Product Features
Congratulations on selecting the DLI Web Power Switch, a
surge-suppressed, AC power switch with automatic reboot and
programmable power control. Features include:
Simple Web Interface
The internal web server is accessible from any standard browser.
Simply enter an IP address. The controller may be confi gured and
controlled via the web.
Auto-Ping Reboot
This automatic feature monitors a remote IP address. If a server,
router, or other peripheral goes down, the switch will automatically
reboot it, without user intervention. Up to 8 devices can be
monitored individually.
8 Switched Outlets + 2 Unswitched Outlets
Eight individually switched controlled circuits are provided with
single outlets. Outlets are spaced for large adapters and plugs.
Un-switched outlets are provided for “always on” devices.
LCD Display
A 2x16 LCD displays status for each outlet. Custom messages
can be displayed using a simple scripting language.
Password Security
Multi-user password security is provided to limit access to the
power controller. The administrator selects which outlets each
user controls.
Sequenced “On Timer”
A programmable delay timer allows outlets to be switched on in
sequence, rather than simultaneously. Most devices draw more
power when they are initially switched on. Using this timer, more
equipment can be attached to a single circuit without overloading.
Programmable scripts can also be used to create customized
power-up and power-down sequences with variable timing.
MOV Surge Suppression
A 3600J metal oxide varistor clamps power surges and spikes,
protecting all attached devices.
Scripting Language, Syslog, and Utilities
A scripting language can be used to create custom control and
reboot sequences, schedule periodic reboots, customize the LCD,
and control serial devices. Both internal and external system logs
are provided. Windows utilities send status notifi cations, warnings,
and power bills via email.
Field Upgradeable Firmware
Firmware is fi eld upgradeable via Ethernet using the web or a
command line utility.

Quick Setup
Use these shortcuts if you are an experienced installer. If this is
your fi rst time, please skim the entire manual fi rst.
1. Remove the switch from its shipping carton. Save the
carton and packing for future hardware upgrade.
2. Attach the power cord to a protected power sources with a
capacity of at least 15 amperes.
3. Attach the cable from the controller to a port on your
LAN. Switch power on. If you are connected to a switch,
you may need to cycle power to the switch to establish a
connection.
4. Ping the default address:
http://192.168.0.100 to confi rm
that a reliable network connection is established. If you
don’t receive a response, use a crossover cable and see
the Windows IP Setup section below.
5. Log in to the power controller using the default user name
admin and the password 1234
“
admin” must be entered in lower case.
6. Click on the Settings link to reach the confi guration page.
7.
Select the safest power-loss confi guration for your
installation: (all OFF, all ON, or sequential ON)
8. Confi gure the switch as described below. After each
change, click Submit and wait for the page to refresh
before continuing.
Tip: A three-bulb electrical safety-tester is handy for confi guring
the controller before attaching your equipment.

