Switch SAN Cisco MDS 9148s 16G

1 Product Overview

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:

• Standalone storage area network (SAN) in small departmental storage environments
• Stop-of-the-rack switch in medium-sized redundant fabrics
• Edge switch in enterprise data center core-edge topologies

The Cisco MDS 9148S switch has the following major features:

• 12, 24, and 48, default licensed ports and an 12-port on-demand license
• 2-, 4-, 8- and, 16-Gbps full line rates
• Port interfaces that support field-replaceable, hot-swappable small form-factor pluggable (SFP) transceivers
• Redundant hot-swappable power supplies and fan trays, PortChannels for Inter-Switch Link (ISL) resiliency, and F-port channeling for resiliency on uplinks from a Cisco MDS 9148S operating in NPV mode
• Enterprise class features such as In-Service Software Upgrades (ISSU), Virtual SANs (VSANs), security features, and quality of service (QoS)
• PowerOn Auto Provisioning (POAP) to automate software image upgrades and configuration file installation on newly deployed switches
• Intelligent diagnostics
• Full compatibility with the Cisco MDS 9000 Family.

2 Front View

The front of the Cisco MDS 9148S switch contains the LEDs, the console and management ports, and 48 16-Gbps Fibre Channel Ports

3 Power Supplies

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.

4 Fan Modules

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.

5 Cisco MDS 9148S Multilayer Switch Ports

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.
