Standard Bill of Materials (at GA)

The base CISCO2911/K9 ships as a 2U rack-mountable ISR G2 branch router with three integrated 10/100/1000Base-T Gigabit Ethernet (RJ-45) WAN/LAN ports, four Enhanced High-Speed WAN Interface Card (EHWIC) slots (supporting up to two double-wide cards), one Internal Services Module (ISM) slot, two onboard PVDM3 DSP slots for optional voice/video processing, 512 MB DDR2 ECC DRAM (upgradeable to 2 GB), and 256 MB CompactFlash in slot 0 (upgradeable to 4 GB per slot, with an optional second CF slot). The platform includes two USB 2.0 Type-A flash ports, one USB Type-B console port, one RJ-45 serial console port, one auxiliary port, and embedded hardware-accelerated VPN/crypto. It ships with a single AC power supply and Cisco IOS IP Base universal image; Security (SEC), Unified Communications (UC), and AppX licenses are activated via PAK. An optional external Cisco RPS 2300 (with adapter) provides power redundancy.

Rack Mount Kit 19-inch rack mount brackets (included in accessory kit) ACS-2900-RM-19IN 1 Ships standard with chassis; wall-mount option also supported

BOM reflects the standard base CISCO2911/K9 configuration at GA. EHWIC WAN interface cards, PVDM3 DSP modules, ISM modules, and expanded memory/flash are not populated by default and must be ordered separately. The CISCO2911-V/K9 (Voice Bundle) and CISCO2911-SEC/K9 (Security Bundle) are variant SKUs with additional modules/licenses. IOS software part numbers may have been superseded; always cross-reference with Cisco Software Central before ordering. The ISM slot does not equate to a Service Module slot — the 2911 has zero Service Module (SM) slots (only the 2921/2951 and larger have SM slots). Service-parts numbers should be verified against the Cisco spare-parts portal.

BOM is AI-synthesized from public datasheets. Cross-reference with the vendor's spare-parts portal before ordering.
