1. The CS121 Family - Introduction
1.1 About your CS121
1.1.1 General Information
The CS121-series are a group of products designed especially for critical resource
management within technical facilities. All of these products share many of the same basic
CS121 features, and some have special components and functions.
The CS121 products are most commonly used for the management of UPS systems, get UPS
data via SNMP and display all available data and failures. These information will be forwarded
to desired clients. In addition a shutdown of these clients could be executed via our RCCMD
Multi-Server Shutdown Software.
This user manual describes the main function of the CS121 and the function of additional
components.
The construction and the configuration of the CS121 devices are universal. The adaption has
to be fit in different UPS devices from worldwide located manufacturers. This user manual
cannot show all alternatives. Different screenshots and described details have to be
interpreted correspondingly.

1.4 Functional Overview of the CS121
The CS121 is working with an integrated Simple Network Management Protocol (SNMP)
software agent. This agent exchanges data with the UPS via “get” and “set” commands and
forwards Trap Messages to desired receivers. This Trap Messages inform the user about
critical situations of the UPS, e. g. a power failure. In addition the CS121 can trigger RCCMD
(Remote Console Command) signals, messages, and shutdowns.
RCCMD is an additional single licensed software.
Otherwise the control of the UPS is possible, e. g. switching on bypass.

Functional Overview of the CS121_R_II
1.4.1 Functionalities of your CS121
SNMP Adapter CS121/CS121 Slot: The SNMP adapter is a compact unit requiring minimal
workspace (ca. 28x69x126 mm for the external adapter CS121L). The slot card versions of the
adapter get inserted into the extension slots of UPS models supporting such a card type.
Serial Port: Two DIP-switches change the adapter's serial port (COM2) to a configuration
port for installation or to a communication port for environmental sensors, modem or other
functions. The MODBUS-version uses the COM2 as RS485 interface and is not available for
configuration. The MODBUS version can be configured via web-browser only, Telnet and
default IP address.
SNMP-Traps for remote monitoring and pre-alarming: The main function of the SNMP-
adapter is the transmission of alarm conditions of the UPS to the monitoring station (SNMP
traps and RCCMD traps/commands). It also makes UPS data for users in the network upon
request available. With this function, it is possible to retrieve and monitor e. g. battery capacity
of an UPS from a SNMP management station. The event settings configuration menu also
allows for SNMP trap testing.
Remote Control: With this function it is possible to switch the UPS to Bypass (depending on
the model) or start battery tests. This remote command is executed either via the Network
Management Station or the UPS Management Software or any web-browser.
Telnet: Every Adapter can be reconfigured via the network, using Telnet or HTTP after the
initial configuration of an IP address for the adapter. Current UPS data can also be shown
using Telnet. Generally we recommend to use the web-interface, since Telnet (and terminal
configuration) allows to setup a basic configuration of the CS121 only.
Works with all major NMS: The CS121 works with most, widely used Network
Management Systems, e. g. HP Open View HP UNIX and Microsoft Windows NT, Novell NMS,
Spectrum, Sun NetManager, IBM Net View/600 and others. All SNMP systems, which either
allow the compilation of the MIB or already incorporate MIB RFC 1628 for UPS Systems, can
be used with the CS121.
Multiserver shutdown via RCCMD/RCCMD2 compatibility: The CS121 is able to initiate a
network shutdown with any RCCMD modules from the UPS-Management Software CD. A
TCP/IP based RCCMD signal will be send to all RCCMD clients in the network. This enables

