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 airflow 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).

Installation and Operation Manual
Connections and Installation
The LAN module consists of integrated hardware and a network agent
software program. These components provide the ability to configure,
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 configured 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.

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.
LAN Module IP
Address, DHCP, and
Auto IP
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.

FAST, MEDIUM, or SLOW.
CONFIG - NUMBER OF CHANNELS
The unit can be configured to work for 1, 2, or 3 power bank devices.
Note that reducing the number of banks to 1 removes the total current
monitoring processes.
CONFIG - CONTRAST
The CONTRAST feature allows the user to adjust the contrast of the LCD
screen to a desired level.
CONFIG – SOFTWARE REV
Selecting the REV parameter will display the current revision of software
loaded into the meter.
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.
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.
Alarm Capabilities
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.

Installation and Operation Manual
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 configured properly, such as
assigning a valid IP address or subnet mask by using the recommended
device discovery tool.
Introduction
Telnet always has the higher priority than SNMP with the timeout value of
30 seconds, which can be adjusted later.
You can access the PDU by typing “telnet <IP> 10001” and entering the
username and password (Default username is “root”. Default password is
“1234”). The telnet session has a 30 second timeout.

Installation and Operation Manual
Networking Functions
An SNMP-managed network consists of three key components:
Simple Network
Management
Protocol (SNMP)
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.

Installation and Operation Manual

Interactions between the NMS and managed devices can be any of four
different types of commands: reads, writes, traversal operations, and
traps.
• Reads - To monitor managed devices, NMSs read variables main-
tained by the devices.
• Writes - To control managed devices, NMSs write variables stored
within the managed devices.
• Traversal operations - NMSs use these operations to determine
which variables a managed device supports and to sequentially
gather information from variable tables (such as IP routing tables) in
managed devices.
• Traps - Managed devices use traps to asynchronously report certain
events to NMSs.
Accessing the SNMP interface requires a tool, such as a network man-
agement station. The management station relies on an agent at a device
to retrieve or update the information at the device, including device con-
figuration, status, and statistical information. This information is viewed
as a logical database, called a Management Information Base (MIB). MIB
modules describe MIB variables for a variety of device types and com-
puter hardware and software components.

Key SNMP Settings
SNMP read community name
SNMP read/write name
“public”
“public”
You can access the SNMP settings using Telnet <unit IP address> 9999.
The default username and password is “root” and “1234”, respectively.
Option 0 thru 3 on the Setup page:
Option 0 - Up to three SNMP trap addresses may be entered.
Option 1 - Read Community Name [default = “public”]
Option 2 - Read-Write Community Name [default = “public”]
Option 3 - SNMP Trap Destination Address
SNMP Security

Authorization: Changing public and private community
names is recommended to prevent unauthorized access to
the device.
You can disable SNMP set commands to make use of
SNMP read-only.
SNMP MAX and MIN
Data
MAX and MIN data fields are calculated by the PDU.
To reset a MAX field, write a “0” (zero) to the data location.
To reset a MIN field, write “999” to the data location.
The data location will then refresh with new calculated values.

This section addresses the loading and compiling of MIBS into Network
Management Systems (NMS). Alternatively, you can consult the docu-
mentation of other NMS on MIB loading and compilation. Below are the
instructions for HP OpenView and IBM NetView, but you should still con-
sult HP or IBM documentation, as the products may change.
General MIB Usage
From the GUI of HP OpenView or IBM NetView
Follow these steps to load the PDU MIBt:
Copy the files into the directory /usr/OV/snmp_mibs of the network man-
agement station.
This is the default directory where HP OpenView and IBM NetView look
for MIB documents. If you place them elsewhere, specify the explicit path
names in the loadmib graphical interface.
Set the permissions so that you have read access to the MIBs.
From the GUI menu, choose Options > Load/Unload MIBs.
Follow the instructions in the platform documentation, to compile or load
the PDU MIB.
From the Command Line Interface of HP OpenView or IBM NetView
Issue the /opt/OV/bin/xnmloadmib -load filename command, to load the
MIB file.
There is no need to compile MIBs for use with Vista Infrastructure Moni-
toring (VIM) [formerly Enterprise Device Manager]. However, there are a
few steps to take before VIM can communicate with a device, and these
are mostly the same for every device.
MIB Use With Vista
Infrastructure
Monitoring
1.
2.
The device must be configured with network settings including an
IP address, subnet mask, and default gateway.
The device must be configured to allow the VIM software to be an
SNMP manager. This usually involves entering the IP address of
the VIM server into the device’s NMS list or device access list.
3.
The device must be configured to send traps to the VIM server.
This involves entering the IP address of the VIM server into a
table along with the SNMP community string.
