Introduction  
Your SNMP Solo monitors one UPS attached to an EtherNet  
network using a Network Management Station. The complete  
SNMP Solo package includes hardware and software, a UPS  
cable, a power supply, a UPS Management Information Base  
(MIB), and a manual.  
SNMP Solo Features  
The SNMP Solo hardware adapter runs an embedded Simple  
Network Management Protocol (SNMP) software agent. This  
agent responds to SNMP GETS and SETS and, also, forwards  
traps to designated recipients when critical conditions occur to  
the UPS—such as going on battery backup.  
The SNMP Solo features:  
Compact Size—A small unit that takes less space on your  
work area. Dimensions are 4¾”x3½”(12 x 8½ cm).  
One Serial Port—A DIP switch changes the adapter’s  
single serial port to a configuration port for installation or to  
a communication port for normal operations.  
Remote monitoring—Monitors utility power and low  
battery status for one UPS from a remote workstation  
(NMS).  
Remote Control—Turns the UPS inverter off when the  
NMS sends the proper command.  
NMSs To Receive UPS Alarms—These traps (unsolicited  
messages) inform you about the power condition of your  
UPS.  
Works with all major NMSs on EtherNet—SNMP Solo  
works with the most widely used Network Management  
Systems: HP Open View, Novell NMS, Sun NetManager,  
IBM NetView, and many more.

Network connection ports—SNMP Solo provides a BNC  
connector for 10Base-2 connection and a UTP (RJ-45)  
connector for 10Base-T networks.  
Power connection port–SNMP Solo provides a connector for  
a 9VDC power supply.  
The following illustration shows the serial port and the DIP  
switch. The serial port serves two purposes—adapter  
configuration and UPS communication.  
Figure 3 SNMP Solo Serial Port Panel  
Status LEDs  
The LED indicators inform you of network activity, which is the  
green LNK light, and the UPS status, which is the red ERR light.  
DIP Switches  
Use the DIP switch to configure with a dumb terminal or to  
communicate with the UPS for status monitoring.

Tripp Lite  
Serial Port  
The SNMP Solo uses this port for configuration during  
installation or for communications during normal operations.  
Two 3.5” Diskettes  
Your package contains two 3.5” MIB diskettes—one in DOS  
format and one in TAR format. These diskettes contain the UPS  
MIB file. Copy the MIB file to the appropriate NMS MIB  
directory for the UPS connected to your SNMP Solo.  
The DOS disk also contains a copy of the programmed image  
file and the downloaded .exe program. See the Upload  
Firmware section for further explanation of these files.  
Configuration Cable  
Your package contains a cable labeled SM-SER-117A, female-  
to-female. Use this cable to connect the SNMP Solo serial port  
and a dumb terminal or PC for configuration. When you  
configure the SNMP Solo, be sure to set the DIP switch to the  
proper setting. Any dumb terminal or terminal emulation  
package, such as Microsoft Windows’ Terminal will work fine.  
Power Supply  
The two types of power supplies offered are:  
Power Supply Type  
Wall Cube  
Input  
120 VAC, 60 Hz  
230 VAC, 50 Hz  
Output  
9 VDC, 1 amp

WARNING:If you are using a power supply other than the one supplied  
with the SNMP Solo, be sure that the polarity of the new  
power supply is correct. If the polarity of the new power  
supply is incorrect, you may run the risk of damaging the  
adapter.

After you complete all configuration settings and connect the  
SNMP Solo to the network, check the LINK status.  
LED Status After Power Up  
At first, green and red LEDs do not light.  
Green LED begins to pulse randomly, showing  
network activity.  
Five to ten seconds after power up, the red  
LED flashes rapidly; this indicates that the  
SNMP Solo is determining which UPS model is  
connected to your system.  
After SNMP Solo determines your UPS model,  
the red LED turns off.  
The red LED pulses once whenever the SNMP  
Solo detects a communication failure.

If the SNMP Solo detects three communication  
failures in a row, the red LED turns on and  
stays on until the SNMP Solo receives a  
successful communication from the UPS.

