2 Product features
Congratulations on selecting the DLI Ethernet Power Controller, a smart rack-mount AC power switch. Its features
include:
• 8 Switched Duplex Outlets + 2 Unswitched Outlets
Eight individual switch control circuits are provided with duplex outlets. Outlets are spaced for plugs and
adapters. Unswitched outlets are provided for "always on" devices. Switched outlets are metered in two
banks. Unswitched outlets are unmetered.
• Simple Web Interface
The internal web server is accessible from any browser. Simply enter an IP. Configuration and control are
web-based.
• AutoPing™ Reboot
AutoPing continuously monitors an IP address. If a server, router, or other peripheral goes down, AutoPing
can automatically reboot it without user intervention. Several devices can be monitored simultaneously.
• Programmable LCD Display
A 2x16 LCD displays status for each outlet.
Custom messages can be displayed via user scripts.
• Multi-User Password Security
Multi-user authentication limits access to the power controller. The administrator selects which outlets each
user can control.
• Sequenced "On Timer"
A programmable delay timer allows outlets to be switched on in sequence, rather than simultaneously. Most
devices draw a surge of power when initially switched on. Using this timer, more equipment can share a single
circuit without overloads. Programmable scripts can be used to create customized power-up and shut-down
sequences with variable timing.
• MOV Surge Suppression
Dual 3600W metal oxide varistors clamp power surges and spikes, protecting attached devices.
• Scripting Language, Syslog, and Utilities
Lua scripting can be used to create custom control and reboot sequences, schedule periodic reboots, etc.
Internal and external event logs are provided.
• New Features
New features include improved power metering, a light sensor, CPU temperature sensor, longer battery life,
HTTPS, WiFi support, web power meters/charts and Lua scripting.

4 Basic setup and use
4.1 Factory defaults
The factory default network configuration is as follows:
• wired network: fixed IP address 192.168.0.100, netmask 255.255.255.0;
• wireless network: fixed IP address 192.168.254.1, netmask 255.255.255.0.
You can log in with username admin (lower case) and password 1234. It is recommended that you change the
password. You will be reminded to do so by a big red banner on the top of each page.
To reset to factory defaults, gently press the reset-to-defaults button below the LCD to enter the reset menu, then
select a reset option.
4.2 Initial setup
Use these shortcuts if you are an experienced installer. We recommend reading the entire manual for first-time
installation.
• Unpack. Save the carton.
• Attach line cords to 15A circuits.
• Attach an Ethernet cable from the controller to your LAN. Switch power on. If you are attached through a
switch, you may need to cycle switch power to establish a connection.
• Ping the default address 192.168.0.100 to confirm that a network connection is established. If you don't
receive a response, proceed to the IP setup section below.
• Log in to the power controller using the default user name admin and the password 1234. Note: "admin" must
be entered in lower case.
• Click the Settings link to reach the configuration page. Select the safest power-loss configuration for your
installation: all OFF, all sequential ON or pre-powerloss state.
• Configure the power 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 configuring the controller before attaching your equipment.
4.3 IP setup
If your network settings won't access the default IP, use a direct cable connection (temporarily bypass any switch or
router) and follow these steps to add a compatible static IP, such as 192.168.0.50.
4.3.1 Windows IP setup
Before adding an IP, close all programs and browsers. After the link is established, you can enable DHCP.

4.7 Switching outlets on and off
The outlet control page lets you control outlets. The sequence in which outlets will be switched on is determined
by settings on the Admin page. To switch an outlet on or off, simply click to the right of the outlet name or number.
Switching an outlet off is immediate. Switching an outlet on may be delayed if a different (or possibly even the
same) outlet was recently turned on. The delay acts to protect the device from simultaneous inrush currents and
limit cycling rate. 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, 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 to update the on-screen status display after changing settings. A screen
refresh setting is provided on the Setup page.
4.8 Logout
Browser logout is automatic when a session is closed or after a time-out period. You can use a menu link to log-out
in advance.

