The Cisco MDS 9148S Multilayer Fabric Switch (DS-C9148S48PK9) is the next generation of the highly reliable and flexible Cisco MDS 9100 Series switches. A powerful compact one rack-unit (1RU) form factor can scale from 12 to 48 line-rate 16-Gbps Fibre Channel ports.
The Cisco MDS 9148S switch meets the requirements for a:
The Cisco MDS 9148S switch has the following major features:
This section describes the different views of the chassis.
The front of the Cisco MDS 9148S switch contains the LEDs, the console and management ports, and 48 16-Gbps Fibre Channel Ports. See Figure 1.

This chapter describes hardware information about the Cisco MDS 9148S switch and its components, and it includes the following sections:
The Cisco MDS 9148S switch supports only AC power supplies. Each power supply provides sufficient power to maintain switch operation in the event of a single power supply failure. Power supplies are hot swappable and can be individually replaced without disruption to the system.
The power supply has two LEDs, INPUT OK and OUTPUT OK. Power supply status is also indicated on a front panel LED.
Procedures for replacing and installing the power supplies are available in the Removing and Installing AC Power Supplies section.
The Cisco MDS 9148S switch supports two hot-swappable fan modules that allow the switches to continue to run if a fan module is removed, provided that the preset temperature thresholds have not been exceeded. You can swap out a fan module without having to bring the system down. Each fan module on the Cisco MDS 9148S switch has two fans.
Procedures for replacing and installing the fan modules are available in the Removing and Installing Fan Modules section.
The Cisco MDS 9148S switch provides host, target, and Inter-Switch Link (ISL) connectivity. It provides up to 48 autosensing and autonegotiating Fibre Channel ports capable of speeds of 2-, 4-, 8-, and 16-Gbps. The first 12 ports are licensed by default. On-Demand Port Activation Licensing allows expansion up to 48 ports, with additional ports available as an 12-port group.
The following types of SFP+ transceivers are available from Cisco Systems and are supported on the Cisco MDS 9148S switch:
SFP transceivers are field-replaceable. You can use any combination of SFP transceivers that are supported by the switch. The only restrictions are that SW transceivers must be paired with SW transceivers, and LW transceivers with LW transceivers, and the cable must not exceed the stipulated cable length for reliable communications.
For the list of supported SFP transceivers, see the Cisco MDS 9000 Family Release Notes for Cisco MDS NX-OS Releases. For more information about a specific Cisco SFP transceiver, see the “SFP Transceiver Specifications”. SFP transceivers can be ordered separately or with the Cisco MDS 9148S Switch.
Note Use only Cisco SFP transceivers on the Cisco MDS 9148S switches. Each Cisco SFP transceiver is encoded with model information that enables the switch to verify that the SFP transceiver meets the requirements for the switch.