Configuring the NMS  
To complete the SNMP Solo installation and configuration  
process, you must compile the necessary MIBs to configure the  
NMS.  
Any NMS with a MIB compiler can manage the SNMP Solo  
adapter. For instructions on how to compile MIBs for the most  
popular NMSs—Novell’s NetWare Management Station,  
Hewlett-Packard’s OpenView Network Node Manager, and  
SunConnect’s SunNet Manager; see the corresponding heading

Appendix  
This appendix has three sections: Reference, Glossary, and  
Troubleshooting.  
Reference  
This section discusses Communities, IP Addresses, Sub net  
masking, and routers/gateways.  
Communities  
A community is a string of printable ASCII characters that  
identifies a user group with the same access privileges. For  
example, a common community name is “public.”  
For security purposes, the SNMP agent validates requests  
before responding. The agent can be configured so that only  
trap managers that are members of a community can send  
requests and receive responses from a particular community.  
This prevents unauthorized managers from viewing or changing  
the configuration of a device.  
IP Addresses  
Every device on an internetwork must be assigned a unique IP  
(Internet Protocol) address. An IP address is a 32-bit value  
comprised of a network ID and a host ID. The network ID  
identifies the logical network to which a particular device  
belongs. The host ID identifies the particular device within the  
logical network. IP addresses distinguish devices on an  
internetwork from one another so that IP packets are properly  
transmitted.  
IP addresses appear in dotted decimal (rather than in binary)  
notation. Dotted decimal notation divides the 32-bit value into  
four 8-bit groups, or octets, and separates each octet with a  
period. For example, 199.217.132.1 is an IP address in dotted  
decimal notation.  
To accommodate networks of different sizes, the IP address  
has three divisions—Classes A for large, B for medium, and C  
for small. The difference among the network classes is the

IGMP multicast and other special protocols  
Subnetting and Subnet Masks  
Subnetting divides  
a
network address into subnetwork  
addresses to accommodate more than one physical network on  
a logical network.  
For example: A Class B company has 100 LANs (Local Area  
Networks) with 100 to 200 nodes on each LAN. To classify the  
nodes by its LANs on one main network, this company  
segments the network address into 100 subnetwork addresses.  
(If the Class B network address is 150.1.x.x, the address can be  
segmented further from 150.1.1.x through 150.1.100.x.)  
A subnet mask is a 32-bit value that distinguishes the network  
ID from the host ID for different subnetworks on the same  
logical network. Like IP addresses, subnet masks consist of four  
octets in dotted decimal notation. You can use subnet masks to  
route and filter the transmission of IP packets among your  
subnetworks. The value “255” is assigned to octets that belong  
to the network ID, and the value “0” is assigned to octets that  
belong to the host ID.  
For the example above, if you want all the devices on the  
subnetworks to receive each other’s IP packets, set the subnet  
mask to 255.255.0.0. If you want the devices on a single  
subnetwork only to receive IP packets from other devices on its

own subnetwork, set the subnet mask to 255.255.255.0 for the  
devices on that subnetwork.  
Subnet Mask  
Routing and Filtering  
0.0.0.0  
IP packets are transmitted to all devices.  
IP packets are only transmitted to  
devices whose IP address’s first octet  
matches the sender’s IP address’s first  
octet.  
IP packets are only transmitted to  
devices whose IP address’s first two  
octets match the sender’s IP address’s  
first two octets.  
IP packets are only transmitted to  
devices whose IP address’s first three  
octets match the sender’s IP address’s  
first three octets.  
255.0.0.0

255.255.255.0  
Gateways  
Gateway, also referred to as a router, is any computer with two  
or more network adapters connecting to different physical  
networks. Gateways allow for transmission of IP packets among  
networks on an internetwork.  
Appendix  
32  
 
