Network Configuration; Rccmd Shutdown; Alive Check Functionality - GE Digital Energy 1018959 Operating Manual

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.

6.1.5 Alive Check functionality

The SNMP/Web adapters support the 'UPSMAN Alive checking' functionality provided with RCCMD client
software. The RCCMD Client will periodically send network messages to the SNMP/Web adapter to make
sure the adapter is up and running, and that the network connection is OK. If the communication fails,
the RCCMD Clients will warn the user about the loss of connectivity. It is recommended to enable this
feature on the RCCMD client software (refer to the specific product documentation for details).
The 'Alive Check' network communication will target the TCP port 5769 on the SNMP/Web adapter. This
port is neither configurable nor negotiable. When using this feature make sure that traffic towards this
port is enabled in your network.
NOTE: The SNMP/Web adapter will only reply to 'Alive Check' messages if the Network Shutdown is
enabled on the adapter.
