4 C H A P T E R Transceiver Modules This chapter tells you where to find instructions for installing SFP modules and X2 modules, which are laser optical transceivers used for Ethernet connections. Where needed, notes applying specifically to these switches are provided. SFP Modules To install SFP Modules, refer to the Cisco Small Form-Factor Pluggable Modules Installation Note at the following location: http://www.cisco.com/en/US/products/hw/modules/ps5455/prod_installation_gu ide09186a00803aa0da.html To get the latest information on SFP compatibility, refer to the relevant documents at the following location: http://www.cisco.com/en/US/products/hw/modules/ps5455/products_device_sup port_tables_list.html SFP Modules and Alternative Wiring The Catalyst 4948 switches have four ports that can be configured with any combination of SFP modules with LC connectors, as shown in Figure 4-2. The interface configuration mode command media-type sfp|rj45 can be used to configure the media type for these ports in the switch software and determines whether the SFP or the RJ-45 connector is used. The default is SFP. 78-18039-02 Catalyst 4900 Series Switch Installation Guide 4-1
