together (cascaded) and controlled as one system using the RS485 Connect method (see page 8). Cascading enables the
monitoring of all sensors and outlets from up to 17 IPDU-S4 or IPDU-S8 (or any combination of each model). For an RS485
Connect installation, connect a CAT5/5e/6 patch cable with RJ45 male connectors on each end (wired straight thru, pin 1 to pin 1,
pin 2 to pin 2, etc.) between the “Cascade” ports as shown in the image below. The maximum distance from the Master to the last
Slave can be no more than 1000 feet. With this properly connected and configured (pages 38 and 85) , the user can monitor the
sensors and outlets of all systems from either a single connected terminal (page 6) or through the Web Interface.
Figure 7- Cascade installation- RS485 Connection
GSM Modem Connection
(IPDU-S4 and IPDU-S8 Models only)
If alert notifications via SMS to a cell phone are desired, a GSM modem can be connected to the USB port on the IPDU-S4 / -S8
models. With a GSM modem connected, a user can receive SMS alert messages directly on their cell phone. The external GSM
modem is powered by the USB port.
A GSM modem that has been tested and is confirmed to be compatible with the IPDU-S4/ -S8 is the iCON 452. To order this
modem, contact NTI and ask for the ENVIROMUX-3GU.

OVERVIEW
Administration
The IPDU-Sx can be administered in any one of the following ways:
•Using a terminal program (e.g. HyperTerminal) via an RS232-Link, connected to Console Port.
•Using Telnet or SSH protocol via the Ethernet Port.
•Using the web interface (HTTP/HTTPS protocol) via the Ethernet Port.
The following administrative controls are available in the IPDU-Sx, thru the menu.
•View or modify the administrator & user parameters (passwords, outlet/sensor alert subscriptions, admin access, etc.)
•View or modify the network parameters (e.g. IP Address, Gateways, DNS, etc.)
•View and clear system event logs
•Clear, import, export and restore configuration parameters
•Firmware upgrades for the IPDU-Sx, thru Console port or over Ethernet
•View or modify sensor, IP device, and outlet configurations
Additional administrative controls available in IPDU-S4 and IPDU-S8 models include:
•Cascade configuration
•USB port enable/disable (for data logging)
•Three configurable IP aliases
General Functions
Manual Power Control
The user has the ability to power cycle either of the outlets by merely selecting the outlet and clicking on the appropriate action
from the web interface or text menu.
Periodic Power Control
The user can schedule power cycles for each of the outlets by setting the date and time of the reboot, the duration of the power
cycle (time ON or OFF), and whether the power cycle will be one-time, daily, weekly, or monthly. In the event that a user
schedules a monthly reboot on a date which not all months have, (e.g.. the 31st of a month), the scheduled reboot will execute on
the final day of the months with fewer days.
Associated Power Control
The user can configure an outlet to power cycle when a sensor exceeds a certain threshold or when an IP address is non-
responsive.
Sensor Alerts
A high and low threshold limit can be set for each temperature or humidity sensor. When a sensor takes a reading that is outside
a threshold, an alert notification is generated. The user can specify the frequency of alert notifications to match his or her
schedule. Also, there will be some hysteresis involved with alert notifications. This means if a sensor’s readings are moving in
and out of the threshold boundaries within a configurable period of time, additional alert notifications will not be sent. After an alert
is activated, it remains persistent even if the condition of the sensors returns back to normal, until the user acknowledges or
dismisses that alert. The user has the option to set the unit to auto-clear the alert if the sensor’s status returns to normal, and the
user can be notified if the condition goes back to normal. Alert notifications will be provided through four main methods: visible
notification via one of the user interfaces (red “Fault” LED on front panel, alert on webpage, alert in text menu), emails, syslog
message and/or SNMP traps.

