N9K-SUP-A+ Description
N9K-SUP-A+ is a Cisco Nexus 9500 Supervisor A+ module for Nexus 9500 modular chassis control-plane and management-plane operation.
This supervisor module uses a 4-core, 8-thread 1.8GHz x86 processor with 16GB DRAM. Cisco lists it for Cisco Nexus 9500 deployments, and redundant supervisors should be the same type within the chassis for supported supervisor redundancy.
Before requesting a quote, confirm the installed chassis, current supervisor type, NX-OS release, ACI or NX-OS mode, and any line-card limitations that affect N9K-SUP-A+.

Application Scenarios
Use N9K-SUP-A+ when an installed Nexus 9500 chassis needs a replacement Supervisor A+ module. The buyer should match the existing supervisor generation and confirm the installed software release before ordering.
Choose this module when the chassis requires active-standby supervisor redundancy using Supervisor A+ modules. Cisco guidance requires redundant supervisors to be the same type within the chassis for supported redundancy.
N9K-SUP-A+ can be evaluated as a spare for Nexus 9500 environments that already run Supervisor A+ modules. Engineers should confirm that the chassis does not use unsupported -R or -R2 line-card combinations before purchase.

- Choose N9K-SUP-A+ when the Nexus 9500 chassis already uses Supervisor A+ and needs a like-for-like spare or replacement.
- Compare N9K-SUP-B or N9K-SUP-B+ when the project requires the Supervisor B family, higher DRAM, or a Cisco-supported supervisor transition from Supervisor A.
- Do not mix Supervisor A/A+ and Supervisor B/B+ modules in a dual-supervisor chassis except during a Cisco-supported migration process.
- Confirm the installed supervisor type, hardware revision, and support entitlement before ordering replacement supervisor inventory.
Selection Guide
1. Choose N9K-SUP-A+ for Supervisor A+ continuity
Select N9K-SUP-A+ when the installed Nexus 9500 system already uses Supervisor A+ modules and the goal is replacement, sparing, or matching a redundant supervisor pair.
2. Verify the second supervisor before ordering
For dual-supervisor operation, confirm the installed supervisor model. Redundant supervisors should be the same type within the chassis to support active-standby redundancy.
3. Check NX-OS release and line-card limitations
Confirm that the installed NX-OS release supports Supervisor A+. Cisco release notes also state that N9K-SUP-A and N9K-SUP-A+ are not supported on Cisco Nexus 9504 and 9508 switches with -R and -R2 line cards.
4. Choose Supervisor B family for supported migration requirements
If the project is migrating from Supervisor A family to Supervisor B family, use Cisco migration guidance and quote the correct matching Supervisor B pair rather than mixing long-term supervisor types.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Chassis Model |
Nexus 9504, Nexus 9508, or Nexus 9516 |
Confirms the supervisor is for the Cisco Nexus 9500 platform |
|
Existing Supervisor Type |
Supervisor A, A+, B, or B+ |
Redundant supervisor pairs should use the same supervisor type |
|
Supervisor Quantity |
One or two supervisors in the chassis |
Cisco lists a maximum of two Nexus 9500 supervisor modules per chassis |
|
Operating Mode |
Cisco ACI or Cisco NX-OS |
Deployment mode affects software and compatibility checks |
|
NX-OS Release |
Minimum release and current target release |
Supervisor A+ requires supported software before deployment |
|
Line Card Mix |
Whether the chassis uses -R or -R2 line cards |
Cisco notes N9K-SUP-A and N9K-SUP-A+ limitations with some -R and -R2 line-card deployments |
|
Airflow Direction |
Port-side intake |
Airflow direction must match the Nexus 9500 chassis cooling design |
|
Spare Part Requirement |
Base part or spare part ordering format |
Cisco lists N9K-SUP-A+(=), with equals sign used for spare ordering |

Wasn’t sure which model fit our requirements. Their team helped us pick the right one. Would have liked a tracking update sooner, but the product is great.
Internal padding was sufficient to absorb any rough handling during transit.
We got volume pricing without needing to push for it. Minor delay in delivery, but everything was in order.
