Warnings and Cautions
The Neutrik mains inlet and IEC mains outlets are not designed to be disconnected under load as they have no
breaking capacity.
Important!!: Switch o the load before removing connectors to maximise connector life.

emu3/emu3ACO Operation Guide 5
Version 2.1
General Description
General Description
The emu3/emu3ACO updates the previous IPE eMu2 PDU range.
The emu3/emu3ACO is a twelve-output power distribution unit with an embedded web server to allow IP control.
The standard model, in intelligent mode, can be set as a Master or Slave; the Automatic Changeover (ACO) model can
failover between redundant supplies.
All units contain an embedded web server, that enables continuous remote control and monitoring via the IPE
Dashboard. They can be daisychained to other emu3 units to provide up to 48 outputs via a single IP connection.
In the event of a Master unit failure, simply move the Ethernet connection to a secondary unit, which then
automatically becomes the new Master.
Units covered by this document
This document describes hardware versions v1 and v2 of the following units:
• emu3
• emu3ACO: 12-PMU Redundant power unit with automatic switchover (ACO)
Features
• Sequential Switch On: Each unit can be set up to have sequential switch on to prevent switch-on power surge.
• Power Shedding: Each output can be programmed to switch o when the unit is in a power saving mode.
• Remote Control: All outputs can be switched on or o via the IPE Dashboard web page.
• Output Monitoring: Front panel and web monitoring of status of output and fuse.
• Temperature Sensor: Rear panel connector for optional linked external temperature sensors. Critical
temperature alerts can be sent via email.
• Current Measurement: Overall current consumption can be monitored via the IPE Dashboard web page.
• Auto Changeover: In addition to all the features above the emu3ACO units have automatic changeover on
input failure, as well as a font panel switch for manual selection of input. LEDs show selected default input and
status of each input.
• Telnet protocol: Units can be accessed via Telnet; status & sensor values can be read, and switch outlets can be
programmed.

Version 2.1
Installation Instructions
Installation Instructions
This section explains how to install and connect your emu3 system.
Changing the Master emu3 IP address
By default, all emu3 units are congured with an IP address of 192.168.0.209. This address is in the space reserved
for private networks. If you are daisychaining multiple emu3 units in a Master/Slave setup, only the Master unit is
directly connected to your LAN (the Slave units are controlled from the Master’s LINK OUT port).
You will only need to change the default IP address of your Master emu3 unit in the following cases:
• There is already a machine on your network with the IP address 192.168.0.209
• Your LAN uses a dierent IP address space
If neither of the above applies, you can go straight to the next section, “Install the units and make earth connections”
on page 10.
To change the IP address space of your Master unit:
1. Congure a standalone PC (i.e. one not connected to your LAN) with the IP address 192.168.0.1.
2. Connect a CAT5e cable from the standalone PC to the LAN connector on the rear panel of your Master unit.
3. Connect an IEC mains power cable to the MAINS connector on the rear panel.
4. Plug the cable into a wall outlet and switch on.
If you are using an emu3ACO, you only need to connect one power cable, e.g. to the MAINS A connector.
5. Open a web browser on the standalone PC and enter the url 192.168.0.209
The Login web page should be displayed. If it does not, wait a few moments and refresh the web page.
6. Enter the user name and password these are both set to admin by default) and click Login. This will display the
Overview page of the IPE Dashboard.

Installation Instructions
7. Click on the gear icon to display the unit’s Conguration page.
8. Click on the down arrow to expand the Network Settings panel.
9. Enter the settings appropriate for your network’s IP address space:
–Host Name: If required, enter a text string to identify your Master unit.
–Mode: Choose from Static or DHCP.
–If you chose Static, enter an appropriate IPv4 Address, IPv4 Network Mask and IPv4 Gateway machine for
your LAN.
10. Click OK.
11. Once the unit has rebooted, remove the power and LAN cables.
12. If necessary, recongure your standalone PC to its original IP address settings.
13. Go to the next section, “Install the units and make earth connections”on page 10.

Version 2.1
Installation Instructions
Install the units and make earth connections
To install the units:
1. If required, slide the units into your 19" rack and secure with standard rack-mount bolts.
2. Make earth connections to all the units.
Make the LAN and LINK connections
The Master unit is the only unit directly connected to your LAN. Slave units do not have a direct network connection
to your LAN, but are controlled from the Master unit’s LINK OUT port.
IMPORTANT!!: Do NOT plug a network cable into a Slave unit’s LAN port if it is already connected to a Master unit.
Note: Master and Slave units can be either emu3 or emu3ACO. In the picture below, we show the Master as an
emu3ACO, connected to two emu3 Slave units.
To make the LAN connection:
1. Connect a CAT5e cable from your network hub to the LAN connector on the rear panel of your Master unit.
2. Connect a CAT5e cable from the LINK OUT connector on the rear panel of the Master unit to the LINK IN
connector on the rst Slave unit in your chain.
3. Connect any additional Slave units using CAT5e cables, going from the LINK OUT connector of the previous unit
to the IN connector of the next unit.
