Figure 7-8. Remote RTN Module Hardware Configuration
RTN Mode
The Module Config Switch (S2) is factory configured for RTN mode, expansion rack X1 operation
(address 0x001). The Remote RTN module may be re-configured to as needed to operate as expansion
chassis 1-7.
Note: RTN mode will disable Ethernet ports 1 and 2.
Network Type
The Network Type setting is factory set OFF to automatically configure the RTN communication port IP
addresses to the 172.20.x.x series.
Note: If CAN for GS6 or RTCnet/LINKnet HT operation is required from an expansion rack, a
CPU module must be used in place of the Remote RTN module and configured for an RTN using
the Module Configuration Switch (S2) as shown in section 7.1.3—Module Configuration above.
It is recommended to verify proper switch settings before installing
the module in the system and when troubleshooting RTN related
issues.
The Network Type setting on all CPU and Remote RTN modules in
the system must match for proper system operation.
The customer network attached to Ethernet #1 or #2 at the main
chassis CPUs may already use the RTN port addresses of 172.20.x.x.
In this case, the Network Type switch should be configured ON to
use the alternate 10.250.x.x RTN port addresses.
If the Remote RTN module is incorrectly configured for CPU mode,
Ethernet ports #1 and #2 are active and have been factory-set to fixed
Ethernet IP addresses of:
Ethernet #1 (ENET1) =
172.16.100.1
, Subnet Mask =
255.255.0.0
Ethernet #2 (ENET2) = 192.168.128.20, Subnet Mask =
255.255.255.0
