1. When APC UPS expansion unit is used, please use the proper APC RS-232 cable to
connect. If "advanced port" is selected, make sure that the 940-0024C cable is connected,
and if "basic port" is selected, please connect the 940-0020B cable.
2. Advanced port provides automatic response function so that the system will detect when it
does not find any UPS. Basic port does not have this function.
The system performs scheduled detection of UPS power supply according to "Probing interval".
The system will take the following actions if there is anything abnormal with UPS:
1. AC power failed: If AC power failed, the system will delay shutdown according to the settings in
"Delayed before shutdown". If the event is cleared during this period, the system will not shut
down.
2. Low battery: If UPS battery is low, the system will shut down in five seconds. If the event is
cleared during this period, the system will not shut down.
3. Overloaded: If UPS power supply is overloaded, the system will shutdown based on the setting
of "Delayed before shutdown". If the event is cleared during this period, the system will not shut
down.
4. When the cable is connected to Advanced port, the system will shut down five seconds after
UPS timeout. If the event is cleared during this period, the system will not shut down.
Reboot this server automatically after AC power is restored
If you want the UPS to boot the NAS server automatically when AC power restores, please select
the option "Reboot this server automatically after AC power is restored".
Note: If the option is selected, when AC power fails, the NAS server will shut down based on the
setting of "Delayed before shutdown:", and then the UPS will shut down after 3 minutes. Thus if
other machines share the same UPS with the NAS server, they will also lose power when the UPS
shuts down, in this case, please properly configure the "Delayed before shutdown:" option of other
machines.
