Chapter 1 Product Overview Switching Modules The Fibre Channel switching modules provide system-wide power management and autonegotiation, which allows ports to negotiate for speed at the other end of the link. Each module has temperature sensors and an EEPROM that stores serial number and model number information. The Fibre Channel port interfaces support hot-swappable Fibre Channel SFP transceivers that can be short wavelength (SWL) or long wavelength (LWL). The port interfaces also support coarse wavelength-division multiplexing (CWDM) SFP transceivers, which can be used for extended long wavelength (ELWL) transmission or for CWDM. See the "Supported Transceivers" section on page 1-35. Note The internal bootflash installed on the modules are not field-replaceable units. Do not remove or replace internal bootflash on the modules. Modifying the factory-installed bootflash is not supported. 48-Port 4-Gbps Fibre Channel Switching Module The 48-port 4-Gbps Fibre Channel switching module offers 48 autosensing 1-, 2-, and 4-Gbps Fibre Channel ports and can be used in any of the Cisco MDS 9500 Series chassis and in the Cisco MDS 9222i, 9216i, and 9216A Switches. The 48-port switching module can be configured in one of two operational modes: shared bandwidth mode (default) and dedicated bandwidth mode. Figure 1-8 shows a 48-port 4-Gbps Fibre Channel switching module. The front panel connectors are standard modular SFP and the speed detection is autosensing.
