Appendix B Installation In a Hazardous Environment
Connecting Destination Ports
Caution Do not remove the rubber plugs from the SFP module port or the rubber caps from the fiber-optic cable
until you are ready to connect the cable. The plugs and caps protect the SFP module ports and cables
from contamination and ambient light.
Before connecting to the SFP module, be sure that you understand the port and cabling stipulations in
the
“Preparing for Installation” section on page B-1. See Appendix C, “Cable and Connectors,” for
information about the LC on the SFP module.
To connect to a dual-purpose port, follow these steps:
Step 1 Connect an RJ-45 connector to the 10/100/1000 port, or install an SFP module into the SFP module slot,
and connect a cable to the SFP module port. See
Figure B-36.
For more information about RJ-45 connections, SFP modules, and optical connections, see the
“Connecting to 10/100 and 10/100/1000 Ports” section on page B-41, the “Installing and Removing SFP
Modules” section on page B-42, and the “Connecting to SFP Modules” section on page B-45.

Step 2 Connect the other end of the cable to the other device.
By default, the switch detects whether an RJ-45 connector or SFP module is connected to a dual-purpose
port and configures the port accordingly. You can change this setting and configure the port to recognize
only an RJ-45 connector or only an SFP module by using the media type interface configuration
command. For more information, see the switch command reference.
