DS-C9148T-48PETK9 Description
DS-C9148T-48PETK9 is a Cisco MDS 9148T 32G Fibre Channel SAN switch bundle for data-center storage fabrics that need fixed 32G FC access with the ports and optics included at order time. The Cisco ordering row identifies this SKU with 48 active FC ports, 48 Cisco 32G shortwave optics, four fans, two power supplies, and port-side exhaust airflow; the platform supports 4/8/16/32 Gbps autosensing Fibre Channel, 1.5 Tbps end-to-end full-duplex aggregate bandwidth, and Cisco MDS NX-OS 8.3(1) or later.

Product Performance
Key Features
The SKU brings the MDS 9148T chassis to 48 active FC ports at purchase time, which is the key distinction from 24-port bundles that require later activation planning.
Cisco ties this PID to 48 included 32G SW Fibre Channel optics, so the switch and day-one multimode 32G optic count stay together in the same hardware quote.
The order is the port-side exhaust version of the 48-port optic bundle. Replacement fan and PSU choices should follow the same exhaust airflow direction.
The platform supports Fibre Channel services such as VSANs, NPV, IVR, port channels, FC-NVMe support, diagnostics, and secure management functions under the required Cisco MDS software release.
The base configuration includes two power supplies and four fan modules, and Cisco lists hot-swappable power, fan, and SFP+ optic components for service planning.
Cisco documents dual out-of-band management ports, NX-API interfaces, onboard Python, SNMPv3, Cisco DCNM integration, and telemetry support for MDS 9148T operations.
Application Scenarios
DS-C9148T-48PETK9 fits SAN refresh work where host, storage, and ISL links already justify all 48 active 32G-capable ports during the first installation window.
The included 48 x 32G SW optic bundle is useful when the design is built around 32G Fibre Channel shortwave links instead of separate longwave or lower-speed optic selection.
Choose this PID for cabinets where cooling design expects exhaust toward the port side. The same airflow identity should stay aligned across the installed switch, spare fans, and spare power supplies.

- In a DS-C9148T-48PETK9 vs DS-C9148T-48PITK9 comparison, both SKUs include 48 active ports and 48 x 32G SW optics, while the difference is exhaust versus intake airflow.
- The DS-C9148T-48PETK9 difference from DS-C9148T-24PETK9 is active-port and optic count: the DS-C9148T-48PETK9 order is fully active with 48 optics and the DS-C9148T-24PETK9 order starts with 24 active ports and 24 optics.
- For DS-C9148T-48PETK9 vs DS-C9148T-24PITK9, the comparison has two checked fields: DS-C9148T-48PETK9 is exhaust with 48 active ports, while DS-C9148T-24PITK9 is intake with 24 active ports.
- Buyers deciding which model to choose should first fix airflow direction, then confirm whether the first order needs the 48-port optic bundle or a 24-port staged start.
Selection Guide
1. Start with the required active-port count
Choose DS-C9148T-48PETK9 when the SAN design needs all 48 FC ports active at delivery. Use a 24-port PET or PIT bundle only when the growth plan is intentionally staged.
2. Match airflow before selecting spares
Select the exhaust SKU when cabinet cooling expects air to leave through the port side. Use the PIT alternative only for racks standardized on port-side intake.
3. Keep the optic bundle tied to the cabling design
This SKU should stay on the BOM when 48 Cisco 32G SW optics match the planned multimode Fibre Channel links. Separate optic lines are still needed for longwave or different-speed links.
4. Separate hardware identity from software entitlements
The switch requires Cisco MDS NX-OS 8.3(1) or later and Cisco DCNM 11(0) or later. Advanced software packages and SAN Insights items should be reviewed as separate entitlement lines.
