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.
Alive Check functionality
The SNMP/Web adapters support the „UPSMAN Alive checking‟ functionality provided with RCCMD client soft-
ware. 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.
RCCMD Client Relay
The maximum number of RCCMD Clients that can be managed by the SNMP/Web adapter is limited. In order to
reach a higher number of RCCMD Clients, one or more of these clients can be configured to operate as relays. Basi-
cally, the RCCMD Client needs to be configured so that it will execute a batch or script file that issues more RCCMD
Shutdown commands.
The following sample batch file lets the RCCMD Client acts as a relay station:
@ECHO OFF
SET PATH=C:\RCCMD\
# RCCMD Relay
# This batch sends RCCMD Shutdown commands to the following IP addresses
rccmd –s –a 191.168.200.5 rccmd –s –a 191.168.200.6
# … the list can be continued …
# At last, force shutdown of the local machine
ExitWin.exe shutdown force
@CLS
This procedure can also be used for a low number of RCCMD servers, as it may be easier to configure the Network
Shutdown this way rather than through the SNMP/Web adapter, especially when a number of servers need to be
shutdown simultaneously.
Clearly, the RCCMD Client acting as Relay becomes an important link in the Network Shutdown process, as it both
receives and sends RCCMD Shutdown commands. This node and related network connectivity (routers, switches
and hubs) shall therefore be protected by the UPS.
