Note: Most devices come with a transceiver extraction tool and holster. The extraction tool is designed
to remove transceivers from modules where the space is limited.

Precautions specific to transceivers and cables
CAUTION:
All fiber-optic interfaces use Class 1 lasers.
CAUTION:
Use only optical transceivers that are qualified by IBM and comply with the FDA Class 1
radiation performance requirements defined in 21 CFR Subchapter I, and with IEC 825
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.
18-32 kg (39.7-70.5 lbs)
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+ or QSFP) and the fiber
cable connectors, IBM 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.
A fiber-optic reel-type cleaner is recommended for cleaning the fiber cable connectors. When not using an
SFP+, or QSFP connector, make sure to keep the protective covering in place.
