DS-C9148T-24PITK9 Description
DS-C9148T-24PITK9 is a Cisco MDS 9148T 32G Fibre Channel SAN switch bundle for data center storage fabrics that need 32G server and storage connectivity with a defined starting port count. The bundle is based on the 1RU MDS 9148T fixed switch platform with 48 SFP+ Fibre Channel ports, 24 active FC ports at order, 24 included 32G shortwave optics, port-side intake airflow, 4 fans, 2 power supplies, and Cisco MDS NX-OS 8.3(1) or later support, giving buyers a preconfigured 24-port SAN switch that can expand through 8-port activation licenses when additional Fibre Channel capacity is required.

Product Performance
Key Features
DS-C9148T-24PITK9 combines port-side intake airflow with 24 active FC ports and 24 Cisco 32G SW optics, reducing the chance that the first optic set is missed as a separate BOM line.
The hardware platform has 48 SFP+ FC ports, while this order activates 24 ports at shipment and leaves later 32, 40, or 48-port activation to M9148T-PL8 license planning.
Cisco documents 4, 8, 16, and 32 Gbps autosensing Fibre Channel operation with 32 Gbps of dedicated bandwidth per port for host, array, and ISL mapping.
Port-side intake airflow means replacement PSUs and fan modules should use the intake spare PIDs listed by Cisco, and the rack airflow plan should match front-to-back cooling.
The MDS 9148T feature set includes VSAN, NPV, IVR, port channels, flow- and zone-based QoS, FC-NVMe protocol support, and SAN diagnostics under the Cisco MDS software baseline.
Cisco lists out-of-band management ports, RS-232 console access, USB power-on auto-provisioning, SNMPv3, NX-API REST interfaces, Cisco DCNM support, and onboard Python for operations planning.
Application Scenarios
Use DS-C9148T-24PITK9 when the fabric refresh needs 24 active Fibre Channel ports and the matching first set of Cisco 32G shortwave optics in the same intake-airflow switch order.
This SKU fits projects using shortwave Fibre Channel media where the cabling plan is built around LC multimode runs and 32G host or storage endpoints.
DS-C9148T-24PITK9 is appropriate when the cabinet cooling design expects air to enter from the port side and exhaust through the rear of the chassis.

- In a DS-C9148T-24PITK9 vs DS-C9148T-24PETK9 comparison, the confirmed difference is airflow: DS-C9148T-24PITK9 is port-side intake and DS-C9148T-24PETK9 is port-side exhaust.
- The DS-C9148T-24PITK9 difference from DS-C9148T-24IK9 is the included optic bundle. DS-C9148T-24PITK9 includes 24 Cisco 32G SW optics, while DS-C9148T-24IK9 is the intake base order without factory optics.
- For DS-C9148T-24PITK9 vs DS-C9148T-48PITK9, the comparison changes from 24 active ports and 24 included optics to 48 active ports and 48 included optics.
- Buyers deciding which model to choose should match three table facts to the BOM: airflow direction, active-port count at deployment, and whether Cisco 32G SW optics are included.
Selection Guide
1. Select this SKU for an intake 24-port optic bundle
Choose DS-C9148T-24PITK9 when the project needs port-side intake airflow, 24 active FC ports, and 24 bundled 32G SW optics on the first order.
2. Use the non-optic intake base only when media is separate
Select DS-C9148T-24IK9 instead when the chassis should be ordered with intake airflow but the optic type, quantity, or reach must stay outside the switch bundle.
3. Move to the 48-port bundle for full activation at shipment
Use DS-C9148T-48PITK9 when the SAN map requires 48 active ports and 48 included 32G SW optics immediately, rather than later activation through M9148T-PL8 licenses.
4. Keep airflow spares and software in the same review
Verify intake PSU and fan spare PIDs, Cisco MDS NX-OS 8.3(1) or later, Cisco DCNM 11(0) or later, and regional power cords before the quote is finalized.
Ordering Checklist

Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact bundle PID |
DS-C9148T-24PITK9 with 24 active ports and 24 32G SW optics |
Separates the intake optic bundle from base and exhaust variants |
|
Airflow direction |
Port-side intake chassis, fans, and PSUs |
Keeps rack cooling and future replacement parts aligned |
|
Fiber and optic match |
DS-SFP-FC32G-SW shortwave optics with LC multimode cabling |
Avoids ordering a shortwave bundle for a longwave or single-mode link plan |
|
Port growth |
M9148T-PL8 licensing for 32, 40, or 48 active ports |
Prevents a later expansion from being treated as already active |
|
Software floor |
Cisco MDS NX-OS 8.3(1) or later and Cisco DCNM 11(0) or later |
Confirms the deployment baseline before staging |
|
Power cords |
Region-specific C15 or cabinet jumper power cords |
Prevents installation delay when the switch arrives |

Been ordering from Layer23 for multiple projects now. Reliable partner.
Reviews don’t lie. Layer23 is everything people say it is.
Reliable shipping every time. We can plan around their lead times confidently.
It’s a trap… if you don’t check airflow direction! But this unit is correct. Cool air in from ports.
(Sullustan chatter) – Good equipment. Fast ship.
