Precautions specific to transceivers and cables
Warning
All fiber-optic interfaces use Class 1 lasers.
Warning
Use only optical transceivers that are qualified by Extreme Networks, Inc. and comply with the
FDA Class 1 radiation performance requirements defined in 21 CFR Subchapter I, and with IEC
60825 and EN60825. Optical products that do not comply with these standards might emit
light that is hazardous to the eyes.
Caution
Do not use the port cover tabs to lift the module. They are not designed to support the weight
of the module, which can fall and be damaged.
Caution
Before plugging a cable into any port, be sure to discharge the voltage stored on the cable by
touching the electrical contacts to ground surface.
Cleaning the fiber-optic connectors
To avoid problems with the connection between the fiber-optic transceiver (SFP+, QSFP, or QSFP28)
and the fiber cable connectors, Extreme strongly recommends cleaning both connectors each time you
disconnect and reconnect them. Dust can accumulate on the connectors and cause problems such as
reducing the optic launch power.
To clean the fiber cable connectors, Extreme recommends using a fiber-optic reel-type cleaner. When
not using an SFP+ or QSFP connector, make sure to keep the protective covering in place.
Managing cables
The minimum radius that a 50 micron cable can be bent under full tensile load is 5.1 cm (2 in.). For a
cable under no tensile load, that minimum is 3.0 cm (1.2 in.). Cables can be organized and managed in a