Tripp Lite  
Glossary  
The Glossary section defines the terms used in the SNMP Solo  
environment.  
Agent Implemented SNMP applications in network elements  
(hosts). Agents perform the network management’s  
functions as requested by the network administrator from  
an NMS.  
Dry Closure Input Non-powered contact type inputs—switch, relay contact,  
open-collector.  
Dry Closure Output Form C dry-contact outputs which are common, normally  
open, or normally closed.  
EtherNet Local Area Network technology, originally developed by the  
Xerox Corporation, can link up to 1,024 nodes in a bus  
network. EtherNet provides raw data transfer in a rate of  
10 megabits/sec. with actual throughputs in 2 to 3  
megabits/sec. using  
a
baseband (single-channel)  
communication technique. EtherNet uses carrier sense  
multiple access collision detection (CSMA/CD) that  
prevents network failures when two devices attempt to  
access the network at the same time. LAN hardware  
manufactures use EtherNet protocol; their products may  
not be compatible.  
Gateway A computer that attaches to a number of networks and  
routes packets between them. The packets can be  
different protocols at the higher levels.  
IP Internet Protocol—The TCP/IP standard protocol defines  
the IP datagram as the unit of information passed across  
a network.  
IP Address Internet Protocol Address—A 32-bit address assigned to  
hosts participating in a TCP/IP network. The IP address  
consists of network and host portions. It is assigned to  
an interconnection of a host to a physical network.  
MAC Medium Access Control—The network layer between the  
physical and the datalink layers. Specifically, the physical  
(hardware) address exists in this layer.  
MIB Management Information Base—The database, i.e., set of  
variables maintained by a gateway running SNMP.  
NC Normally Closed —Refers to a contact switch that is  
normally closed.  
NIC Network Interface Controller—The hardware interface to  
the physical connection to the network.  
NMS Network Management Station

NO Normally Open—Refers to a contact switch that is normally  
open.  
OID Object Identifier—The variables defined in a MIB.  
Personality The current device specific software uploaded to the SNMP  
Solo.  
Router A computer that manages traffic between different network  
segments or different network topologies. It directs the  
destination IP address. The network media can be  
different, but the higher level protocols must be the  
same.  
RS-232 A specification for serial communication between data  
communication equipment and computers.  
SNMP Simple Network Management Protocol—A standard  
protocol used to monitor IP hosts, networks, and  
gateways. SNMP defines a set of simple operations that  
can be performed on the OIDs of the MIBs managed by  
the monitored Agents. It employs the UDP/IP transport  
layer to move its object between the Agents and the  
NMS.  
Sub-Agent A software module that manages specific MIB sub-groups  
for an Agent. They communicate with the Agent using a  
SMUX (multiplexer).  
TCP/IP Transmission  
Control  
Protocol/Internet  
Protocol—A  
protocol suite used by more than 15 million users with a  
UNIX association and widely used to link computers of  
different kinds.  
TES Terminal Emulation Software—Communications program to  
transform a personal computer into a terminal for the  
purpose of data communications.  
TFTP Server Trivial File Transfer Protocol Server—A host to provide  
services according to TFTP; a TCP/IP standard protocol  
for file transfer with minimal capability and overhead  
depending on UDP for its datagram delivery service.  
UDP/IP User Datagram Protocol/Internet Protocol—A TCP/IP  
standard protocol. It enables transfer of information  
between applications running on different host. It is  
referred to as an unreliable, connectionless datagram  
delivery service.

Troubleshooting  
Problem:  
The TES (Terminal Emulation Software) does not display  
anything.  
Make sure the Dip switch is set correctly. Switch 1 is ON  
Solution:  
when DOWN and Switch 2 is UP.  
This applies only when  
you power up.  
Make sure the TES’s communication parameters are  
correct.  
They should be 9600 baud rate, no parity, 8-data  
bits, and 1 stop bit.  
Make sure the ends of the SM-SER-117A cable are  
plugged into their respective ports.  
The ends of the cable indicate which belongs to the CPU and  
which belongs to the SNMP Solo.  
The end of the hooded cable nearest the label belongs to the  
CPU, and the end farthest away belongs to the SNMP Solo.  
PROBLEM: The NMS cannot ping the SNMP Solo.  
Solution:  
Make sure the network connection to the SNMP Solo is  
good.  
Solution:  
Solution:  
Make sure the cable is in good condition.  
Make sure to set the Community String [Set Access  
Controls, Type 2, Set 1 through 4]. Follow these steps:  
Name the community with any lowercase name. (A UPS  
monitors a designated community.)  
Solution  
Make sure to set the Manager Table. Set Access Controls,  
Type 3, Set 1 through 4]. Follow these steps:  
Define the Manager IP Address, Community string, and  
Access Permission together.  
The trap manager’s community should be the same number  
as the number of the community it monitors.  
The trap manager’s status is set to Accept YES to enable  
sending traps or to Accept to No to disable.
