Chapter 4 Provisioning
Provisioning the Ethernet Ports
with two IOC cards, one card is active and drives outputs, while the other is in
standby mode. Both cards share the same configuration, which is IOC1. Neither
card is primary. Switching is non-revertive. The configuration and state is
synchronized between cards automatically. See Parameters with IOC Card
Redundancy, on page 483 for a thorough description of IP addresses, MAC
addresses, and Clock IDs.
On system power-up, IOC1 will be active. After initial warm-up, the Rb IOC (in a
mixed Rb IOC, Qtz IOC-card configuration) will be active. If the active IOC card fails
or loses its Ethernet connection, the TP5000 will switch over to the standby card
within 10 seconds. The active IOC card sends a gratuitous ARP after switchover.
Manual switchover is also supported. See Causes of Switchovers Between IOC
Cards, on page 485 for a thorough description of TP5000 behavior with redundant
IOC cards.
