N9K-X9788TC-FX Description
N9K-X9788TC-FX is a Cisco Nexus 9500 Cloud Scale line card that combines 48 100M/1/10G BASE-T access ports with four 40/100G QSFP28 aggregation ports for Nexus 9500 modular chassis deployments.
The buying distinction from N9K-X97160YC-EX is media and access-speed coverage: N9K-X9788TC-FX is the BaseT copper option with MACSec listed, while N9K-X97160YC-EX uses SFP+ access ports for 1/10/25G fiber-oriented designs. Treat the order as a cabling and port-media decision before comparing price.
Quote review should verify the Nexus 9504, Nexus 9508, or Nexus 9516 chassis, NX-OS mode, fabric module family, port-side intake airflow, BaseT cabling plan, QSFP28 optics, and any software or optics matrix requirements for 40/100G links.

Application Scenarios
N9K-X9788TC-FX fits a Nexus 9500 modular chassis where the access-side cabling plan calls for copper BASE-T ports instead of SFP+ access ports. The four QSFP28 ports keep 40/100G aggregation available on the same line card.
This line card is relevant when the chassis is running Cisco NX-OS and the BOM needs both dense 1/10G BaseT access and a small set of 40/100G QSFP28 aggregation ports. It should not be treated as an ACI-spine card because Cisco lists ACI spine support as No for X9788TC-FX.
N9K-X9788TC-FX can be selected with Nexus 9500 cloud-scale line cards that use a four-fabric maximum-bandwidth plan. The order should also account for Cisco hardware-guide rules on same-type fabric modules and the chassis-specific line-card slot count.

- In a N9K-X9788TC-FX vs N9K-X97160YC-EX comparison, the core difference is access media: N9K-X9788TC-FX uses 48 BASE-T copper access ports, while N9K-X97160YC-EX uses 48 SFP+ access ports with 1/10/25G support.
- The N9K-X9788TC-FX difference from N9K-X9732C-FX is port mix and fabric redundancy: N9K-X9788TC-FX combines copper BaseT with four QSFP28 ports and has no N+1 fabric module redundancy listed, while N9K-X9732C-FX is a 32-port 100G QSFP28 line card with a five-fabric N+1 option in homogeneous chassis designs.
- For buyers deciding which model to choose, the comparison should start with cabling media, 100G port density, MACSec requirement, and whether the Nexus 9500 fabric plan already supports the selected line-card family.
Selection Guide
1. Choose N9K-X9788TC-FX for BaseT access plus QSFP aggregation
Select N9K-X9788TC-FX when the Nexus 9500 chassis needs 48 copper 100M/1/10G BASE-T ports and four 40/100G QSFP28 ports on the same cloud-scale line card.
2. Move to N9K-X97160YC-EX for SFP+ access designs
Compare N9K-X97160YC-EX when the access-side design is built around SFP+ media and 1/10/25G access ports instead of copper BASE-T cabling.
3. Use N9K-X9732C-FX for higher 100G QSFP28 density
Choose N9K-X9732C-FX when the order needs 32 100G QSFP28 ports and the chassis design can take advantage of its listed N+1 fabric module redundancy option.
4. Verify chassis mode and fabric details before quote approval
Confirm NX-OS mode, same-type fabric modules, line-card slot capacity, port-side intake airflow, and QSFP28 optics support before finalizing the bill of materials.

|
Fabric plan |
Four cloud-scale fabric modules for maximum bandwidth |
The data sheet lists four fabric modules for maximum bandwidth on X9788TC-FX |
|
Fabric module type |
Same-type fabric modules across the chassis |
Cisco hardware guides state that modular-switch fabric modules must match |
|
Port media |
BASE-T access cabling plus QSFP28 40/100G optics |
Avoids ordering a copper access line card for a fiber-only access design |
|
Chassis quantity |
Up to 4 in Nexus 9504, 8 in Nexus 9508, or 16 in Nexus 9516 |
Aligns the line-card count with Cisco release-note maximum quantities |
