1. INTRODUCTION
This 8-Port 48V DC Power Manager is a DC power splitter which
can distribute up to 300 milliamps of 48 volt power to up to eight
connected devices via 2-pin terminal block connections (115 watts
total across all 8 outputs). Ideal for professional applications, this unit
provides direct per-port power control via WebGUI, Telnet or RS-232.
An integrated, battery backed-up, clock allows for detailed power
scheduling based on a repeating daily/weekly schedule, or single
events. Up to 2 fans may be connected and their speed can be either
automatically controlled based on a detected temperature, or set
to a single static speed. Detailed status information about the power
input, each power output, current fan speed, and system temperature
is provided to give a comprehensive system overview.

6.5 Telnet Control
Before attempting to use Telnet control, please ensure that both the
unit and the PC/Laptop are connected to the same active networks.
To access the Command Line Interface (CLI)
In Windows 7 Click Start, type “cmd” in the search eld, and
press Enter.
In Windows XP Click Start > Run, type “cmd”, and press Enter.
In Mac OS X Click Go > Applications > Utilities > Terminal.
Once in the Command Line Interface (CLI) type “Telnet” followed by
the IP address of the unit (and the port number if it is non-standard)
and then hit “Enter”. See below for reference.
This will connect us to the unit we wish to control. Type “help” to list the
available commands.
Note: The unit’s default IP address is 192.168.1.50. If the IP address
is changed then the IP address required for Telnet access will also
change accordingly.

6.6 WebGUI Control
• Device Discovery APP
Please obtain the Device Discovery software from your authorized
dealer and save it in a directory where you can easily nd it.
Connect the unit and your PC/Laptop to the same active network
and execute the Device Discovery software. Click on “Find Devices
on Network” and a list of devices connected to the local network will
show up indicating their current IP address.
Note: The unit’s default IP address is 192.168.1.50.
By clicking on one of the listed devices you will be presented with the
network details of that particular device.
(1) IP Mode: If you choose, you can alter the static IP network settings
for the device, or switch the unit into DHCP mode to automatically
obtain proper network settings from a local DHCP server. To switch
to DHCP mode, please select DHCP from the IP mode drop-down,
then click “Save” followed by “Reboot”.
(2) WebGUI Hotkey: Once you are satised with the network settings,
you may use them to connect via Telnet or WebGUI. The network
information window provides a convenient link to launch the
WebGUI directly.

• WebGUI Overview
After connecting to the WebGUI’s address in a web browser, log into
the unit by entering the appropriate user name and password.
All primary functions of this unit are controllable via the built in
WebGUI, including Status, Device Settings, Schedule, and System
settings. The individual functions will be introduced in the following
section.
6.6.1 Status
This tab displays the current status of the various components of the
unit in real-time.
(1) Power In: Displays the voltage, current and wattage of the unit’s
main power supply.
(2) Power Out: Displays the voltage, current and wattage of each of
the 8 individual power outputs.
(3) System Temperature: Displays the unit’s temperature as measured
at 3 locations inside the case on the PCB.

9
(4) System Fan: Displays the current state of 2 external fans (optional)
including individual fan RPM, and the current fan speed thresholds,
if auto mode is enabled.
6.6.2 Device Settings
This tab provides controls for all 8 power output ports as well as control
over the optional external fans’ speed and temperature thresholds.
(1) Power Out: This section provides control over each individual
power output. The outputs may be turned on, turned off, and
renamed.
(2) Fan Setting: This section provides controls for any connected fans.
When Auto Fan Mode is enabled the fan speed will be controlled
based on the 3, user set, temperature thresholds and speed
selections. The preferred fan speed at each threshold is also user
congurable. If Auto Fan Mode is disabled, the fan speed can
be set as a static percentage of maximum power. If 2 fans are
connected to the unit, both will follow the same settings.
Note: The highest of the 3 System Temperature measurements is
used to determine which Auto Fan Mode speed (low, middle, or
high) is active when Auto Fan Mode is enabled.

10
6.6.3 Schedule
The Schedule tab provides multiple ways to automate and schedule
the powering on and off of any of the 8 power ports on this unit.
(1) Repeat Mode: Items in this section will execute at their set times on
the selected days (Sunday through Saturday) every week as long
as they are marked as “Active”.
(2) Once Mode: Items in this section are scheduled to occur a single
time on a specic date at the specied time. Each item will
automatically change to “None Active” after they have been
executed once.
Note: Each schedule item must be set as “Active” for it to activate at
the scheduled time.

11
6.6.4 System Settings
This tab provides system conguration options including changing the
network settings, downloading/restoring saved system congurations,
modifying the username and password, system time setting, and
updating the rmware.
(1) Network: This section allows for setting the unit to either Static or
DHCP mode for its IP information. When in Static mode, the IP,
Netmask, and Gateway may be set manually.
(2) Web User Setting: This section allows for the login password to be
changed. The username is “admin” and the default password is
also “admin”.
(3) System Time: This section allows user to set the system time and
date.
Note: The new setting will not take effect until “Save” is clicked.
(4) Download Current Conguration: This section allows the user to
download the current system conguration to a local PC for
restoration later.
(5) Restore Conguration: This section allows user to restore a
previously downloaded system conguration.
