Typical example with four computers. According to the servers' roles, you may want to shut down the
servers at different times:
•
Computer hosting

is directly attached to the UPS (USB/Serial). The Shutdown
Controller must be installed on the server that will be the last one to shut down.
NOTE: On Pulsar series, this computer must be powered by the master outlet.
•
Computer hosting

requires a long delay to shutdown, such as hosting database or
VMware.
•
Computer hosting
Dell ULNM
#3
must be the last one to be shutdown because other servers depend
on it, such as File server.
•
Computer hosting
Dell ULNM
#4
is another server that must be stopped before computer 2 or 3
(Web server), or this computer can also be stopped for load shedding purposes (workstation).
The recommended configurations are:
