Destination IP Address
After defining the communication mode parameters, you must define the correct
destination IP address (es).
Direct Mode Configuration
If an APEX1000 connects to the REM1000 through the direct interface, the APEX and
REM must verify that the REM's APEX1 and APEX2 FastE interfaces are on the same
network as the APEX1000's ENET2 port.
•
The high-byte of the interface IP address value is configurable to avoid collisions with
the ENET1 port IP address. The default value on both the APEX and the REM is 51.
•
You must ensure that the APEX is configured with the same IP high-byte as
configured on the REM if direct mode is used.
Refer to the REM1000 Installation and Operation Guide (Motorola part # 559607-001) for
additional information.
Common Mode Configuration
If the APEX connects to the REM through the OAM&P network (Common Mode is
used), you must configure the APEX1000 with the correct REM1000 IP address.
APEX Device ID
Each REM1000 supports a maximum of two APEX1000s. The APEX ID parameter pairs
an APEX with a set of RF inputs.
You must configure the device ID of the APEX1000 according to the set of RF inputs to
which it is connected on the REM1000, and make certain that the APEX ID corresponds
to the set of connected inputs on the REM1000.
APEX1000 RF Failure Modes
The following RF failures are detected by the APEX1000 (with an SNMP trap issued for
each occurrence):
•
QAM Channel Fault — A single QAM channel has failed on the RF port.
•
QAM RF Port Fault — A single RF port has failed, and all QAMs (up to 8) on that
port are unavailable.
•
QAM Module Fault — A QAM module (RFPM) has failed. Both RF ports are
unavailable.
During a critical error on a channel, port, or module, the APEX1000 will failover to the
redundant port. A critical error indicates that a QAM channel was active when the APEX
detected the fault.
CAUTION
If there is a critical error on the redundant port or a major REM1000 error, the APEX
cannot support RF redundancy, and failover will not occur.
