N9K-SUP-B Description
N9K-SUP-B is a Cisco Nexus 9500 Supervisor B module for Nexus 9500 modular chassis control-plane and management-plane operation.
This supervisor module uses a 6-core, 12-thread x86 processor with 24GB DRAM and 256GB SSD storage. It is used in Cisco Nexus 9500 chassis environments where the supervisor model, software release, and dual-supervisor redundancy plan must match the installed platform.
Before requesting a quote, confirm the Nexus 9500 chassis, installed supervisor type, NX-OS release, ACI or NX-OS mode, and whether this is a like-for-like replacement or a migration from Supervisor A family hardware.

Application Scenarios
Use N9K-SUP-B when an installed Nexus 9500 chassis already uses Supervisor B modules and needs a like-for-like replacement. The buyer should match the existing supervisor type before quoting a spare.
Choose this module when the chassis requires active-standby supervisor redundancy with Supervisor B modules. Cisco guidance says redundant supervisors should be the same type within a chassis for supported supervisor redundancy.
N9K-SUP-B can be evaluated when a Nexus 9500 environment is moving from the Supervisor A family to the Supervisor B family. Cisco migration guidance should be followed, and the final redundant pair should not mix Supervisor A/A+ with Supervisor B/B+ long term.

- Choose N9K-SUP-B when the installed Nexus 9500 chassis already uses Supervisor B and needs a like-for-like replacement or matched redundant pair.
- Compare N9K-SUP-B+ when the project needs the Supervisor B+ model with 32GB DRAM and the software release supports it.
- Compare Supervisor A or A+ only when matching an existing Supervisor A family chassis; Supervisor A/A+ and Supervisor B/B+ should not be mixed long term.
- Confirm the exact installed supervisor type before ordering, because a mismatched supervisor can prevent supported redundancy.
Selection Guide
1. Choose N9K-SUP-B for Supervisor B continuity
Select N9K-SUP-B when the installed Nexus 9500 system already uses Supervisor B modules and the goal is replacement, sparing, or building a matching redundant supervisor pair.
2. Verify the second supervisor before ordering
For dual-supervisor operation, confirm the installed active or standby supervisor. Cisco guidance says redundant supervisors should be of the same type within a chassis.
3. Check software release and operating mode
Confirm the Cisco NX-OS release, ACI or NX-OS operating mode, and planned supervisor compatibility before ordering. Supervisor B is listed with minimum software support from 6.1(2)I3(1) or later.
4. Use Cisco migration guidance for A-family to B-family changes
If the chassis is moving from Supervisor A or A+ to Supervisor B or B+, follow Cisco migration guidance and quote the final matched supervisor pair rather than leaving a mixed supervisor configuration.
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 family and 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 B requires supported software before deployment |
|
Migration Plan |
Whether the chassis is moving from Supervisor A family to Supervisor B family |
Mixed Supervisor A and B operation is for migration, not a steady-state redundant design |
|
Airflow Direction |
Port-side intake |
Airflow direction must match the Nexus 9500 chassis cooling design |