11
the remote shutdown of practically an unlimited number of client computers, independent of
the operating systems of the clients. RCCMD is an optional part of the UPS-Management
Software. Your UPS dealer is able to provide you with license keys for the RCCMD Software.
The UPSMAN service of the UPS-Management Software Suite is an optional module and not
required for that basic CS121 operations. We recommend to use the UPSMAN service only, if
the UPS is connected via serial or USB cable, if a CS121 is connected, you just need a web-
browser for the monitoring.
RS232 UPS Protocol Router –Pipe- through: The CS121 (not BUDGET versions) is able
to transfer the UPS RS232 protocol on COM1 directly to COM2. This allows the use of
additional monitoring software on COM2, while making extra hardware (RS232 Multiplexer) to
multiply the UPS comport unnecessary.
Log File: The CS121 got an internal log file synchronized with either a timeserver in your
network or from Internet timeservers. This log file can be accessed by web-browser,
UPSMON, JAVAMON or via FTP. The size of the log file is 250 lines, older entries will be
overwritten automatically.
Network Settings: The CS121 models are adjustable to the network environment. An auto-
sensing function, 10Mbit or 100Mbit can be selected.
Email Client: The CS121 adapters incorporate a built-in SMTP email client, which is able to
send emails automatically, if an error occurs.
Web-Server: The CS121 models possess a web-server, which displays all functions and
settings of the adapter. Non-Windows users may use the UPSView as graphically display for
UPS data.
Network Connection: The below figure displays a CS121 into a network environment. The
CS121 is communicating with the UPS and displays all available data.
Figure 1: CS121 into a Network Environment
1.5 The Communication with the CS121-Adapter
MODBUS
Modbus is the de facto standard protocol in industry, which is used in the facility management.
All CS121 types include an MODBUS over IP interface and MODBUS over RS232. The CS121
MODBUS device types possess a RS485 interface at COM2.
SNMP

12
The SNMP (Simple Network Management Protocol) is the Internet standard protocol for
managing devices on IP networks and is defined and standardized in Requests for Comments
(RFCs) specifications. Generally UPS systems are using the Management Information Base
(MIB) with the RFC1628 specification, which defines UPS specific devices.
The CS121 also comes with the standard MIB RFC1628. Because of this MIB is already part
of most SNMP software products, it is not required to compile the MIB (please search the MIB2
directory tree for a “UPS-MIB”). If you want to include your CS121 to a SNMP-Management
station, which does not have the standard MIB RFC1628, you can download the specific MIB
from our website http://www.generex.de/e/download/cs12x/download_p.html. Copy the MIB file
to the appropriate MIB-directory of your SNMP-station and compile this file. In most cases your
SNMP already has implemented this MIB and a compilation is only necessary, if you want to
read extra information than just UPS (e.g. for SENSORMANAGER, etc.).
UPSTCP
The most common way to communicate with the CS121 is over TCP. The CS121 contains
UPSTCP, which gives you a complete interface to integrate the adapter into your network. All
others use TCP for the access via web-interface (UPSView, UNMS II) or SNMP or MODBUS.
1.6 CS121 Overview of the Connections and LEDs
For CS121 L, LM, SC, SCM and other slot cards:
Figure 2: Connections of the CS121

Note: Into configuration mode the full functionality of the CS121 is not
available! Please change to a valid network address and put DIP-switch
1 to position ON as soon as you made your basic network settings! After
this, please continue configuring your CS121 in your network. Please
follow up the procedure in chapter Error! Reference source not found.
Error! Reference source not found. in this manual.
Please note, that the CS121 Budget versions got no COM2 port!
6) Serial interface (COM1): For the connection to the UPS
Note: UPS interface cable (external devices only): Please use the manufacturer’s
serial port cable that came with your UPS to connect the UPS with the SNMP-
adapter. Please contact your UPS manufacturer, if you have questions. Only use
the original RS232 UPS cable for communication, which was provided with the
UPS. If your UPS has a contact closure port, please use the manufacturer’s special
cable. Please consult your UPS dealer for further information regarding special
cables.
7) Power supply, the external CS121 got an external power supply (9 –12VDC)
Note: If you are using a different power supply unit from the one in the adapter
package, please consider that the polarity is set correctly. The adapter
might be damaged if the wrong polarity is used. The power supply
voltage should be at least 9V, 12 V is recommended.
For the CS121SC models C and the slot card, there are no power supply
units. These units will receive power directly from the UPS device. The
SNMP adapter C and slot card both incorporate a variable 9-36V input.
2. Quickstart
This quickstart describes the basic functions and settings of the CS121. The CS121 can be
configured via Telnet, Terminal and HTTP. The Telnet configuration uses the same network
interface as the HTTP configuration. The Terminal configuration requires a serial connection to
a workstation.
We recommend the configuration via HTTP, because it is the most comfortable one and that is
why we describe the HTTP configuration in this user manual.
After you finished the CS121 hardware setup, all 3 configuration modes are at present. If you
want to use the Telnet or HTTP configuration, it is required to add a temporary network route
to the CS121 configuration mode IP address 10.10.10.10.
Please use the following access data:
User: admin
Password: cs121-snmp
3. Initial Operation of the CS121
3.1 Connect your CS121 ...
In generally you can select between 3 ways to configure the CS121:
You can execute the HTTP configuration via web-browser.
You can execute the Terminal configuration via web-browser.

