2. Quickstart
The Quickstart manual gives you a short instruction into the main features and how to make
some basic settings and guides you in connecting the SNMP-adapter to the network and UPS.
Note: Before you start to configure the CS121 please ensure that your
connections are valid as described in section 1.8 Verifying the CS121
connectivity (Red network-LED off; green network-LED flashing in
intervals). Please take care that your UPS has been correctly installed
before and is running!
There are three methods available for configuring the SNMP-adapter: Telnet, terminal and
HTTP. These methods differ in the type of user interface and in the type of connection to be
used for the configuration. The telnet method shares similarities with both, the terminal and the
HTTP-method. Like the HTTP-method, the telnet method uses a network connection via the
IP-address to establish a communication, but it has the same type of user interface as used in
the terminal-method. The terminal-method requires that the SNMP-adapter be connected via
the serial cable to a host computer. The terminal and telnet methods provide the user with a
text menu indicating per alpha-numeric keys the possibilities for the user to either enter
configuration commands or navigate through the menu levels. The HTTP-method provides the
user with forms in which the system settings are either typed directly into a form or chosen per
drop down menu.
Although, all of the configuration possibilities, Telnet, Terminal and HTTP are generally
available, later in the parts of this manual only the explanation for usage of the HTTP-interface
will be provided. We strongly recommend to use the HTTP interface for configuration and
monitoring.
After you have completed the hardware setup and connected the SNMP-adapter, any of these
three methods can be used to configure the adapter for the network. For this purpose
depending on the configuration method, a communication must be established between the
adapter and user via a serial terminal session or via an established network route in a telnet or
HTTP session. CS121 allows a login only under the username “admin”. Upon entering a
telnet- or terminal-session with the adapter an authorization is required for which the default
password is:
“cs121–snmp”
2.1 Setting up 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 PC with a
cross cable to an IP address of the same network segment, e.g. 10.10.10.11 AND set the
gateway to 0.0.0.0.
2.1.1 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. 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 state 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, SieteManager, SiteMonitor, MiniSlot and Piller I/O
Board)!
