Monitoring — via Network Management System
You can remote monitor the Compack -based DC power supply system from a computer connected to an Ethernet LAN which has installed a Network Management System
(NMS).
The NMS hardware and software must be previously installed in the LAN network.
Figure 13 Power system remote monitoring via NMS.
For acronym descriptions, refer to chapter “Glossary”, page 44
Requirements

Computer correctly configured, connected to
the LAN and with access to the NMS

Standard Ethernet cable (straight through
cable), to connect the controller to the LAN

Eltek Valere’s specific SNMP MIB files
(Management Information Base)
Contact your IT Department, if your computer has
difficulties while installing the MIB files or accessing the
SNMP agent (Simple Network Management Protocol).
In Short
The Compack controller implements an SNMP agent
which interfaces with the Network Management System
(NMS), enabling remote monitoring via the standard
SNMP messaging commands SET, GET and TRAP.
The SNMP agent is compatible with all major NMS on
Ethernet, such as “HP Open View”, “Sun NetManager”,
etc.
The SNMP agent responds to SNMP’s GET and SET
commands, and forwards TRAPs to designated recipients
when critical conditions occur to the DC power system,
as configured in the
Compack controller.
The GET commands provide the NMS with remote
monitoring status — e.g. Battery status, etc. — of the
power system.
The SET commands enable the NMS to remote control the power system, e.g. changing the output
voltage.
The TRAP commands are unsolicited alarm messages that the power system sends to the NMS, when
critical situations occur.
You can regard SNMP agents (network devices) that send TRAPs as “clients”, and network devices that
receive TRAPs and poll devices (issue GETs and SETs) as “servers”.
