Managed Storage Fabrics for Data Center Connectivity

DS-C9148T-K9 is a managed 32-Gbps Fiber Channel storage switch with 48 fixed SFP+ ports and 24 ports active in the base configuration. The MDS 9148T connects server HBAs and storage arrays in standalone SANs or at the edge of a larger fabric, rather than providing Ethernet endpoint access. Enabled interfaces carry host, storage, and inter-switch connections without a separate uplink card. FC-NVMe and SCSI workloads can coexist on the same links without a chassis hardware upgrade. The 1U rack-mount design belongs to the Cisco MDS 9100 Series and operates in switch mode or NPV mode when connecting to SAN core directors. DS-C9148T-48PETK9 is the fully activated sibling for orders requiring the entire physical port set at shipment.

Technical Details

1500 Gbps aggregate switching bandwidth supports nonblocking forwarding through the fixed chassis. Port Channels combine as many as 16 physical links for load-balanced fabric connections, while zoning and VSAN isolation separate storage access within the SAN. IVR and traffic encryption require additional Enterprise software entitlements rather than the base feature set. DS-C9148T-K9 runs NX-OS with serial-console and SSHv2 CLI access, SNMPv3 monitoring, and NX-API over HTTPS REST for programmatic control. DCNM provides central management, while onboard Python, EEM, and the software scheduler provide additional automation paths. Four fans provide active cooling, and two AC power supplies provide hot-swappable redundancy. 251W typical consumption with 24 DS-SFP-FC32G-SW transceivers provides a rack power-planning reference for that population; 297W typical consumption with 48 DS-SFP-FC32G-SW transceivers reflects the fully populated case. Size the rack power allocation against the intended transceiver population rather than treating the power supply rating as operating consumption.

Ordering

ORM Systems offers DS-C9148T-K9 new sealed and certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, clean boot, every port linking at rated speed, optics bay recognition, PSU status, and fan status, with firmware verified and configuration wiped to factory default. Select the condition and request a line-item configuration for the purchase order. New units carry up to a 3-year extended ORM warranty, and certified refurbished units carry up to 1 year; returns are 30 days on every condition, terms apply. For enterprise and volume orders, ORM Systems accepts POs, offers Net-30 for government, and provides RMA with advance replacement, with regional stock and RMA support across the UK, EU, US, and MEA.

Buying Notes

Buying NotesKey Specs

Separate software and port licensing

DS-C9148T-K9 orders distinguish perpetual port activation from Advantage or Premier subscriptions, each starting at one year. Include the customer's Cisco Smart Account when adding subscription entitlements; hardware activation and software subscriptions are separate purchases.

Specify optics with the chassis

DS-C9148T-K9 quotes must state transceiver quantities separately from the chassis. Specify DS-SFP-FC32G-SW for 32G shortwave links or DS-SFP-FC32G-LW= for 32G longwave links, matching the selection to the installed fiber.

Software check before deployment

DS-C9148T-K9 requires a software check before deployment because NX-OS 9.4(4) can reload after ungraceful mgmt0 link failures. Exclude the deferred release and require an image correcting CSCws09730.

Best For

Incremental Connection Growth

When host or storage connections outgrow the initially enabled set, additional ports are activated through eight-port entitlements rather than a port card. M9148T-PL8-SL= adds another block, allowing intermediate configurations of 32 or 40 active ports. Specify the required activation level and confirm serial-number authorization before the purchase order.

Airflow Matched Sparing

When a replacement must fit an established rack airflow arrangement, match the power and fan assemblies before shipment. DS-CAC-650W-E= and DS-C32S-FAN-E= serve port-side exhaust configurations; DS-CAC-650W-I= and DS-C32S-FAN-I= serve port-side intake configurations. Record the required airflow and matching spare PIDs on the purchase order.

Buffer Credit Staging

When a SAN design needs concentrated buffer credits on selected connections, size the group allocation rather than multiplying a per-port maximum. A 16-port group supports 8300 credits, with 8270 available to an individual port. Reserve the intended port placement and confirm the credit allocation during staging before finishing the purchase order.

Not Suitable If

64G Fiber Channel links

DS-C9148T-K9 is limited to 32-Gbps Fiber Channel connectivity. DS-C9148V-K9 provides 64G Fiber Channel connectivity for designs that require a higher native link speed.

All ports active without expansion

DS-C9148T-K9 starts with 24 active ports rather than the full physical count. DS-C9148T-48PETK9 provides 48 active ports with DS-SFP-FC32G-SW transceivers and port-side exhaust airflow.

Questions & Answers

What does the DS-C9148T-K9 part number identify?

DS-C9148T-K9 identifies the MDS 9148T 32-Gbps Fiber Channel chassis with 48 physical ports and 24 active ports. The 9148T model designation is distinct from airflow-specific ordering forms: DS-C9148T-24EK9 selects port-side exhaust, and DS-C9148T-24IK9 selects port-side intake. Neither the physical port count nor K9 alone establishes additional port activation entitlements.

