Product Overview

ISR4331/K9 Overview

Cisco 4331 Integrated Services Router delivers 100 Mbps to 300 Mbps aggregate throughput and offers one Enhanced service-module (SM-X) slot, which supports for both single- and double-wide service modules provides flexibility in deployment options. The published specification for ISR4331/K9 lists 3 Total onboard WAN or LAN 10/100/1000 ports and 250 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 ISR4331/K9 Changes

Rated Performance Written Into the Quotation

100 Mbps to 300 Mbps published for ISR4331/K9 as its aggregate throughput, confirmed against the current datasheet revision when the line is quoted.

Uplink Capability Settled at Order Not at Install

2 SFP-based ports on ISR4331/K9, so the uplink question is answered on the quotation rather than discovered when the unit is already racked.

Powered Access Without a Separate Injector Build

3 Total onboard WAN or LAN 10/100/1000 ports with 250 W available to powered devices, so access points cameras and phones are fed from the same switch instead of from a parallel power estate.

Serials Issued Before It Ships

The serial list for your ISR4331/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 ISR4331/K9 before the quotation is issued, so the install crew is not blocked by a line nobody costed.

Problems It Solves

Pain Points ISR4331/K9 Removes

  • Performance taken from a family datasheet rather than from this part number, where the published aggregate throughput is 100 Mbps to 300 Mbps
  • Uplink capability fixed at purchase and found insufficient once the access layer behind it was refreshed
  • End of sale announcements that leave a proven design with no supply route for ISR4331/K9
  • End of sale announcements that leave a proven branch design with no supply route
  • Throughput ceilings reached once encryption and inspection are switched on
Who It Is For

Who Benefits Most From ISR4331/K9

Campus Network Teams

Running one access standard across buildings of very different ages

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

Support Contracts

Vendor Support Options Available With ISR4331/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 ISR4331/K9

  1. Confirm the Full Part Number

    Check ISR4331/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.

  2. 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.

  3. Calculate the Power Budget

    Compare the devices this unit will feed against the 250 W available, using realistic device draw with headroom rather than class maximums.

  4. 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.

  5. 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.

  6. 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.

FAQ

ISR4331/K9 Frequently Asked Questions

Is ISR4331/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 ISR4331/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 ISR4331/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 ISR4331/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 ISR4331/K9 Provide

The manufacturer lists maximum endpoint poe power available from poe power supply of 250 W for this model. A PoE budget should be calculated from realistic device draw with headroom rather than from class maximums.

What Performance Is ISR4331/K9 Rated For

The published aggregate throughput is 100 Mbps to 300 Mbps. Full port and performance specifications are issued with the quotation against the current datasheet revision.

Are Uplink Modules and Optics Included With ISR4331/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 ISR4331/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 ISR4331/K9 to My Customer
