also be used in this instance. Check the third option for
ALL ON.
Note: If you have written a script and enabled scripting, the
script will start automatically on power up at LINE 1.
User Defined Links
You may link to other power controllers, your own web pages, or
remote web sites by entering up to four URLs and descriptions
in the Setup page. For example, enter “Site Two Power
Controller” in the description field with a URL of “192.168.0.250”
These links appear on the home page.
Access Control
The administrator can restrict user permissions to certain
outlets. To set permissions, login as admin, then create a
permissions matrix by entering user names on the left and
checking permitted outlets to the right of each user name.
Network Settings
A valid fixed IP address, network mask, and gateway must be
entered in this section.
When changing IPs, you may need to restart the unit and your
network switch to validate the new IP on an “auto-configuring”
switch port. Be sure to record the new IP address.
Use the Protect button to lock the network settings.
Once protected, the network settings cannot be
changed except by pressing the physical reset button
below the LCD.
Auto Ping Page
AutoPing Operation and Settings
AutoPing is an automatic system for rebooting IP equipment
without human intervention. To use AutoPing, first add an IP
address. Next, link that IP address to one or more outlets.
Timing settings must be considered.
Add IP Address to Auto-Ping
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 parameters control AutoPing operation:
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, a number 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 file
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.
