NOTE
(1) Before accessing the base station through the ETH port, ensure that an OM port has been opened and
the user has obtained required authorities for accessing the base station through the OM port.
(2) The TST port is used for commissioning the base station rather than importing or exporting the base
station configuration.
(3) The security of the USB port is ensured by encryption.
NOTE
SFP0 and FE/GE0 ports on the LMPT are used for one GE input. Therefore, they are not used
simultaneously.
SFP1 and FE/GE1 ports on the LMPT are used for another GE input. Therefore, they cannot be used
simultaneously.
