CHAPTER 3 | Making Network Connections
Fiber Optic Connections
FIBER OPTIC CONNECTIONS
Optional 10G SFP+ or 40G QSFP transceivers can be used for fiber connections from the
switch to other network devices in the data center. An SFP+ transceiver may also be used
for long distance connections to devices at another site.
The following figure illustrates the SFP+/QSFP port fiber connection.

ETHERNET CABLING
To ensure proper operation when installing the switch into a network, make sure that the
current cables are suitable for 10BASE-T, 100BASE-TX or 1000BASE-T operation. Check
the following criteria against the current installation of your network:
Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables with
RJ-45 connectors; Category 3 or better for 10BASE-T, Category 5 or better for
100BASE-TX, and Category 5, 5e or 6 for 1000BASE-T.
Protection from radio frequency interference emissions
Electrical surge suppression
Separation of electrical wires (switch related or other) and electromagnetic fields from
data based network wiring
Safe connections with no damaged cables, connectors or shields
WARNING: This switch uses lasers to transmit signals over fiber optic cable. The
lasers are compliant with the requirements of a Class 1 Laser Product and are inher-
ently eye safe in normal operation. However, you should never look directly at a trans-
mit port when it is powered on.
WARNING: When selecting a fiber SFP+/QSFP device, considering safety, please
make sure that it can function at a temperature that is not less than the recommended
maximum operational temperature of the product. You must also use an approved
Laser Class 1 SFP transceiver.
