Product Overview
ISR4351/K9 Overview
Cisco 4351 Integrated Services Router, which supports 3 Network Interface Modules (NIM) slots, delivers 200 Mbps to 400 Mbps aggregate throughput. The published specification for ISR4351/K9 lists 3 Total onboard WAN or LAN 10/100/1000 ports and 500 W available to powered devices. It is supplied new factory sealed, with the serial list issued before shipment and 12 months replacement warranty as standard.
Key Benefits
What Owning ISR4351/K9 Changes
Powered Access Without a Separate Injector Build
3 Total onboard WAN or LAN 10/100/1000 ports with 500 W available to powered devices, so access points cameras and phones are fed from the same switch instead of from a parallel power estate.
Rated Performance Written Into the Quotation
200 Mbps to 400 Mbps published for ISR4351/K9 as its aggregate throughput, confirmed against the current datasheet revision when the line is quoted.
Uplink Capability Settled at Order Not at Install
3 SFP-based ports on ISR4351/K9, so the uplink question is answered on the quotation rather than discovered when the unit is already racked.
Serials Issued Before It Ships
The serial list for your ISR4351/K9 consignment is released before despatch, so it can be checked on the manufacturer portal while the goods are still with us.
A Complete Bill of Materials
Modules optics rails and power options are reviewed against ISR4351/K9 before the quotation is issued, so the install crew is not blocked by a line nobody costed.
Problems It Solves
Pain Points ISR4351/K9 Removes
- End of sale announcements that leave a proven branch design with no supply route
- Throughput ceilings reached once encryption and inspection are switched on
- Modules and interface cards quoted separately which breaks the budget late
- Hardware arriving without the licence tier the design assumed
- PoE budgets sized for desk phones and now asked to carry Wi-Fi 6 access points, where 500 W is the figure that decides it
Who It Is For
Who Benefits Most From ISR4351/K9
Hosting Providers
Building repeatable nodes where every batch has to match the last one
Maintenance and Support Companies
Holding spares against generations the mainstream channel has already dropped
System Integrators
Bidding work that needs firm pricing and a written lead time before the end client is quoted
Managed Service Providers
Standardising hardware across many customer sites and needing the same SKU available again

Support Contracts
Vendor Support Options Available With ISR4351/K9
Contracts are registered under the end user name rather than under a reseller name, so the entitlement sits with the organisation that owns the outage. See the support contract guide for how the response levels differ.

Use Guide
Deployment Guide for ISR4351/K9
Confirm the Full Part Number
Check ISR4351/K9 character for character including any suffix. On this class of hardware a single trailing character commonly changes the software tier, the power option, or whether a bundle is included.
Check Site Prerequisites
Confirm rack space, power feed, cabling and any uplink or accessory dependency before the order rather than on the day of installation.
Calculate the Power Budget
Compare the devices this unit will feed against the 500 W available, using realistic device draw with headroom rather than class maximums.
Settle the Uplink and Optics
Match the uplink module and transceiver to the platform, the measured span and the fibre already installed, and order them on the same line.
Record It on Arrival
Photograph the sealed carton, reconcile the serial against the list supplied before shipment, then open and confirm the unit matches the label.
Bench Power Before Racking
Power the unit, capture the software version and the port or drive inventory, and record it while the unit is still accessible.

Where It Goes
Industries That Deploy It
Service Provider
Repeatable CPE and aggregation hardware supplied at the volume and consistency a managed service contract depends on.
Manufacturing and Logistics
Connectivity for plant floors, warehouses and distribution sites built for continuous operation rather than office hours.
Solutions
Programmes It Is Supplied Under
Support Contracts and SmartNet
A support contract registered under a reseller name is of limited use to the organisation that owns the outage. Entitlement is written under the end user name.
Global Logistics and Drop Shipping
Hong Kong is a practical despatch point for most of the world. Consignments go to the site, not to a central store and then out again.
Procurement for System Integrators
An integrator carries the risk between quoting a client and receiving the hardware. Firm pricing and a written lead time per line is what makes that risk manageable.

Project Cases and Guides
Regional Bank Branch Refresh Across 140 Sites
The branch edge had reached end of software support and the estate had drifted into four different router models bought across eight years
Manufacturer Multi Site Network Standard
Each site had bought its own network hardware locally, so no two plants ran the same equipment and no spares could be shared
New Versus Refurbished Network Hardware
The choice is rarely about quality. It is about entitlement, traceability and what happens eighteen months after the invoice is paid.
Support Contracts Explained for Buyers
A support contract is bought once and used on the worst day of the year. The level and the name it is registered under both matter.
Network Refresh Planning Checklist
Refresh programmes fail on supply far more often than on design. This is the sequence that keeps a phased rollout on its dates.
FAQ
ISR4351/K9 Frequently Asked Questions
Is ISR4351/K9 New or Refurbished
Standard supply is new factory sealed in the original vendor carton. If a quotation offers another condition that is stated explicitly in writing before you commit.
Can I Get the Serial Numbers for ISR4351/K9 Before Payment Clears
Yes. Serials are issued before shipment so you can check them on the manufacturer portal while the goods are still with us.
What Is the Lead Time for ISR4351/K9
Availability is confirmed in writing per line at quotation rather than as a project average, because one late line is what moves an installation date.
What Warranty Does ISR4351/K9 Carry
12 months replacement as standard. A vendor support contract is available separately and is registered under the end user name.
How Much PoE Power Does ISR4351/K9 Provide
The manufacturer lists maximum endpoint poe power available from poe power supply of 500 W for this model. A PoE budget should be calculated from realistic device draw with headroom rather than from class maximums.
What Performance Is ISR4351/K9 Rated For
The published aggregate throughput is 200 Mbps to 400 Mbps. Full port and performance specifications are issued with the quotation against the current datasheet revision.
Are Uplink Modules and Optics Included With ISR4351/K9
They are quoted as separate lines and reviewed against the chassis before the quotation is issued, so they reach site in the same consignment as the unit they belong to.
Can You Ship ISR4351/K9 to My Country
Yes. Consignments go worldwide by courier or freight from Hong Kong, with the routing chosen against the destination clearance regime and your deadline.
Can You Drop Ship ISR4351/K9 to My Customer
Yes. Consignments can be released directly to an end customer address under your own documentation.
