CFIP PhoeniX HSB mode
1.
Connect each IDU to appropriate ODU. Note that High ODUs should be at one side and Low
ODUs at remote side. Note that for HSB mode ODUs should be interconnected through
coupler at each site.
2.
IDU pairs must be connected as shown in
Figure 4.9
. Note that switches of IDU pair
(‘working’ and ‘protection’) are connected through one of the 1000Base-T user data and
management ports via Ethernet cable, and modems are connected through special extension
port for 1+1 protection via protection cable CAT6 (available from SAF Tehnika P/N S0ACPP1).
3.
Choose same frequencies for ‘working’ and ‘protection’ links.
4.
Before power is supplied to equipment:
-
both IDUs on each side of the link should be grounded;
-
switches of IDUs must be set to correct state. For working link protection mode switch
on CFIP PhoeniX IDU front panel should be set to “1+0” position and for protection
link protection switch should be to “1+1” position as shown in
Figure 4.13
;
-
power protection ports of appropriate units should be interconnected (if available).
5.
Supply the IDUs with power and proceed with configuration.
Configuration for 1+1 Hot Standby Mode
It is possible to perform configuration in Web GUI or through CLI (serial or telnet connection).
For detailed description of commands necessary for 1+1 configuration refer to Chapter 4.3.5.
For 1+1 HSB mode it is necessary to:
•
Assign different IP addresses for each IDU. Note that IP addresses should be within the
same subnet;
•
Set the same frequency pair for working and protection links;
•
Set appropriate state (working/protection) for each IDU;
•
Disable automatic remote IP address identification (set by default) in “Tools
Command
line” with command “modem ipremote off” and set appropriate remote site IP address for
each IDU in “Configuration
IP configuration”: “Remote IP address” for local working IDU
is “IP address” of remote working IDU and “Remote IP address” for local protection IDU is
”IP address” of remote protection IDU;
•
It is recommended that ‘Standby’ and ‘Activetry’ times remain default. IDU will remain in
appropriate state during forcing it to another state for this specified time.
