Controller Cluster I/O Ports
Controller cluster interface cards provide redundant links through I/O ports that enable two
controllers to communicate with each other. For the location of these cluster interface cards, see
the hardware overview for the appropriate controller.
ZS9-2 controllers employ Ethernet-based clustering using two Ethernet ports in the Oracle
Quad Port 10GBASE-T Ethernet Adapter. All other controller cluster interface cards employ
serial-based clustering using two serial cluster links, and provide Ethernet connectivity via one
link.
For all controllers, the LEDs for the cluster ports have the following meanings. Note that for
serial cluster ports, only one of the LEDs (the link status LED) is used. For Ethernet ports, both
LEDs are used. See the following figures.
Activity LED

Flashing green: Data activity
Link Status LED

Solid green: Normal connection
■
Solid yellow or off: Degraded connection
The following diagram illustrates the cluster Ethernet ports for ZS9-2 controllers.
