Operating
Environment
• Locate PDU in dry area.
• Rack Mount in equipment rack using mounting brackets.
• Restricted Access Location not required.
• This PDU relies on protective devices in the building installation
for short circuit and over current protection.
• Elevated Operating Ambient- If installed in a closed or multi-unit
rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore,
consideration should be given to installing the equipment in an
environment compatible with the maximum ratings of the product.
• Reduced Air Flow- Installation of the equipment should be such
 thattheamountofairowrequiredforsafeoperationofthe
equipment is not compromised.
• Mechanical Loading- Mounting of the equipment in the rack should
be such that a hazardous condition is not achieved due to uneven
mechanical loading.
• Circuit Overloading- Consideration should be given to the
connection of the equipment to the supply circuit and the effect
that overloading the circuits might have on over current protection
and supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this concern.
• Reliable earthing of equipment should be maintained. Particular
attention should be given to supply connections other than direct
connections to the branch circuit (e.g. use of power strips).
Consult the local electrical code for additional information.

The LAN module consists of integrated hardware and a network agent
softwareprogram.Thesecomponentsprovidetheabilitytocongure,
control, and monitor aspects of multiple units using a standard web
browser. The network interface can operate using Telnet and SNMP.
TheLANmoduleisconguredatthefactorytoanIPAddressof
192.168.1.110 and subnet mask of 255.255.255.0. A default gateway ad-
dress of 192.168.1.1 and a SNMP trap address of 192.168.1.200 are also
provided.
The Login dialog box requests a username and password. The factory
default username and password are “root” and “1234”, respectively. This
username has full privileges to set up, maintain, and control the unit.
LAN Module IP
Address, DHCP, and
Auto IP
Connections and Installation
The LAN module supports three IP assignment methods: Static IP ad-
dress, DHCP, and Auto-IP. If a static address is enabled, it will be used.
If a static address is not enabled, and Auto-IP is enabled, it will be used
to generate an address ONLY if DHCP is disabled, or if DHCP is enabled
and a DHCP server has not responded to the DHCP query. If both are
enabled, Auto-IP has assigned an address, and then a DHCP server
responds. The Auto-IP address will be discarded and the DHCP address
will be used.
Other Factory Defaults:
SNMP Enabled
SNMP Community Name Public
Telnet Setup Enabled
FTP Download Enabled
Web Server Disabled - Can enable with
future Firmware Update
Web Setup Disabled
ECHO Disabled
AutoIP allows the unit to obtain an address in a network that does not
have a DHCP server. AutoIP assigns a random valid address to the LAN
module in the range of 169.254.x.x to 169.254.x.x where x is between 0
and 255 and a Netmask of 255.255.0.0.

CONFIG - METERING CALIBRATIONS
The unit’s onboard voltage and current monitoring devices require a
two-step calibration procedure to achieve maximum accuracy. Each
power bank has adjustable parameters in the menu system for voltage
and current. This calibration is performed at the factory before shipment.
Operational Control of PDU
Alarm Capabilities Each power bank has four major alarm thresholds that can be adjusted.
There is an upper and lower limit for input voltage. There is also an
upper and lower limit for distributed current. An alarm is also signaled
if the current reaches two minor limits: 80% of upper limit, 90% of upper
limits.
If a major alarm threshold is surpassed the unit will respond by setting
the power bank indicator LED to red and setting the audible alarm
buzzer.
If a minor alarm threshold is surpassed the unit will toggle the LED
indicator and audible alarm. The 80% alarm toggles the LED and buzzer
once per second. The 90% alarm toggles twice per second.
If an alarm condition exists and the PDU is in monitor mode, the audible
alarm may be silenced by pressing the Alarm Acknowledge button. If the
PDU is not in monitor mode and is in the system menu, select the Alarm
Acknowledge menu item. The audible alarm will remain silenced until
another alarm threshold is exceeded.

Networking Functions
The PDU LAN Port supports the Telnet and SNMP networking functions,
which allow remote monitoring through the network environment. Table
1 lists the available Telnet commands. Table 2 lists the content of SNMP
functions – Read/Set/Trap in detail. An SNMP Manager PC Tool is need-
ed in order to implement the SNMP functions. To implement the Telnet
andSNMPfunctions,thedevicemustbeconguredproperly,suchas
assigning a valid IP address or subnet mask by using the recommended
device discovery tool.
Telnet always has the higher priority than SNMP with the timeout value of
30 seconds, which can be adjusted later.
Introduction
Telnet
Communication
You can access the PDU by typing “telnet <IP> 10001” and entering the
username and password (Default username is “root”. Default password is

Simple Network
Management
Protocol (SNMP)
An SNMP-managed network consists of three key components:
1. Managed devices
2. Agents
3. Network Management Systems (NMSs)
A managed device is a network node that contains an SNMP agent and
that resides on a managed network. Managed devices collect and store
management information and make this information available to NMSs
using SNMP. Managed devices, sometimes called network elements, can
be any type of network based device including this PDU.
The agent running in this PDU has local knowledge of measurement
information and translates that information into a form compatible with
SNMP.
An Network Manager system executes applications that monitor and con-
trol managed devices. One or more NMSs may exist on any managed
network.
The model on the following page illustrates the basic elements of an
SNMP-managed network.
