Use Case 4
Typical example with four computers. According to the servers' roles, you may want to shut down the
servers at different times:
• Computer hosting Dell ULNM#1 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 Dell ULNM#2 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:
• On Dell ULNM#1: Configure Shutdown Timer to None and Shutdown Duration to 120s.
• On Dell ULNM#2: Configure Shutdown Timer to 180s and Shutdown Duration to 180s.
• On Dell ULNM#3: Configure Shutdown Timer to None and Shutdown Duration to 120s.
• On Dell ULNM#4: Configure Shutdown Timer to 120s and Shutdown Duration to 120s.
The following time diagram summarizes this configuration (see Figure 27):
