generally delivered as a single-licence. To use a single CD ROM to shutdown multiple servers you
have to purchase additional CD license keys.
Parallel/redundant UPS systems are also manageable by the software.
The main principle is: let introduce a shutdown of a Server only when strictly necessary. A correct
Parallel Handling has therefore to manage a parallel system as a whole and always considering
redundancy. Following statements apply:
- Every alarm on any unit is immediately notified, but …
- … a reaction to a severe fault is introduced only when the minimum number of UPS –
Modules necessary to supply the load exhibits an alarming situation.
- The real Battery autonomy time of the (whole) parallel system is computed continuously.
- Maintenance on a redundant unit may be executed without annoyance to the management
system (supervisor).
In order to be managed, a UPS can be integrated into a network in two ways:
1. By means of the server which is being powered by the UPS and is integrated in the network.
In most of the cases the server is used as sub-agent and you only need the PMC-Software
without any SNMP Adapter. You need a standard serial connection between the RS232
JD11 port of the UPS and the RS232 port of the computer/server.
2. In some situations it is preferable to interface the network via an SNMP adapter. By this way
up to 50 computers can be shut down in a RCCMD environment. RCCMD (Remote Console
Command) is an additional software module, which can be triggered by the SNMP device to
executes a command (typically a shutdown command) on a remote system.
9.4.3 SNMP CARD/ADAPTER for network management / remote monitoring
The Simple Network Management Protocol (SNMP) is a worldwide-standardized communication-
protocol. It is used to monitor any device in the network via simple control language. The UPS-
Management Software also provides its data in this SNMP format with its internal software agent. The
operating system you are using must support the SNMP protocol. We offer our software with SNMP
functionality for Novell, OS/2, all Windows running on INTEL and ALPHA, DEC VMS, Apple.
Two types of SNMP interfaces with identical functionality are available: an external SNMP-Adapter
(Box) and an internal SNMP-Card. Both can manage a parallel system (N modules) and return either
global values - which are consistent for the whole parallel system - or specific values from the single
modules.
Figure 27: SNMP Adapter
The adapter may be configured via Telnet, HTTP (Web-Browser) or serial connection (Terminal). For
normal operation at least one network connection (Ethernet) is required.
The SNMP adapter can be used, utilizing the RCCMD send function, for an automatic network wide
shut down or just for informing connected users. The shut down procedure can be initiated on a low
residual battery autonomy time (downtime) or by a countdown timer which is started at the beginning
of the alarm. A shut down is therefore possible without extra input from the operator, and is fully
software controlled.
