Connecting Destination Ports
The auto-MDIX feature is enabled by default. For configuration information for this feature, see the
Cisco IE 4000 Switch Software Configuration Guide .
Connect the other end of the cable to an RJ-45 connector on the other device. The port LED turns on

when both the switch and the connected device have established a link.
The port LED is amber while Spanning Tree Protocol (STP) discovers the topology and searches for
loops. This can take up to 30 seconds, and then the port LED turns green. If the port LED does not turn
on:

Installing and Removing SFP Modules

These sections describe how to install and remove SFP modules. SFP modules are inserted into SFP
module slots on the front of the switch. These field-replaceable modules provide the uplink optical
interfaces, send (TX) and receive (RX).
You can use any combination of rugged SFP modules. See the release notes on Cisco.com for the list of
supported modules. Each SFP module must be of the same type as the SFP module on the other end of
the cable, and the cable must not exceed the stipulated cable length for reliable communications.
When you use commercial SFP modules such as CWDM and 1000BX-U/D, reduce the maximum

operating temperature by 59°F (15°C). The minimum operating temperature is 32°F (0°C).
For detailed instructions on installing, removing, and cabling the SFP module, see your SFP module
documentation.
Do not insert and remove SFP modules while power is on; an electrical arc can occur. This could

cause an explosion in hazardous location installations. Be sure that power is removed or the area
is nonhazardous before proceeding. Statement 1087
