The Cisco CISCO2921/K9 is a 3-port Gigabit Integrated Services Router from the Cisco 2900 Series (launched 2010–2011) — a 1RU rack-mountable, modular branch-office router designed for medium-sized businesses, branch offices, and distributed enterprise sites requiring advanced routing, security, voice, wireless LAN controller functionality, and WAN optimization in a compact form factor.

Product Description

The Cisco 2921 is a high-performance, modular ISR (Integrated Services Router) that combines routing, security, voice, and application services into a single platform. It features:

  • 3 onboard Gigabit Ethernet RJ-45 ports (GigabitEthernet0/0, 0/1, 0/2) — configurable as LAN or WAN interfaces
  • 3 Enhanced High-Speed WAN Interface Card (EHWIC) slots for expansion (e.g., T1/E1, serial, ISDN, LTE, additional Ethernet, voice modules)
  • 1 double-wide EHWIC slot (can be used for larger modules like SM-1T3/E3)
  • 1 Internal Service Module (ISM) slot for optional security/acceleration cards (e.g., IPSec VPN, WAAS)
  • 1 Packet Voice Data Module (PVDM3) slot for voice DSPs (supports up to 100 voice channels with PVDM3-100)
  • Dual redundant power supply bays (default single PSU; optional second for redundancy)
  • Redundant hot-swap fans (front-to-back airflow)

It runs Cisco IOS (or IOS-XE in later images) with full modular software licensing:

  • IP Base (default) — basic routing, security, QoS
  • Upgradable to Security, UC (Unified Communications), AppX (Application Experience), or full UC license bundles

Common deployment scenarios:

  • Branch-office WAN router with MPLS/Internet breakout
  • DMVPN hub/spoke or GETVPN
  • Voice gateway (SRST, CME, CUBE)
  • SD-WAN edge (with Viptela/IWAN)
  • Small wireless LAN controller (up to 50 APs with UC license)

• 3 onboard Gigabit Ethernet ports (RJ-45)
• 3 EHWIC slots, 1 service module slot, 2 PVDM slots
• Up to 480 Mbps aggregate throughput (with services)
• Embedded security (firewall, IPSec VPN, zone-based firewall)
• Modular design for voice, wireless, application optimization
• Cisco IOS software with SD-WAN readiness
• Dual redundant power supply support
• Hardware encryption and high-availability features
