Finally, it is possible to configure the actual condition that triggers the RCCMD Shutdown command:
• After X minutes that the UPS is running on battery
• At X minutes of estimated minutes remaining of battery autonomy
• When the UPS signals a low battery condition
Note that a low battery condition will force the shutdown of the configured RCCMD Clients regardless of
the chosen shutdown condition.
The configuration of the clients can be tested – the SNMP/Web adapter includes a Test function. This
allows to send either a test message to the Client, or to force a shutdown. It is important to monitor both
the messages returned from the SNMP/Web adapter and the actual result on the Client. Depending on
the configuration, the SNMP/Web adapter may successfully send the message, but this can be ignored
by the RCCMD Client.
6.1.3 Network configuration
The RCCMD Shutdown command travels across the network using standard TCP/IP protocols. Therefore,
the network configuration may affect the Shutdown process. Particularly:
• As stated above, the RCCMD Clients allow the definition of a list of trusted RCCMD Servers (that
is, RCCMD Servers allowed to send a shutdown command). When this safety feature is used, the
SNMP/Web adapter IP address must be added to the list of trusted RCCMD Servers for each
RCCMD Client. Therefore, the SNMP/Web adapter should be assigned a static IP address when
possible. If a DHCP Server is used, it should be configured so that the SNMP/Web adapter is
always assigned the same address.
• The various servers to be shutdown must be added to the list of RCCMD clients on the
SNMP/Web adapter. Although it is possible to identify the servers with their hostname, it is
strongly recommended to specify their IP addresses even if DNS hostname resolution is
configured. The network shutdown may fail if the DNS server is not available or unreachable.
• The entire network infrastructure, including routers, switches, hubs, etc. must be powered by the
UPS. Otherwise it may not be possible to reach all clients during Network Shutdown.
6.1.4 RCCMD Shutdown
When the configured condition is met, the SNMP/Web adapter will send an RCCMD Shutdown command
to the configured RCCMD Clients. This will launch the shutdown routine as configured in the Client.
In case of problems with the network communication, the SNMP/Web adapter will attempt to issue the
RCCMD Shutdown command multiple times. However, after 30s the SNMP/Web adapter will assume a
successful RCCMD Shutdown and further communication to the RCCMD Client will stop.