How is the MDS 9148T managed?

The MDS 9148T supports serial-console and SSHv2 CLI management, DCNM, SNMPv3, SMI-S, and NX-API over HTTPS REST. SNMPv3 also supports in-band IP over Fiber Channel access. Scriptable CLI, DCNM web services, onboard Python, EEM, and the software scheduler provide automation paths; NDFC management is included in the Advantage and Premier subscription bundles.

Which licensing options apply to DS-C9148T-K9?

DS-C9148T-K9 supports Advantage and Premier subscriptions with one-year minimum terms; port activation remains a separate perpetual entitlement. Advantage includes Enterprise features and NDFC, while Premier adds SAN Analytics. A Cisco Smart Account is required for license ordering, and additional port activation requires an authorization code tied to the switch serial number.

How many active ports does DS-C9148T-K9 include?

DS-C9148T-K9 starts with 24 active Fiber Channel ports and expands to 32, 40, or 48 active ports in eight-port increments. M9148T-PL8-SL= is the spare Smart License for an additional block. Port activation is perpetual, tied to the switch serial number, and requires an authorization code; subscription software does not replace that activation entitlement.

Which transceivers can be ordered for DS-C9148T-K9?

DS-C9148T-K9 supports DS-SFP-FC32G-SW for 32G shortwave links and DS-SFP-FC32G-LW= for 32G longwave links. Lower-speed options include DS-SFP-FC16G-SW and DS-SFP-FC8G-SW=. Match the transceiver speed and fiber requirements to the connected HBA, storage array, or fabric link, and identify the transceiver quantity explicitly on the order.

Does the MDS 9148T have redundant power supplies?

Yes, the MDS 9148T ships with two hot-swappable AC power supplies and four fans, with port-side intake and exhaust configurations available. DS-CAC-650W-I= and DS-CAC-650W-E= are the corresponding spare power supplies. Specify the matching DS-C32S-FAN-I= or DS-C32S-FAN-E= fan assemblies when ordering airflow-specific spares.

Is DS-C9148T-K9 end of sale?

Cisco has not announced an end-of-sale date for MDS 9148T. The DS-C9148T-K9 hardware lifecycle is separate from the lifecycle of an individual NX-OS release. Keep software maintenance planning separate from hardware replacement planning when selecting the switch for an existing SAN or planning additional fabric capacity.

What conditions and warranties does ORM Systems offer for DS-C9148T-K9?

DS-C9148T-K9 is available new sealed with up to a 3-year extended ORM warranty or certified refurbished with up to 1 year of ORM coverage. Returns are available for 30 days on every condition; terms apply. Cisco's hardware warranty is separate from ORM's warranty and commercial returns terms.

What is the difference between DS-C9148T-K9 and DS-C9148T-48PETK9?

DS-C9148T-48PETK9 enables 48 Fiber Channel ports at shipment, whereas DS-C9148T-K9 starts with 24 active ports. Additional activation must be purchased for the base chassis when more connections are needed. Choose the base model for staged port growth and the fully activated bundle when all physical ports must be available from the initial order.

What is the difference between DS-C9148T-K9 and DS-C9148T-24PETK9?

DS-C9148T-24PETK9 bundles 24 DS-SFP-FC32G-SW transceivers with its 24 active ports, while DS-C9148T-K9 is the base chassis identifier rather than that optics-inclusive bundle. The bundle fits an order requiring that shortwave transceiver set; the base identifier allows link-specific optics selection to be specified separately on the purchase order.

What is the difference between DS-C9148T-K9 and DS-C9148V-K9?

DS-C9148V-K9 provides 64G Fiber Channel connectivity, while DS-C9148T-K9 is limited to 32G. The higher native link speed requires different hardware rather than a subscription upgrade to the 32G chassis. An existing 32G SAN requirement matches the MDS 9148T; buyers specifying native 64G connections should select the MDS 9148V.

What power consumption should be used when sizing DS-C9148T-K9?

DS-C9148T-K9 consumes 217W when idle without transceivers; typical consumption is 251W with 24 DS-SFP-FC32G-SW transceivers and 297W with 48 DS-SFP-FC32G-SW transceivers. These figures describe different population and operating conditions, not the supply's rated output. Use the condition matching the planned transceiver population for rack power planning.

Can the MDS 9148T carry NVMe storage traffic?

Yes, the MDS 9148T supports FC-NVMe, and NVMe over Fiber Channel can coexist with SCSI workloads on the same links. The chassis does not require a hardware upgrade for this protocol support. Confirm the host, storage, and transceiver requirements rather than treating protocol support as confirmation of end-to-end component compatibility.

Is DS-C9148T-K9 a 1U rack-mount switch?

Yes, DS-C9148T-K9 is a 1U rack-mount switch measuring 43.7 mm high, 439.42 mm wide, and 566 mm deep, excluding power supply and fan handles. The weight is 8.5 kg. Confirm rack clearance against the chassis depth, cable layout, and selected airflow direction before ordering.
