Overview

The below table identifies the modules supported by the Cisco MDS 9500 Series switches and Cisco MDS 9216A and Cisco MDS 9216i switches, as well as the Generation 2 switches:

Table 5-1 Generation 2 Modules and Switches

Part Number

Description

Modules

DS-X9148

48-port 4-Gbps Fibre Channel switching module

DS-9304-18K9

18-port 1/2/4-Gbps Fibre Channel switching module with 4 Gigabit Ethernet ports

DS-X9112

12-port 4-Gbps Fibre Channel switching module

DS-X9704

4-port 10-Gbps Fibre Channel switching module

DS-X9530-SF2-K9

Supervisor-2 module (Cisco MDS 9500 Series switches only)

Switches

DS-C9222i-K9

10-port 4-Gbps Fibre Channel switch with 4 Gigabit Ethernet IP storage services ports, and a modular expansion slot to host Cisco MDS 9000 Family Switching and Services Modules

DS-9134-K9

34-port 4-Gbps Fibre Channel switch

DS-X9124

24-port 4-Gbps Fibre Channel switch

DS-9304-K9

18-port 1/2/4-Gbps Fibre Channel switch with 4 Gigabit Ethernet ports in fixed slot1

Note Note: Generation 2 Fibre Channel switching modules are not supported on the Cisco MDS 9216 switch; however, they are supported by both the Supervisor-1 module and the Supervisor-2 module.

The 4-port 10-Gbps Fibre Channel switching module supports 10-Gbps port rates. The rest of the Generation 2 modules support 1-Gbps, 2-Gbps, 4-Gbps, or autosensing port rates.

For detailed information about the installation and specifications for these modules, refer to the hardware installation guide or the Configuration guides at the following website:

Port Groups

Each module has four groups of one or more ports in port groups that share common resources, such as bandwidth and buffer credits. The table below shows the port groups for the Generation 2 Fibre Channel switches and modules.
