DS3 N+1 Cable Assembly:

Two DS3 Cable assemblies are needed to connect one Primary DS3 IMG 1010 to one Backup DS3 IMG 1010. One assembly for Transmit and one assembly for Receive. The DS3 Cable assemblies must be connected as shown in the diagram above. Always use the supplied cable assemblies when connecting the DS3 Primary and a DS3 Backup nodes. Using cables other than the supplied cables could result in noise being introduced into the system and/or damage to DS3 connectors on IMG 1010 resulting in intermittent operation. See Below.
