Note: RCCMD clients are optional and not freeware. Most CS121 are
equipped today with a single RCCMD standard license, some UPS
makers add more licenses, other do not deliver any license at all with a
CS121. Contact your UPS maker and ask for the license regulations for
RCCMD in conjunction with your CS121.
• Certain pre-settings are imperative for all RCCMD actions.
- First of all in general regards to the CS121-adapter as an UPSMON Server, the „Enable
UpsMon Server“ and the „Use RCCMD2 Traps“ controls boxes must be checked in menu
“Network & Security Settings”. (default is ON) This enables the CS121 to execute its RCCMD
actions.
- Secondly, the CS121 adapter and the RCCMD client must both be appropriately configured
in order to reach one another using RCCMD commands over the network.
• Because the CS121 adapter plays an active roll when executing its actions “Message”,
“Shutdown” and “Command” (that is to say the CS121 -adapter sends an RCCMD-signal to an
RCCMD client), it is necessary, to enter the IP-address in parameter 1, and the port number of
the RCCMD client in parameter 2 (default port is 6003). Additionally, the RCCMD client must
either be pre-configured with absolutely no sender filter or should be pre-configured with the
IP-addresses of the particular UPSMAN servers (like UPSMAN, CS121 or other RCCMD
compatible sender) that are to function as recognized senders. These configurations take
place when installing the RCCMD client service. Further details are in the RCCMD software
documentation.
• RCCMD also includes the feature “RCCMD Trap”. RCCMD Trap is a method for sending
information to the RCCMD stations which have been applied to the CS121. RCCMD Traps
invokes messages at all RCCMD stations. Because of RCCMD plays an active roll in this
mode no receiver information is to be entered in the parameters of this job (see also following
sections). It is condition to enable the RCCMD Trap control box in the menu “Network &
Security Settings”.
• The CS121-adapter uses the parameter-based RCCMD Version 2, which can execute
different actions on the same TCP channel. RCCMD Version 1 clients can only execute one
action (shutdown file execution as default, so any RCCMD signal which is transmitted to an
RCCMD client V1 will cause a shutdown of this server ) RCCMD Version 3 is capable to
handle also redundant UPS installations (eg. PC with 2 power supplies and 2 UPS).
Note: For all 3 RCCMD event functions a list of the user configured RCCMD
receivers appear in every RCCMD event.
• The maximum number of RCCMD clients is unlimited. However it is only possible to execute
50 clients at the same time, meaning that the first 50 RCCMD clients are executed followed by
the next 50 etc. We recommend to change the timing parmeters of the RCCMD-jobs that
always less than 50 commands are transmitted at the same time. We also recommend to use
an RCCMD client as Relaystation if you want to shutdown more than 50 computers from a
single CS121. (see section 5.1.2 RCCMD client as relay station)
Note: The RCCMD timeout is 60 seconds, meaning that after this time the
communication to the RCCMD client will be stopped and a logfile entry
will be made. When an OK response from the client is received, the
system assumes a successful RCCMD Shutdown and proceeds with a
shutdown of the next 50 RCCMD clients. Every minute one batch of up
to 50 RCCMD clients can be executed.
License regulations:
Please note that in order to use these functions legally, the corresponding RCCMD client
program is installed and started from the UPS-Management Software CD. The RCCMD
license code can only be used once per installation. If more computers need to be added to
the shutdown process, additional RCCMD client licenses are required.