11
IP Monitoring & Alerts
The individual IP addresses of the devices connected to the “AC Out” ports can be monitored. The Remote Power Controller will
ping each address, and if a response is received, the IP address status is considered to be “OK”’. The user will have the option to
configure the IPDU-Sx to cycle power at the corresponding device’s outlet if no response is received, and an alert will be logged
and sent. The user can configure the timeout for a response and the number of retries before signaling an alert and power
cycling. The IPDU-Sx can also be configured to monitor the IP addresses of the network switches and routers to which these
devices are connected, so as to determine if the problem is due to a lack of response from the device or a network failure. Alert
notifications will be provided through four main methods: visible notification via one of the user interfaces (red “Fault” LED on front
panel, alert on webpage, alert in text menu), emails, syslog messages and/or SNMP traps.
Event Log
The IPDU-Sx maintains an event log. The event log includes power-ON, system, and alert notifications, as well as user
login/logout, and user alert handling. The maximum number of log entries is 1000, and these entries are sorted in chronological
order. The log can be viewed at any time through the web interface or text menu, and can be saved as a text file. Log entries can
be removed individually or all at once. In the IPDU-S4 / -S8, the event log can be stored as a portable text file on a removable
USB flash drive.
Data Log
The IPDU-Sx maintains a data log. The data log includes readings taken from sensors, IP devices, and power outlets being
monitored. The maximum number of log entries is 1000, and these entries are sorted in chronological order. The log can be
viewed at any time through the web interface or text menu, and can be saved as a text file. Log entries can be removed
individually or all at once. In the IPDU-S4 / -S8, the data log can be stored as a portable text file on a removable USB flash drive.
Email
The IPDU-Sx can access an SMTP server to send outgoing email. Outgoing email would contain pre-formatted alert notifications.
SMTP server information can be configured using one of the interfaces. Email addresses can be configured through web pages
or text menu. Each user can have their own email address.
The email messages sent by the Remote Power Controller have a fixed format. Alert emails contain 6 fields and will have a
configurable title. The title is configurable for each sensor, device, IP address, or outlet. The title is the “email subject” in all
configuration pages. A sample message is shown below:
ENTERPRISE: Enterprise name here
LOCATION: Danner Drive
CONTACT: John Smith
DESCRIPTION: Undefined #5
TYPE: Humidity
MESSAGE: Sensor value exceeded thresholds
SNMP
The IPDU-Sx can send alerts as SNMP traps when a sensor or IP device enters/leaves alert mode, when a power outlet changes
state, and for all log events. Using SNMP network management software or a MIB browser, a user can monitor all sensor statuses
and system IP settings. The destination for SNMP traps can be configured for each user.
Note: The SNMP MIB file (ipdu-s2-v1-xx.mib for 2 port model, ipdu-s8-v1-xx.mib for 4 and 8 port models), for use with
SNMP network management software or SNMP trap receiver, can be found on the manual CD. Click on the link to open
the file; then save the file to your hard drive to use with the SNMP MIB browser or SNMP trap receiver.
GSM Modem
An external GSM modem can be connected to allow the system to send alert notifications via SMS messages. When a power
outlet changes state or a sensor crosses a threshold, an alert notification can be formatted to SMS message (see page 17) and
the modem can transmit the message to the pre-specified cellular number of each user configured to receive SMS messages
(page 45).

Security
User Settings
In order to configure and operate the IPDU-Sx, each user must login with a unique username and password. The Administrator
can configure each user’s settings as User or Administrator. An Administrator has access to all configurations and controls. A
user can monitor sensors, outlets, and IP devices. A user can edit his/her own account. Users cannot configure the unit.
IP Filtering
The IPDU-Sx allows the administrator to block access to the device from certain IP addresses. The IPDU-Sx can accept or drop
requests based on the IP filter settings. IP Filtering provides an additional mechanism for securing the IPDU-Sx. Access to the
IPDU-Sx network services (SNMP, HTTP(S), SSH, Telnet) can be controlled by allowing or disallowing connections from various
IP addresses, subnets, or networks.
Secure Connections
The Remote Power Controller supports secure connections using SSHv2 and HTTPS.
Authentications
The IPDU-Sx supports local authentication with up to 16 character usernames and passwords, and it also supports LDAPv3.
Encryption
The IPDU-Sx supports 256-bit AES encryption.

provided on the web page that appears when you insert the instruction manual CD provided into your CD ROM drive. Either click
on the link or browse the CD to locate the NTIDiscover.jar file. The Discover Tool can be run from the CD or it can be saved
to a location on your PC. Either way, to open it just double-click on the file NTIdiscover.jar . This will open the NTI Device
Discovery Tool.
Note: The Device Discovery Tool requires the Java Runtime Environment (version 6 or later) to operate. A copy of Java
version 6 is provided on the CD and a link to the web page from which it can be downloaded and installed is also on the
CD.
Note: The computer using the Device Discovery Tool and the NTI Device must be connected to the same subnet in order
for the Device Discovery Tool to work. If no devices are found, the message “No Devices Found” will be displayed.
Tip: If your Windows program asks which program to open the NTIDiscover.jar file with, select the Java program.
Figure 11- Device Discovery Tool
Click on the “Detect NTI Devices” button to start the discovery process. After a short time, the tool will display all NTI devices on
your network, along with their network settings.
How to Use the Device Discovery Tool
To Change a Device’s Settings, within the row of the device whose settings you wish to change, type in a new setting and click
on the Enter key, or the Submit button on that row. If the tool discovers more than one device, the settings for all devices can be
changed and you can click on the Submit All button to submit all changes at once.
To Refresh the list of devices, click on the Refresh button.
To Blink the LEDs of the unit, click on the Blink LED button (This feature is not supported on the IPDU-Sx.) The Blink LED
