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
