RF Redundancy Configuration
To make certain that the RF redundancy scheme functions correctly, you must configure
both the APEX1000 and the REM1000.
To begin enabling RF redundancy, use the QAM RF Redundancy window (illustrated in
Figure 6-16) to set the following parameters:
Parameter Values Description
RF Redundancy
• Enabled
• Disabled
Enables port #6 as a backup port,
reserving its QAM channels for
redundancy.
REM1000 communication
mode
• None
• Direct
• Common
Configures the manner by which the
APEX1000 connects to the REM1000
control interface.
APEX1000 ID
• APEX1
• APEX2
Identifies the set of RF inputs on the
REM1000 rear-panel to which the
APEX1000 is connected.
REM1000 IP address
• Valid unicast address in
common mode
or
• Network IP address high byte
in direct mode
OAM&P IP address of REM1000 if
using common hub communication
mode.
Network IP (high byte) of REM1000 if
using direct mode.
Connection Modes
You must first define how the APEX1000s will be connected to the REM1000 by
configuring the REM1000 communication mode parameter through the APEX-EM GUI:
• None – No REM1000 is used.
• Direct – The APEX ENET2 port connects directly to the REM1000 APEX1 or APEX2
port (this is the default setting on the APEX1000, and the recommended
communication mode).
• Common – The APEX communicates over the OAM&P network, using its ENET1
interface to communicate with the REM1000 ENET interface.
CAUTION The APEX prevents you from selecting Direct REM communication mode if ENET2 has
any active mappings, or if UDP port 6060 is already in use on that interface. To enable
Direct mode, you must first clear ENET2 of all mappings.
