Table 2-10 lists the maximum transmission distances for console port cables.
See Appendix A, “Technical Specifications” for console port and cable pinout
information.
Port Connector Requirements—Switching Modules Only
You need these connector types to cable to the switching ports:
• SC connectors for GBICs. (See Figure 2-4.)
Note When you plug the SC connector into the GBIC, make sure that both
the Tx and Rx fiber-optic cables are fully inserted into the SC
connector.
Note If you are using the LX/LH GBIC with MMF, you need to install a
patch cord between the GBIC and the MMF cable. See the “Patch
Cord” section on page 2-9 for details.
• RJ-45 male connectors for the 48-port 10/100BASE-T RJ-45 module. (See
Figure 2-5.)
