CAUTION - ELECTROSTATIC DISCHARGE (ESD)
Prevent electrostatic discharge damages to internal electronic
parts by discharging your body to a grounding point (e.g. use a
wrist strap).
CAUTION - HANDLING OF SFP TRANSCEIVERS
SFP transceivers are supplied with plugs to avoid contamination
inside the optical port. They are very sensitive to dust and dirt. If
the fibre is disconnected from the product, the protective plugs
on the transmitter/receiver must be connected. The protective
plugs must be kept on during transportation. The fibre optics
cables must be handled the same way.
