DS-C9148T-48PITK9 Description
DS-C9148T-48PITK9 is a Cisco MDS 9148T 32G Fibre Channel SAN switch bundle for adding fixed 32G FC switching at the data center storage edge or server-rack SAN layer. This port-side-intake configuration ships as a 1RU MDS 9148T switch with 48 active Fibre Channel ports, 48 Cisco 32G shortwave FC optics, 4 fans, and 2 power supplies, giving buyers a fully populated 48-port intake-airflow bundle for Cisco MDS 9000 Family SAN deployments.

Product Performance
Key Features
DS-C9148T-48PITK9 combines port-side intake airflow, 48 active FC ports, and 48 Cisco 32G SW optics in one Cisco MDS 9148T order line.
The 48-port bundle arrives with all FC ports active, which separates it from 24-port MDS 9148T orders that rely on M9148T-PL8 growth licenses.
The switch uses the MDS 9148T 48-port SFP+ fixed platform with 4, 8, 16, and 32 Gbps autosensing operation for host, storage, and ISL connectivity.
Cisco documents 3 port groups of 16 ports each, which gives SAN designers a concrete grouping point for distributing hosts, arrays, and port-channel members.
The intake airflow identity should remain aligned across the installed switch, replacement PSUs, and fan modules because Cisco documents separate intake and exhaust spare PIDs.
Cisco lists Cisco MDS NX-OS 8.3(1) or later and Cisco DCNM 11(0) or later as system requirements for the MDS 9148T.
Application Scenarios
DS-C9148T-48PITK9 fits a rack row standardized on port-side intake airflow where the first installation needs every MDS 9148T Fibre Channel port active.
This PID is useful when host and storage cabling is planned around Cisco 32G SW Fibre Channel optics and LC multimode fiber rather than separate media selection.
The SKU suits MDS 9148T refresh work where the approved BOM should land directly on a 48-port active switch instead of a 24-port starter configuration.

- In a DS-C9148T-48PITK9 vs DS-C9148T-48PETK9 comparison, the table difference is airflow direction: DS-C9148T-48PITK9 is port-side intake and DS-C9148T-48PETK9 is port-side exhaust.
- The DS-C9148T-48PITK9 difference from DS-C9148T-24PITK9 is order scale. Both are intake optic bundles, but DS-C9148T-48PITK9 ships with 48 active ports and 48 optics while DS-C9148T-24PITK9 starts with 24 active ports and 24 optics.
- For DS-C9148T-48PITK9 vs DS-C9148T-24IK9, the comparison changes both bundle scope and activation state: DS-C9148T-48PITK9 includes 48 optics and is fully active, while DS-C9148T-24IK9 is an intake base switch with no factory optic bundle.
- Buyers deciding which model to choose should align three confirmed fields before purchase: airflow direction, active-port count, and included optic quantity.
Selection Guide
1. Choose the intake 48-port bundle for a full first shipment
Select DS-C9148T-48PITK9 when the approved SAN map already requires 48 active FC ports, 48 Cisco 32G SW optics, and port-side intake airflow.
2. Use the exhaust twin only for the opposite rack airflow
Move to DS-C9148T-48PETK9 only when the same 48-port optic bundle must use port-side exhaust airflow instead of port-side intake.
3. Keep 24-port orders for staged growth
Choose DS-C9148T-24PITK9 or DS-C9148T-24IK9 only when 24 active ports match the first deployment and future port growth can be handled through documented M9148T-PL8 expansion planning.
4. Separate hardware bundle checks from software entitlements
Confirm Cisco MDS NX-OS 8.3(1) or later, Cisco DCNM 11(0) or later, and any SAN Insights, Enterprise Package, or DCNM Advanced licensing as separate review items.
