Since an ESD-preventive wrist strap prevents only the static electricity of your body, you
need to wear an ESD-preventive coat to prevent the static electricity of the clothes.
Wear the ESD-preventive wrist strap, ESD-preventive gloves and ESD-preventive clothes
before installing or replacing the device. Otherwise, the static electricity of your body might
damage the ESSDs on the circuit board.
Use special ESD-preventive bags to carry or transport the parts.

WARNING
The fiber channel (FC) interfaces on the device or the cables, which are not used, must be
covered with protective caps.
When removing the cable that connects to the FC interface on the device, cover the FC
interface on the device and the cable with protective caps.
When you perform the hardware loopback test by connecting the cable to the FC interface,
you must add an attenuator to avoid damage to the optical module as a result of strong
optical power.
When using the Optical Time Domain Reflectometer (OTDR), you need to disconnect the
cable between the peer device and the local device to avoid damage to the optical module
as a result of strong optical power.
Do not remove or insert the FC interfaces connecting to cables at will.
