2.3 Adding or Removing a Traffic Modem to/from an Operating
CRS-500 1:N Redundancy System
If adding a Traffic Modem to or removing a Traffic Modem from an operating
CRS-500 1:N Redundancy System, take care not to interfere with the existing
traffic. Make sure to correctly perform the cabling and power-up or power-down
sequences. Do not allow the modem Tx carrier to cause contention in the system.

Reference
1 Unpack and inspect the modem. 3
2 Install the modem into the rack* at its desired location. 3
3 Connect cables between the powered OFF modem and the CRS-500 1:N
Redundancy System components (CRS-500 CSU/DSU/ ISU(s), existing modems)
and equipment * (excluding the Upconverter *).
4
4 Configure the modem for use in the CRS-500 1:N Redundancy System. Typical for
each added modem:
6
Power ON the modem. 5
Verify that the modem is running its most recent firmware version, and that all
other modems in the system are running this same firmware version.
5
Enable Redundancy Mode. 6
Set IP Address (for M&C to/from the CRS-500). 6
Configure PMSI (if Carrier-in-Carrier [CnC] is used). 6
5 Configure the CRS-500 CSU for 1:N Operation with the new modem: 7
Set Operating mode to Manual Switching mode. 7
Set IP address (for M&C to/from modems) 7
Set Redundancy Traffic IP address (if applicable) 7
Activate the new Traffic Modem. 7
Perform Redundancy System Checkout. 2
Set Operating Mode to Auto Switching Mode. 7
6 Connect RF* cables between either the CRS-500 ISU(s) or the signal combiners,
and the RF Upconverters *.
4
DO NOT CONNECT the IF to any Upconverters UNTIL AFTER the CRS-500 1:N Redundancy
System is fully cabled and configured. Do this to prevent unintended signals from reaching the
satellite.
