10.7 TROUBLESHOOTING NETWORK SHUTDOWN
When experiencing difficulties with the Network Shutdown functionality (RCCMD), there are a few
diagnostic tools that can be used.
The first step is to ensure that the SNMP/Web adapter can reach the RCCMD Client. The actual network
connectivity between the two nodes can be checked with the usual ping command. However, the actual
RCCMD communication and related configuration can also be tested. The SNMP/Web adapter includes
a Test function that sends a test message to the Client. 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 test message, but this can be ignored
by the RCCMD Client.
The network configuration of the devices can be critical. It is highly recommended to assign static IP
addresses to the involved devices (SNMP/Web adapter and RCCMD Clients). In a DHCP environment, the
DHCP Server should be configured to always assign the same address to these devices. It is also
recommended to identify the nodes with their IP address rather than their hostname – otherwise, the
Network Shutdown may fail when the DNS server is unavailable or unreachable.
As the RCCMD Shutdown command is a TCP/IP network message, it is vital that network connectivity
devices (such as routers, switches and hubs) are protected by the UPS.
Finally, both the SNMP/Web adapter and the RCCMD Clients log their RCCMD activity. The analysis of
the logfiles may provide useful hints on the actual RCCMD communication and the eventual root cause
of the problem.
