Before to continue, read carefully the following safety warnings:
Prior to installation carefully read the whole guide.
Pay attention to the safety instructions during installation, operation or
maintenance of this product. Installation, adjustments or maintenance
must be performed only by qualified, trained and authorized personnel.
To prevent the risk of electrical shocks, before turning the equipment on
or connecting an interface card or cable, install the protective grounding
system.
Before connecting any cable to the equipment, make sure that the
grounding system is functional.
Optical Transceivers used in DM4270 have invisible LASER emitting.
Although all DATACOM homologated transceivers and most of the market
transceivers comply with LASER safety standards, avoid direct contact
and exposure to eyes and skin.
The optical modules use invisible radiation laser transmitters. Although
most SFP/SFP+/QSFP+/QSFP28 on the market meet LASER safety
specifications, never look directly at the terminals of a module or an
optical cord. Exposure to laser emissions may cause partial or total loss
of vision.
