Dual Node Configurations
Boot is used to indicate the primary connection. There is one Ethernet connection from both engine_1 and engine_2. Standby is provided as a backup connection in the event of a network failure to provide an alternate network path.
The diagrams below show the connections to be made from each engine (P5 520) to the customer’s pair of 10/100 or gigabit Ethernet switches.
For connecting to a gigabit Ethernet network, the boot (primary) connections are made from the first port of the 2 Port Gigabit Ethernet SX
XAdapter installed on engine_1 and engine_2 to the customer’s gigabit Ethernet switch (Switch2). Switch2 will carry the network traffic to the DR550 when there is a network failure associated with connections to Switch1. All gigabit Ethernet connections are to use fiber optic cabling.
