WARNING
The optical interfaces on the equipment or the cables, which are not used, must be covered
with protective caps.
When removing the cable that connects to the optical interface on the equipment, cover the
optical interface on the equipment and the cable with protective caps.
When you perform the hardware loopback test by connecting the cable to the optical
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 equipment and the local equipment to avoid damage to the optical
module as a result of strong optical power.
Do not remove or insert the optical interfaces connecting to cables at will.
