Extreme Networks ExtremeSwitching SLX 9540 - Precautions Specific to Transceivers and Cables; Cleaning the Fiber-Optic Connectors

FIGURE 33 Optical transceiver extraction tool
Precautions specic to transceivers and cables
DANGER
All ber-optic interfaces use Class 1 lasers.
DANGER
Use only optical transceivers that are qualied by Extreme Networks, Inc. and comply with the FDA Class 1 radiation
performance requirements dened 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 ber-optic connectors
To avoid problems with the connection between the
ber-optic transceiver (SFP+, QSFP, or QSFP28) and the ber 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 ber cable connectors, Extreme recommends using a ber-optic reel-type cleaner. When not using an SFP+ or QSFP
connector, make sure to keep the protective covering in place.
