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. The CS121 can act as a UPS (uninterruptible power
supply) manager for all other computers in the network. 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, so in this
manual we specially reflect to the usage of such devices with your CS121. All of the basic
features and most of the product specific features and operation are explained in this manual.
This manual is the basis also for other CS121 based products like CS121, CS121BUDGET,
SENSORMANAGER, SM_T_COM, SITEMANAGER, SITEMONITOR, SITESWITCH4 und
RASMANAGER.
Note: When using the CS121 to act as a UPS (uninterruptible power supply)
manager for other computers in a network it is necessary for those
computers that are being managed by the CS121 to have its own
RCCMD installation. RCCMD is the only possibility for enabling the
communication between the CS121 acting as a UPS-Manager and other
client computers in a network. While it is possible to add the different
computers as clients in the CS121 settings it is only possible for those
computers to act as an RCCMD client when they are running RCCMD.
Each computer running RCCMD must have its own RCCMD license.
This is the only possibility for the CS121 to fulfil its function as a network
UPS (uninterruptible power supply) manager. Setting up the RCCMD
commands is described in depth in the sections 2.3.2 Quickguide to
install an RCCMD-job and 5 Additional Software.
There are several CS121 SNMP-adapters available for different UPS and although they are
mainly made for UPS, the adapters can easily be modified by simply plugging in other products
like the SITESWITCH SS4-AUX, SENSORMANAGER, and Modems in order to add new
features.
There are two basic types of CS121-adapters: external and slot cards. The basic versions for
UPS come without MODBUS-protocol, COM2 for environmental sensors and manageability
and AUX for dry-contacts alarms. For more differences please see section 1.4 Comparison.
There are other external products based on the CS121 such as the RASMANAGER, which is a
CS121 with a built-in modem. Other external devices include the SiteSwitch 4 (for the direct
control over power sockets), the SITEMONITOR 64 (for monitoring up to 64 digital alarms),
and the SITEMANAGER 2 (a device with multiple functions) which are used for handling
facility management purposes that go beyond the UPS systems.
Generally, the SNMP adapter runs an embedded Simple Network Management Protocol
(SNMP) software agent. This agent responds to the SNMP operations “gets” and “sets” and
also forwards “trap-messages” to designated recipients when critical conditions occur to the
UPS - such as low battery status. Additionally, the adapter can send RCCMD signals to client
computers running the Remote Console Command (RCCMD) initiating automatic shutdowns
or other actions in case of an extended powerfail. (The RCCMD client is an extra system
module requiring its own license.)
1.1.2 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 (CS111 and CS121SC) get inserted into the extension slots of UPS models supporting
its 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

7
functions. The MODBUS-version uses the COM2 as RS485 and is not available for
configuration. The MODBUS version can be configured only via Webbrowser, Telnet and
Default IP address.
SNMP-Traps for remote monitoring and pre-alarming: The main function of the SNMP-
adapter lays in the transmission of alarm conditions of the UPS to the monitoring station
(SNMP traps and RCCMD traps/commands). It also makes UPS data access able for users in
the network upon request. With this function it is possible to retrieve and monitor eg. battery
capacity of an UPS from an 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 Webbrowser.
Telnet: Every Adapter maybe 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 Webinterface since Telnet (and
terminalconfiguration) does only allow to setup a basic configuration of the CS121.
Works with all major NMS: The SNMP adapter 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 operated with the Cs121.
Multiserver shut down via RCCMD/RCCMD2 compatibility: The SNMP adapter CS121 is
able to initiate a network shutdown with any RCCMD modules from the UPS-Management
Software CD. A TCP/IP based RCCMD signal is sent to all RCCMD clients in the network. This
enables the remote shutdown of practically an unlimited number of client computers,
independent of which operating systems the clients are running. RCCMD is an optional part of
the UPS-Management Software. Your UPS dealer is able to provide you with Licensekeys for
the RCCMD. The UPSMAN service of the UPS-Management Software suite is an optional
module and not needed 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 only the
UPSMON (optional OEm designed Windows interface) and the Webbrowser are needed.
RS-232 UPS Protocol Router –Pipe- through: The CS121 (not BUDGET versions) is able
to transfer the UPS RS-232 protocol on COM1 directly to COM2. This allows the use of
additional monitoring software on COM2 while making extra hardware (RS-232 multiplexer) to
multiply the UPS comport unnecessary.
Logfile: CS121 has an internal logfile synchronized with either a set timeserver in your
network or from timeservers in the internet. This logfile can be accessed through the
Webbrowser, UPSMON, JAVAMON or via FTP. Due to the maximum file size of 250 lines
(depends on Hardware, newer HW131 have 2-3 more space), old entries are deleted
automatically.
Network settings: The CS121 Models are adjustable to the network environment. An auto-
sensing function 10 or 100Mbit can be activated.
Note: In large fast networks as is normally the case by CISCO or HP-Procurve
with auto-sensing switches problems can occur during the reboot of the
CS121. If this is the case and switches are being used then the auto-
sensing function might very well be the problem. Because the CS121 is
per default set to auto-sensing (ON), this can lead to the network
devices not being able to harmonise communication rates with one
another. This auto-sensing process can take a long time and is
sometimes never attainable. This taxes the CPU capacities of the
switches and can greatly slow down the network or even lead ultimately
to its failure. In this case a default network speed should be determined

8
and set after which, the CS121 can be changed from AUTO to the given
speed, "100half" for example.
Email client: The CS121 adapters incorporate a built-in SMTP email-client, which is able to
send emails automatically in the event of an alarm.
Web server: The CS121 Models contain a web-server, which displays all functions and
settings of the adapter. Non-Windows users may use the JAVAMON as graphically display for
UPS data (The JAVAMON module is not implemented in all versions.). Generally the CS121
Webserver is designed for the use with MICROSOFT INTERNET EXPLORER 6 with Active X
and is recommended as configuration and management interface.
1.2 About the communication with the CS121-Adapter
MODBUS
Modbus is the de facto standard protocol in industry which is used in the building surveillance
and facility management. All CS121 types include an MODBUS over IP interface and
MODBUS over RS232. The CS121 MODBUS types do not have an RS232 interface at COM2,
here they use an RS485 interface. The CS121 BUDGET series does not support MODBUS.
Please see the appendix where also output and protocol interface are shown.
SNMP
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. UPS systems are using in generally as Management Information Base
(MIB) 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-adapter to an 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.)
For additional information about MIB and NMS see also the section “UNMS” later on in this
manual.
For the CS121-SNMP MIB Implementation, please refer to the GENEREX download-page
http://www.generex.de/e/download/cs12x/download_p.html
This MIB is specially designed for the CS121 and includes SNMP values for all CS121 optional
products (Temperature, humidity, alarm contacts, etc.) Basicly this RFC1628CS121.MIB is the
original UPS MIB, extended by extra values supported from your CS121.
TCP
Most common way to communicate with the CS121-adapter is over TCP. CS121 includes
UPSTCP, with gives you a complete interface to integrate the adapter into your network.
1.3 The CS121 Adapter Package
The standard CS121-adapter package contains an SNMP-adapter unit with supporting
hardware and software. (Note, that the Budget-models do not have all features.)
Optional is a mounting kit for wall and DIN Rail mounting.