5 LCD and keypad
The LCD has 2 lines, 16 character positions each. The displayed data depends on the mode, and possibly also on
user scripting.
The keypad has 5 keys:
• (UP),
• (DOWN),
• (ON),
• (CYCLE),
• (OFF).
During normal operation, the EPCR6 LCD and keypad interface can be in one of the following modes:
• Outlet mode, which displays status of and allows to manipulate the unit's outlets;
• Meter mode, which allows to read measurements of the EPCR6 meters (bus voltages and currents, temper-
ature and illuminance) and calibrate them;
• Network mode, which displays and allows to configure network settings.
You can cycle through the modes by pressing and keys simultaneously.
If the keypad is locked via web UI, the keypad doesn't work, and if you press a key, a message about this is displayed
and stays in place until the next update of the LCD data; no action is taken.
5.1 Outlet mode
At boot, EPCR6 starts in Outlet mode.
Outlet mode
In Outlet mode, the and keys allow to choose the outlet to display. The first line shows states of all outlets.
The selected outlet is marked by a blinking cursor. Its name is displayed on the second line.
If the outlet is not locked (see below) and its physical state matches the expected state, it is displayed as:
• a plus sign for outlets that are on, or
• a minus sign for outlets that are off.
DLI EPCR6 User’s Guide: 1.7.23.0

5 LCD and keypad 11
If the outlet's physical state doesn't match the expected state, (e.g. it will be switched on in sequence , or the bus
power it is not powered but the outlet is expected to be on ), its state is marked by:
• a minus/plus sign for outlets that are physically off, but should be on, or
• a plus/minus sign for outlets that are physically on, but should be off (this should be rare).
The button switches the selected outlet on, likewise the button switches it off.
You can press and hold each of the buttons for 3 or more seconds to lock the outlet in the corresponding state.
Locked outlets can't be manipulated from web UI or with scripting, and won't be switched by using the hardware
/ keys unless you hold the corresponding key for 3 or more seconds to unlock it. Locked outlets are displayed
as:
• a zero sign for outlets that are locked off, or
• an asterisk for outlets that are locked on.
The button cycles the selected outlet unless it's locked.
Managing outlet lock state can only be done using the LCD and keypad (unless you enable SSH). Locked outlets'
states cannot be altered, and they are not affected by power loss recovery mode. However, they are still affected by
over-current, over-voltage, and low-voltage safety shutdown configuration.
5.2 Meter mode
Meter mode
In Meter mode, the and keys allow to choose the selected meter. The name of the selected meter is
displayed together with its current measured value.
Meters can be calibrated. Pressing the button starts the calibration process for the meter. The leading character
of the line, previously a whitespace , becomes an asterisk to indicate that.
Meter calibration submode
The calibration progress and method are shown on the bottom line. For example, for voltages and currents, single-
point scale calibration is used, so "1/1 SC" (first and only point, scale) is displayed.
DLI EPCR6 User’s Guide: 1.7.23.0

12 CONTENTS
You can use the and buttons to adjust the value displayed to match the reading of an external measurement
device (in his case, most likely a digital multimeter). Pressing will revert the value displayed to the original
measurement.
If this is the last point to calibrate, pressing will confirm and store the calibration values and leave calibration
mode; the display will be updated in ∼2 seconds and you will see a corrected reading. If there are more points to
calibrate, pressing saves the current value and lets you input another calibration point.
You can cancel calibration at any time by pressing .
You can reset calibration to default by pressing when not in calibration submode. You will be asked to confirm
this by pressing , or decline by pressing .
Bus voltage and current meter calibration can also be done using the web UI.
5.3 Network mode
Network mode
In Network mode, the and keys allow to select the network parameter. The selected parameter name is
displayed together with its current value.
Network configuration submode
The following parameters are present:
Parameter Type Default/sample value