Setup
The setup page lets you select outlet names, program web link s,
startup delays, and the power loss recovery mode. You can also
change login credentials on this page.
Scripting
A scripting language using BASIC commands lets you
customize the power controller. Scripts may be started manually,
automatically on power-up, by external http commands, or by
Auto-Ping events. Find a full list of commands and example
scripts at:
www.digital-loggers.com/scripting.html
AutoPing
The AutoPing link lets you set parameters for automatically reboot
attached equipment. First specify an IP address to ping. Next
adjust the timing settings and use the checkboxes to link the IP to
specifi c circuits. For example, if a router is unreachable, you may
choose to automatically reboot both a router and a switch attached
to two different circuits. Learn more:
www.digital-loggers.com/
autoping.html
System Log
The power controller keeps a log of system events including logins
(successful and attempted), outlet switching, power interruptions,
and Auto-Ping events. Recent events are stored in the log and
accessible from the System Log page. Multiple controllers can
export logs to a single external SYSLOG server. Find information
on setting up a SYSLOG server here:
www.digital-loggers.com/
syslog.html
Logout
The controller will automatically log-out when your browser
session is closed. Click this link to log-out in advance.
Help
The Help link displays the latest online manual. Since features are
subject to change without notice, this manual may not be an exact
match for earlier controllers and earlier fi rmware versions. Find the
fi rmware revision history at
www.digital-loggers.com/revhistory.html
Windows 7, Vista
Click Start -> Control Panel. In the search box, type adapter.
Under “Network and Sharing Center”, click View Network
Connections. Right click on the adapter you’re using and click
Properties. Click the Networking tab. Select Internet Protocol
Version 4 (TCP/IPv4). Click Properties, Advanced, then under
IP addresses click Add. Enter a new compatible IP, such as
192.168.0.1, and a subnet mask of 255.255.255.0. Press Add.
Close all windows for the confi guration to take effect. Start your
Browser and type 192.168.0.100 in the URL fi eld. Log in.
Basic Operation
After power-up, the controller performs a sequence of self-tests to
ensure reliability. The static IP on the Settings page is used.
The controller may then be operated via a web browser. To access
the controller, simply enter the IP address in the URL fi eld of your
web browser. The default is
http://192.168.0.100
Home (Outlet Control) Page
To access the home page, fi rst enter the IP address in web
browser URL fi eld, then log in. User admin has access to all
features. Other users have limited access to outlets as assigned
by the administrator. When confi guring the power controller for the
fi rst time, use the default admin username and 1234 password.
The home page contains 11 links to other pages. The fi rst nine are
fi xed internal links:
Outlet Control
Clicking “Outlet Control” links to the home page used for manually
switching outlets on and off. Access to specifi c outlets is
determined by your login.

Logout
Logout ends the web session immediately. A login is required to
reconnect. Browser authentication will time-out automatically after
several minutes of inactivity.
Programmable Web Links
Four additional user-defi ned web links are provided on the outlet
control page. Factory defaults are Manual, FAQ, etc. You may
change the name and destination URL for these links on the
Settings page. These links are convenient for connecting to other
power controllers or to remote sites.
Switching Outlets On and Off
The outlet control page lets you control any pair of outlets (except
the always-on pair). A master setting also allows users (with
security access) to switch all outlets on or off.
To switch an outlet on or off, simply click to the right of the outlet
name or number. Switching is immediate.
You may also Cycle a device which is connected to the controller.
This feature is useful for rebooting Ethernet devices which may
interrupt the web link to the controller. Clicking Cycle switches
power off, waits a few seconds (as specifi ed on the setup page),
and then switches power back on. This resets the attached
device. You may also cycle all outlets using the Cycle All Outlets
button on the bottom of the page.
Depending on your web browser settings, you may need to click
the Refresh button or F5 key to update the on-screen status
display after changing settings. Screen refresh rate is adjusted on
the Setup page.
Setup Page
The Setup page allows the administrator to confi gure the power
controller. These settings are supported:
Controller and Outlet Names
Use the controller name fi elds to assign a Controller Name to the
power controller itself. Examples are “Server Rack 4 PDU” or
“Reactor Coolant Pumps”. The Controller Name fi eld appears on
the top of the home page. Assign a separate name to each outlet,
such as “Customer 4” or “Email Server” to aid identifi cation.
Power-On Sequence Delay
When a time value is entered in the “All ON Sequence Delay”
fi eld, the power controller will pause for a period of time before
switching each outlet on in sequence. This delay helps prevent the
power surges and blown circuit breakers which can occur when
multiple devices are switched on simultaneously. A delay of 60
seconds is suggested for server applications.
You may also enter a screen refresh delay in this section. If
“Enable screen refresh” is checked, and a delay value is entered,
your browser should periodically update the status screen.
Wrong Password Lockout
After three failed login attempts, the switch can disable access for
a selected period of time (0-60 Minutes).
Power Loss Recovery Modes
The power loss recovery mode setting has three settings which
take effect after a power failure:
1. You can turn all outlets off (all systems will be switched off
until manually turned on later) by checking the fi rst box.
2. You can automatically turn all outlets on using the “All ON
sequence delay” described above. Check the second
option to do this.
3. You can return to the same outlet settings that were used
prior to the power loss. The “All ON sequence delay” will

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 Defi ned 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 fi eld 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 fi xed IP address, network mask, gateway, and subnet
mask 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-confi guring”
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, fi rst 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 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.
