configuration of the SNMP adapter please ensure that the DIP switches are in the correct
position. Please also refer to the section 1.5 CS121 overview in this manual.
1.7.2 ... via LAN
Connect the CS121 with RJ45 cable (not included) to your LAN.
1.8 Verifying the CS121 connectivity
After the CS121-adapter is connected to the UPS and to the Computer 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. (Models with
Hardware Version131 do also indicate uncompressing the firmware files with flashing red LED
lightening) The boot process can take up to 3 minutes. If there is an error, the red LED does
not go out. For more detailed information about the UPS-Status LEDs, please see section 1.5
CS121 overview.
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.
• Ping the SNMP-Adapter
Perform a PING-command from the SNMP-station or from another computer in your network
resp. NMS (Network Management Station).
If you do not get a response, check the SNMP-adapter network connection and IP-address of
the SNMP adapter. 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 adapter does not answer every ping signal at the same
speed, due to different sized UPS protocols. If UPS protocols are of
extensive size a timeout can occur briefly. A permanent timeout however
is an error.