Most values can be changed. Pressing the button allows to change the parameter. The leading character of the
first line, previously a whitespace , becomes an asterisk to indicate that.
Different kinds of values are changed in different ways:
• for selectable options, like static/DHCP IP address mode, WiFi mode and encryption, the / keys cycle
through the available options;
• for netmasks, the / keys decrease or increase the number of set bits in the mask;
• for IP and MAC addresses, a virtual cursor is used to allow modification of individual address bytes; the cursor
is initially placed on the last byte, and can be advanced to the preceding byte by pressing ; the /
keys increase or decrease the current byte's value;
• for the WiFi pre-shared key, any of the , or buttons generates a new key;
• the WiFi SSID can't be changed from keypad.
Options marked with a star (∗) correspond to configuration items which can have multiple values (including none)
which can be set from the web UI. You can only can only set a single value from the keypad for these, and ...
is displayed on the LCD if the option doesn't have a single value. For IP addresses, 0.0.0.0 means 'none' (e.g. no
default gateway, no syslog server, etc.).
Pressing saves the current value and starts network reconfiguration if needed. The display isn't updated in-
stantly, and you need to refresh it by pressing / . You can cancel editing at any time by pressing
.

When a time value is entered in the "All ON sequence delay" field, 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.

You can adjust the HTTP and HTTPS port bindings. If left empty, the corresponding service is not accessible. It
may be a good idea to disable HTTP if HTTPS satisfies your needs. Disabling both for security is possible; you can
use the LCD and keypad, or SSH to re-enable them if needed.
Enabling SSH will allow full control over the device, possibly bypassing most of the restrictions, e.g. setting protec-
tion. The SSH port is customizable as well. The SSH server also accepts public key authentication for a configurable
set of keys (the format is the same as in the authorized_keys file).
You can limit the severity of the locally recorded log messages by setting a minimal severity. Note that the local
log is circular, with old messages being replaced by newer ones; messages aren't persisted across reboots. For
persistent storage, you can configure the unit to send the system log to a syslog server. All messages, regardless
of severity, are sent; the receiver is expected to do the filtering.
Same subnet restriction can used to prevent remote access from outside. ONLY MACHINES IN THE SAME SUB -
NET WILL CONNECT AFTER ENABLING THIS. If connectivity is lost, use a local connection such as a laptop with
a crossover cable to restore your original network settings; you can also use the LCD and keypad for that.

The device MAC address is provided for reference only and cannot be changed in this form. If you need to change
the MAC address, you may do so via LCD+keypad, SSH or using the REST-like API. Be sure you know what you're
doing, as e.g. assigning a conflicting MAC address, or a broadcast MAC address will make an interface unusable.
To configure the unit to use static IP assignment, a fixed IP address and network mask must be entered. If a
default gateway is specified it must be on the same subnet as the IP address specified. A number of DNS server IP
addresses can be supplied separated by commas, e.g. 192.168.0.1,8.8.8.8. If DNS servers are available,
some other configuration variables can accept hostnames instead of IP addresses.
If you wish to configure the unit to use DHCP IP assignment, you needn't change the IP, network mask, default gate-
way and DNS servers; rather, after the unit obtains a DHCP lease, the parameters will be displayed for reference.
It is recommended to configure the DHCP server to provide a static lease for the EPCR6 using its MAC address
(also displayed).
When changing IP addresses, you may need to restart the unit and your network switch to validate the new IP on
an "auto-configuring" switch port.

The wireless network adapter has settings similar to those of the wired network adapter (see above), and adds
WiFi-specific ones.
It's possible to disable the wireless module entirely by unchecking the "WiFi module enabled" checkbox. The
wireless MAC address is configured to match the wired MAC address as the adapters will never be on the same
subnet in a regular setup. Use LCD+keypad, SSH access or the REST-like API if you need to change that.

the wireless network to create/connect to must be specified as the SSID.
If the unit is configured to be an Access Point and have a static IP assignment, it starts a DHCP server on the
wireless interface.
It is possible to use no encryption on the WiFi channel, or one of the WPA, WPA2 or WPA/WPA2 mixed mode with
pre-shared key (the key has to be entered then). WEP encryption is considered insecure and is not supported.
Other encryption modes are not supported.
7.5.3 Network settings protection
You may press the "protect" button to lock the network settings (this will also affect the external API settings). Once
locked, the network settings cannot be changed except by pressing the physical reset button on the front of the unit.
