Motorola APEX1000 Installation And Operation Manual page 130

Note that when you enable RF Redundancy, you will no longer be able to select RF Port
6 and all channels on Port 6 on several screens, because it is reserved as the secondary
(backup) port.
CAUTION APEX1000 RF redundancy is configured primarily through the REM1000 Console Port.
For further information, reference the REM1000 Installation and Operation Guide
(Motorola part number 559607-001).

QAM RF Redundancy window field definitions
Definition/Range
Use to enable or disable RF redundancy mode. (Enabling RF Redundancy allows the
APEX to failover to the backup RF port and communicate with the REM1000.)
RF Redundancy cannot be enabled if:
1. The backup port (RF Port 6) is not present (there is no QAM Module in QAM slot 3).
2. There are any mappings to any QAM Channel on the backup port. RF Port 6, QAM
Channels 6A to 6H (Output Transport Streams 41 to 48).
3. If there are any DTA mappings on Channels 6A to 6H.
Redundancy Configuration
Configures how the APEX is connected to the REM1000.
Available network topologies:
•
None – Not connecting to REM1000.
•
Direct – Connected to the REM1000's dedicated IP interface through APEX Data IP
(Enet2). Broadcast connection is always used in this case. You cannot set to Direct if
the RF Redundancy UDP Port is in use on the Data IP Port Enet2.
•
Common – Connected to REM1000's OAM&P interface through APEX OAM&P IP
Enet 1. Requires you to configure the REM1000 IP address, and cannot be set to
Common if the QAM RF Redundancy UDP Port is in use on the OA&P IP (Enet 1).
Notes:
1. Because IP-related configuration is automatic, Direct mode is typically used. Using the
Element Manager (EM), you only need to designate the configuration mode (Direct
Mode) and configure the associated APEX Identifier (APEX1 or APEX2).
2. Because there is no additional network device (such as a hub or switch) to connect
through, you can achieve greater reliability with Direct mode. This setting cannot be
changed when the backup port is active.
Indicates the current connection between the APEXs and the REM.
Depending on the current status, one of the following values will display:
•
Not Applicable – QAM RF Redundancy is not enabled and/or the connection to the
REM is not enabled.
•
Not Connected – This is the initial condition. The APEX has not yet sent a switch port
message.
•
Connected – Received ack message from the REM for current switch port message.
•
Connection Lost – The REM has not replied to the last three switch port messages.
