Cisco C1-C4510R+E to C9410R Migration Guide
A chassis-level migration worksheet for Catalyst 4510R+E estates, separating the C1 ordering code from supervisors, line cards, power and Catalyst 9400 design choices.
C1-C4510R+E identifies a chassis, not a complete switch
Cisco's Catalyst 4500E lifecycle table describes C1-C4510R+E as a Cisco ONE Catalyst 4500E 10-slot chassis rated at 48 Gbps per slot, with a fan and no power supply. The product page must therefore be interpreted as a chassis line. It does not by itself define the installed supervisors, line cards, power supplies, licenses, optics or software image.
The underlying WS-C4510R+E chassis provides ten total slots. Cisco's data sheet assigns two slots to redundant supervisor engines and eight to switching line cards. A replacement project should inventory the populated system rather than multiplying a chassis description by a guessed port count.
The platform has passed its support deadline
Cisco announced October 30, 2020 as the last day to order affected Catalyst C4500E products. The amended bulletin lists October 31, 2025 for both the end of vulnerability and security support and the last date of support. As of this guide's review date, those milestones have passed.
The same bulletin maps the exact C1-C4510R+E chassis PID to C9410R. That row is a manufacturer migration direction, not a complete bill of materials. It does not say that an empty C9410R chassis reproduces the capacity or features of an installed 4510R+E system.
Production 4510R+E
Treat continued operation as a dated risk acceptance while the funded replacement is staged and tested.
Spare chassis
Verify fan, backplane and power compatibility, but do not use spare stock as a substitute for a supported lifecycle plan.
New project
Design on the current Catalyst 9400 architecture instead of creating a new dependency on unsupported C4500E hardware.
Convert the installed chassis into a dependency matrix
| Installed dependency | Evidence to collect | C9410R design question | Acceptance test |
|---|---|---|---|
| Supervisor pair | Exact PID, redundancy mode, software and enabled features. | Which Catalyst 9400 supervisor and license tier meet scale and feature needs? | Supervisor switchover and state synchronization. |
| Line cards | PID, port media, speed, PoE class and used port count. | Which C9400 line cards reproduce copper, fiber, multigigabit and power requirements? | Every production port reaches expected speed and power. |
| Power system | Power-supply PIDs, input circuits, redundancy and measured load. | Required C9410R supplies, power mode, facility feeds and PoE budget. | Feed failure and worst-case powered-device load. |
| Optics and peers | Transceiver PID, fiber type, reach, peer and DOM state. | Current Catalyst 9400 and software compatibility for each optic. | Link stability, errors, redundancy and failover. |
| Control plane | Routes, VLANs, STP, FHRP, multicast, QoS, ACL and telemetry. | Configuration translation and scale limits on the chosen target. | Protocol convergence and policy equivalence. |
C9410R preserves the 10-slot form factor, not the old architecture
Cisco identifies C9410R as the ten-slot replacement chassis. Preserve that useful chassis-capacity starting point, then redesign around Catalyst 9400 supervisors, line cards, power, software and licensing. Avoid assuming that old 4500E components move into the new chassis; the migration should use parts explicitly supported for the Catalyst 9400 platform.
Build the target bill from active ports and measured demand. Reserve slots for redundancy and growth, but do not reproduce empty legacy capacity without a business reason. Validate DNA and network license requirements, IOS XE release support, StackWise Virtual or other resiliency design, telemetry integrations and the operational upgrade procedure.
- C9410R chassis, fan and accessory requirements.
- Supervisor model or redundant pair with required scale.
- Line cards by port media, speed and power class.
- Power supplies, input circuits, redundancy mode and PoE budget.
- Network and subscription licenses with documented term and feature tier.
Prevent chassis-only and bundle-line mistakes
The lifecycle table contains several kinds of C4500E ordering records. C1-C4510R+E is the bare Cisco ONE chassis line, while entries such as C1-C4510RE-DNA and C1-C4510RE-S8+96V+ describe different bundles or upgrade combinations. Their replacement rows can point to a chassis, a configured bundle, a supervisor or a line card. Copying only the nearest C9410R reference can omit the components that made the old system usable.
Normalize each installed or quoted code into one of five classes: enclosure, control engine, access module, energy subsystem or entitlement. Then compare like with like. For example, the chassis row maps to C9410R, but supervisor rows in the same notice map to named C9400 supervisor products, and multigigabit or UPOE upgrade rows map to particular C9400 line-card choices. This prevents a purchasing team from treating several Cisco replacement rows as alternative names for one item.
| Quoted line class | What must appear on the target quote | Common omission |
|---|---|---|
| Ten-slot enclosure | C9410R chassis and required chassis accessories. | Assuming an empty enclosure includes control and access modules. |
| Supervisor | Chosen C9400 supervisor, redundancy quantity and compatible software entitlement. | Reusing a 4500E supervisor or omitting the standby unit. |
| Access ports | C9400 line-card PIDs sized by media, speed, UPOE/PoE class and actual demand. | Counting ports without preserving power or multigigabit capability. |
| Electrical input | Supply PIDs, facility circuit type, cords and redundancy policy. | Quoting “no ps” chassis wording as if power were bundled elsewhere. |
| Software rights | Network and subscription tiers, duration and account assignment. | Assuming an old Cisco ONE record automatically creates a new entitlement. |
Require the supplier to state whether each line is new, spare, remanufactured or subscription-only. A visually complete chassis photograph cannot prove the installed supervisor revision, software rights or PoE capacity. The final acceptance sheet should identify serial numbers and PIDs after delivery, not merely repeat sales descriptions.
Migration and rollback checklist
- Freeze inventory: export hardware, licenses, configuration and live utilization.
- Normalize ports: map every used interface to media, peer, VLAN, PoE and business owner.
- Build the target: choose C9410R components from current Cisco compatibility and ordering data.
- Translate configuration: review commands and defaults instead of pasting the full legacy file.
- Lab failure cases: test supervisor, power, uplink and routing convergence.
- Define acceptance: specify protocol, application, telemetry and powered-device checks.
- Keep rollback viable: preserve the old chassis and cabling state until acceptance is signed.
- Retire securely: erase configuration and document asset disposition after the rollback period.