15
You can execute a Terminal configuration via the serial interface (CS121 device types with a
COM2 port only) with the CS121 configuration cable (optional, not included). This
configuration-mode allows you to make the basic settings for the network connectivity and for
the configuration of the event and alarm settings.
3.1.1 ... via LAN
Connect the CS121 with RJ45 cable (not included) to your LAN.
3.1.2 ... via serial port
The CS121 contains two serial ports (not BL and BSC-versions), COM1 provides the connection to the
UPS and COM2 is used for the configuration of the SNMP adapter.
Configuration cable (not included):
With the configuration cable you could connect the serial port (COM2) of the CS121 and the serial port
of a workstation with terminal software. It is sufficient to use a Dumb-Terminal or Terminal emulation
program, such as e. g. Microsoft-HyperTerminal. Please ensure during the configuration of the CS121,
that the DIP switches are into position OFF.
CS121 MINI/CS121 R_II:
It is required, that the DIP Switch 2 remains in position OFF, otherwise the device will not start (valid
for CS121Minislot/CS121R_II built 2008- 2010 from serial number 0123M-0001 to 0123M-1135).
3.2 Verifying the CS121 Connectivity
After the CS121 is connected to the UPS and to the workstation via serial port or via LAN, please verify
the connectivity before you start to configure the CS121. The setup system can be checked before and
after a configuration using the following 3 steps:
UPS Status Displays (LEDs)
During the boot procedure, the red LED is on, whereas the green LED is off, please take a look into
chapter 1.6 for the complete signaling.
After five to ten seconds after the boot-process, the green LED flashes rapidly; this indicates that the
SNMP-adapter is trying to start the communication. The adapter will indicate its communication
accessibility with random green LED flashes.
Network status LEDs
The LEDs, integrated into the LAN-Connector (RJ45-), will signal a connection to the network with
green and with yellow network connectivity.
CS121 Ping Echo
Perform a PING command from the SNMP station or from another workstation in your network.
If you do not get a response, check the CS121 network connection and IP address. The IP address of
the adapter is set to 10.10.10.10, if DIP Switch 1 is in position OFF (configuration mode).
Note: The different response rates during the ping process do not correspond
to an error. The CS121 does not answer every ping signal at the same
time, due to different sized UPS protocols. If UPS protocols are of
extensive size a temporary timeout can occur. A permanent timeout
however is an error.

16
3.3 Setup of the Basic Network Configuration
Note: We recommend the following settings for the operation of the CS121 via
cross cable (Ethernet cable for the connection directly). Set the IP address of the workstation
with a cross cable to an IP address of the same network segment, e.g. 10.10.10.11 AND set
the gateway to 10.10.10.10.
A network cross cable is a PC-PC network cable, which does not require a switch or a hub
between 2 network workstations (2). Most modern workstation network cards have an auto
detection, so any network cable may be used. Only if you do not have such a cable, connect a
switch or Hub between your workstation and the CS121 (1).

