Overview of Network Connections
After you install the switch in a rack and power it up, you are ready to make the following network connections:
• Console connection—This is a direct local management connection that you use to initially configure
the switch. You must make this connection first to initially configure the switch and determine its IP
address, which is needed for the other connections.
• Management connection—After you complete the initial configuration using a console, you can make
this connection to manage all future switch configurations.
• Uplink and downlink interface connections—These are connections to hosts and servers in the network.
Each of these connection types is explained in one of the sections that follow.
When running cables in overhead or subfloor cable trays, we strongly recommend that you locate power cables
and other potential noise sources as far away as practical from network cabling that terminates on Cisco
equipment. In situations where long parallel cable runs cannot be separated by at least 3.3 feet (1 meter), we
recommend that you shield any potential noise sources by housing them in a grounded metallic conduit.
Note
When using SFP+ or SFP transceivers in a QSFP+ or QSFP28 uplink port, install a QSFP-to-SFP adapter,
such as the CVR-QSFP-SFP10G adapter, in the QSFP port and then install the SFP+ or SFP transceiver. The
switch automatically sets the port speed to the speed of the installed transceiver.
