- Hardware IPsec VPN: Dedicated AES/3DES encryption accelerator handles site-to-site and remote-access VPN tunnels without impacting route processor performance
- Included voice modules: Ships with 2 × VIC2-2BRI-NT/TE and 1 × VWIC3-1MFT-T1/E1 — ready for ISDN BRI and T1/E1 voice gateway deployment out of the box
- 48-port GbE switch module: The SM-D-ES3G-48-P provides 48 Gigabit Ethernet switching ports in a single service module slot, eliminating a separate access switch at smaller sites
- 1 GB DRAM: Higher memory capacity supports larger routing tables, more concurrent VPN tunnels, and memory-intensive IOS feature sets
Performance in Use
The Cisco 3945 aggregates multiple WAN connections (MPLS, Metro Ethernet, broadband), terminates IPsec VPN tunnels, and enforces security policies — all in a single chassis. The SPE-150 engine significantly increases throughput headroom over entry-level ISR G2 configurations, making the 3945 a strong choice for medium-to-large branch offices and multi-service hub sites.
The included SM-D-ES3G-48-P 48-port GbE switch module turns the 3945 into a combined router-plus-switch platform. This reduces rack space and cable complexity at branch sites where a dedicated access switch would otherwise be required, while the multigigabit fabric (MGF) ensures efficient communication between service modules and the route processor.
For unified communications deployments, the installed VIC2-2BRI and VWIC3-1MFT-T1/E1 cards enable PSTN gateway configuration for SIP or H.323 trunks alongside data routing on the same chassis. Network engineers studying for CCIE Enterprise or Voice can use the 3945 as a realistic multi-service lab platform covering routing, VPN, voice gateway, and switching scenarios simultaneously.

Frequently Asked Questions
Does this come with a flash card or Cisco IOS?
No — this unit ships without a flash memory card and without Cisco IOS software. You will need to purchase a compatible CompactFlash card and obtain a Cisco IOS licence separately before the router can operate.
What modules are included with this unit?
This unit includes: C3900-SPE150/K9 (Services Performance Engine 150), 2 × VIC2-2BRI-NT/TE (ISDN BRI voice interface cards), 1 × VWIC3-1MFT-T1/E1 (T1/E1 voice/WAN card), and 1 × SM-D-ES3G-48-P (48-port Gigabit EtherSwitch module). Module configuration may vary by unit.
How does the 3945 differ from the 2951?
The 3945 has 4 Service Module slots (vs 2 on the 2951), 1 GB DRAM (vs 512 MB), and higher overall throughput capacity. It is suited to medium-to-large branches with higher concurrent service demands across routing, security, voice, and switching.
Is this suitable for CCNP or CCIE lab use?
Yes — the 3945 is an excellent lab platform for CCNP Enterprise and CCIE Enterprise or Voice study. The included voice and switch modules extend lab scenarios to cover unified communications, multi-tier LAN design, and T1/E1 WAN simulation.
What warranty is included?
A 12-month Reboot IT warranty covers all hardware components from the date of purchase.
How does shipping work?
Shipping costs apply based on size and destination — rates are calculated at checkout.
