Chapter 3: 9150 Main Configuration
Redundancy
Backup IP Address
The Backup IP Address parameter contains the address of the other 9150 with which
this 9150 communicates. The default value is 0.0.0.0.
Note: The Backup IP address cannot be the same as the Alias IP address
(page 46).
Poll Interval, Poll Timeout And Poll Tries Parameters
The next three parameters are closely related. When this 9150 acts as the secondary
device, it polls the primary 9150 at intervals specified by the Poll Interval parameter.
After each poll, this 9150 waits for a reply for the length of time specified by the
Poll Timeout parameter. If there is no reply during this time period, the 9150 sends
another poll to the other 9150. The total number of polls sent while this 9150 waits
for the response is specified by the Poll Tries parameter. If no response is received to
the polls, the 9150 then pings the arbiter(s) to determine the status of the network.
Poll I nt er va l
This parameter contains the interval, in seconds, at which this 9150 communicates

Poll Timeout
This parameter contains the interval, in seconds, during which this 9150 waits for a
reply after sending a poll to the other 9150. If there is no reply, it sends another poll
to the other 9150.

Poll Tries
This parameter contains the number of times this 9150 will re-send a poll to the
other 9150, before assuming that it cannot be reached.
The usable range of values is 2 to 7, the default is 3. The value can go as high as 9.