3.3.1 DHCP –Obtain an IP address automatically
By default DHCP is off at all CS121. From CS121 FirmWare Version 4.25.x you can switch on
DHCP via DIP switch 2 manually. Therefore the CS121 will get a DHCP IP address from the
DHCP server during reboot. Prior of that, you should detect the MAC address of the CS121 to
be able to find the IP address on your DHCP server. You can also use the GENEREX
Netfinder tool (http://www.generex.de/generex/download/software/install/NetFinder.zip). This
tool searches all CS121/BACS devices into your network environment. We recommend to use
static IP addresses, because the CS121 is used for multi server shutdowns via RCCMD too
and it might be, that the DHCP server got a breakdown. For that reason the delivery default of
the CS121 is always with DHCP OFF!
Note: The function DHCP ON/OFF is valid for the following models only: all
CS121 HW 131 and all BACS II Webmanager Budget (not valid for all
CS121 HW 121, SiteManager, SiteMonitor, MiniSlot, CS121_RII and
Piller I/O Board)!
3.3.2 Establishment of a static CS121 IP address manually (default delivery state)
The minimum requirement to operate the SNMP-adapter is to set the IP address, subnet mask
and the UPS model:
The DIP-switches of the SNMP-adapter firstly need to be set for the configuration. DIP-
switch 1 is switched OFF in the top position as well as DIP switch 2 is switched OFF.
Note: For slot versions you have to insert and remove the device for any
reboot-process. This will not have any effect on your UPS but we
recommend doing such operations only when the UPS is not supplying
any load!

As soon as the network-LED is flashing, add a TCP/IP route on your computer for IP-
address 10.10.10.10. This is done via a call from your command line e.g. "route add
10.10.10.10 <your computers IP address>“. See also route -? for more help of route syntax.
Test if you can ping the device now: Enter command „ping 10.10.10.10“ and check if there is
any response. Now you can connect with any Telnet or HTTP-software and continue with the
configuration.
3.3.3 Using HTTP/Webbrowser
Attention! Please finish all configuration menus via “Apply”button. After you
finished your whole confguration, please note, that it is reqzuired to execute the “Save, Exit &
Reboot” function via CS121 menu “Save Configuration”.
The entire configuration can be done via Webbrowser. Please use the default IP-address
10.10.10.10 and the TELNET password (default: “cs121-snmp”). The username is always
“admin”.
Please do never close the web-browser or telnet window during saving process! If you close
the configuration window too early, you might destroy the configuration file “upsman.cfg”.
Please note, that the reboot process could last up to 3 minutes.
For the configuration using the webbrowser please observe the following:
We recommend the use of Microsoft Internet Explorer 6.x (or higher) or Mozilla 1.3x. Please
note, that Java scripting has to be activated. Using Internet Explorer, the corresponding
settings have to be made under “Internet options” - “security”.
We also recommend never to use the history function of the browser, as this may lead to
multiple transfer of commands (e.g. delete event jobs) to the adapter.
Upon entering a HTTP-configuration session, the user is required to enter a username,
”admin”, in addition to the password ”cs121-snmp”.
Figure 5: HTTP - Administrator login
Note: If the HTTP-method does not seem to be available, check to see
whether or not the red LED UPS Status glows.
Call Configuration, “UPS Model & System” and choose your UPS Model from the drop
down list. Further configurations like Power, baud rate, cable type etc. were made
automatically (ensure your Browser has enabled JavaScript) and do not need to be set. We
strongly recommend to keep the default settings for this UPS unless you have instructions
from the UPS maker.

Change to menu “Save Configuration” and click “Save Configuration”.
3.3.4 Configuration using Telnet / MS-HyperTerminal
Use of Telnet, enter the command: „telnet <IP-Address>“, whereas <IP-Address> is in the
configuration mode set to 10.10.10.10. Please note, that since CS121 firmware version 4.x, the
basic settings (IP address, network settings) are at present only.
