4.2 Fiber Optic Connections
Optional 100G QSFP28 transceivers can be used for fiber connections from the switch to
other network devices in the data center. A QSFP28 transceiver may also be used for long
distance connections to devices at another site.
WARNING:
• When selecting a fiber QSFP28 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 QSFP28 transceiver.
The following figure illustrates the QSFP28 port fiber connection.

4.3 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
