shorter copper cables, which can connect to another 40-Gigabit QSFP+ port or four 10-Gigabit SFP+ ports. If the servers or switches are further than 16.4 feet (5 meters), it is best to use the optical cable that has 40-Gigabit transceivers on both ends.

For the Cisco Nexus 3048 switch, you must use RJ-45 connectors on copper cables to make the 10/100/1000 Ethernet downlink connections, and you must use SFP transceivers on copper or optical cables or SFP+ transceivers on optical cables to make the 1- or 10-Gigabit Ethernet uplink connections.

For the Cisco Nexus 3064 switch, you must use RJ-45 connectors on copper cables to make the downlink connections and SFP transceivers on copper or optical cables or SFP+ transceivers on optical cables to make the 1- or 10-Gigabit Ethernet uplink connections.

Installing and Replacing SFP or SFP+ Transceivers

Caution Excessively removing and installing an SFP or SFP+ transceiver can shorten its life. Unless it is absolutely necessary, do not remove and insert SFP or SFP+ transceivers. To prevent damage to an optical cable and transceiver, we recommend that you disconnect cables before installing or removing transceivers.

Installing an SFP or SFP+ Transceiver

To install an SFP or SFP+ transceiver, follow these steps:

Step 1 Attach an ESD-preventive wrist strap and follow its instructions for use.

Step 2 Remove the dust cover from the port cage.

Step 3 Remove the dust cover from the port end of the transceiver.

Step 4 Insert the transceiver into the port as follows:

•If the transceiver has a Mylar tab latch, position the transceiver with the tab on the bottom, and then gently insert the transceiver into the port until it clicks into place.

•If the transceiver has a bale clasp latch, position the transceiver with the clasp on the bottom, close the clasp by pushing it up over the transceiver, and then gently insert the transceiver into the port until it clicks into place.

Caution If the transceiver does not install easily, ensure that it is correctly positioned and the tab or clasp are in the correct position before continuing.
