Failure likelihood: 85%
Likely to fail (most → least)
- AC power supply capacitors (PWR-2911-AC)
- Fan assembly (4x internal fans)
- Compact Flash card (256MB default)

Pricing confidence: ●●○○○
Monthly = annual ÷ 12. Real TPM monthly billing is typically ~5–10% higher than this — use annual for accurate budgeting.

Find parts for this unit
Bushido publishes the standard bill of materials above. For substitute part chains, current pricing, and serial- or service-tag-specific configurations, go straight to the manufacturer's own portal — the authoritative source. We don't scrape or resell parts data, and we earn nothing from these links.
Cisco — official sources
Cisco spare-part sourcing runs through Cisco Commerce / partners; the support product page lists compatible modules and optics.
No single manufacturer publishes a cross-vendor "alternative parts" list, and no one official aggregates across all vendors. Lenovo and HPE expose substitute chains publicly; Dell and Sun/Oracle keep them internal or gated. These links are the honest map of where each vendor's data actually lives. If a link is dead or a portal has moved, tell us and we'll fix it.

Standard Bill of Materials (at GA)
The base CISCO2911/K9 ships as a 1U rack-mountable ISR G2 branch router with three integrated 10/100/1000 Mbps RJ-45 Gigabit Ethernet LAN/WAN ports, four Enhanced High-Speed WAN Interface Card (EHWIC) slots occupying the equivalent of four single-wide slots, two onboard PVDM3 DSP slots, one Internal Service Module (ISM) slot, one double-wide Service Module (SM) slot, 512 MB of DDR2 ECC DRAM (soldered on motherboard), a 256 MB external CompactFlash card in slot 0, a single internal AC power supply (PWR-2911-AC, 200 W), two USB 2.0 ports, one RJ-45 serial console port, one USB Type-B console port, and an Cisco IOS Software Universal image with IP Base license pre-activated. Hardware-based cryptographic acceleration, Cisco EnergyWise power management, and support for optional PoE via the AC+PoE power supply variant are included. The platform does not include an SFP port at base config; optional DC power supply (PWR-2911-DC) or PoE power supply (PWR-2911-POE) can replace the default AC unit.

BOM reflects the standard base CISCO2911/K9 configuration at GA (October 2009). EHWIC, NM, SM, PVDM3, and SRE modules are not included in base config and must be ordered separately. The 2911 does not include SFP-based ports at base config (SFP port present only on 2921/2951). Service-parts numbers may have been superseded; always cross-reference with Cisco's spare-parts portal or an authorized reseller before ordering.
BOM is AI-synthesized from public datasheets. Cross-reference with the vendor's spare-parts portal before ordering.
