Add IP Address to AutoPing
Use this option to specify the address of an IP device you
wish to monitor. After entering the IP address, the settings
page will refresh and you can select the outlets associated
with this address. Use the checkboxes in the AutoPing
section to correlate the IP address to one or more outlets. If
communications to the target IP is lost, these outlets will be
rebooted. Four main parameters control AutoPing:
Time between pings
This is the time between each "ping" check of the IP address. 60
seconds should be useful for most applications.
Ping failures before reboot
This sets the number of failed communications attempts that
must be sequentially detected before a power cycle. For
example, when set to 5, the target system must fail to respond
5 times in a row before it is rebooted. Since occasional network
timeouts and packet loss can occur during normal Ethernet
operation, between 5 and 10 pings is suggested.
Times to Attempt Reboot
If you have an unreliable target device, limit the number of times
it will be rebooted by entering that value here. For example,
entering 5 will reboot your server up to 5 times before giving up.
Device Reboot Delay
After power cycling to reboot a device, a waiting period will occur
before the IP address is re-checked by AutoPing. This delay
allows the device time to reboot. Most devices take some time
to reboot. Windows and Linux servers can force automatic fi le
system checks which may take several minutes to complete.
To allow for startup delays, enter a time delay in the Device
Reboot Delay period. For example, a reasonable value for a
typical server might be 10 minutes (600 seconds). Entering 600
would cause the power controller to start checking the server for
normal IP operation 10 minutes after reboot.
