UPS Network Management Card 2 User’s Guide34
Reboot UPS (user
interface)
ups -c Reboot
(command line
interface)
Restarts the attached equipment by doing the following:
•Turns off power at the UPS after Shutdown Delay.
•Turns on power at the UPS after the UPS battery capacity returns to at least the percentage
configured for Minimum Battery Capacity or can support the load for the time
configured for Return Runtime Duration. (The parameter differs by UPS model.) The
UPS then waits the time specified as Return Delay. See “The shutdown option” on
page38.
•For a UPS with outlet groups, Power On Delay occurs after the UPS turns on and before
an outlet group turns on. On the UPS tab, configure Power On Delay for each outlet
group by using the settings option under Outlet Groups. See “The outlet groups option
(including automatic load-shedding)” on page37.
For a Synchronized Control Group action:
1. This option turns off power at the UPS models that are enabled group members after
waiting the time configured as Shutdown Delay for the initiating UPS models. See
“The shutdown option” on page38.
2. The initiating UPS waits up to the number of seconds specified as Power
Synchronized Delay to allow time for group members to regain input power. If all
group members already regained input power, this delay is omitted. If all group
members regain input power during the delay, the rest of the delay is cancelled. See the
online help for information configuring the fields used in synchronizing an SCG.
3.Return Dela y st arts when th e initiating UPS is at its configured Minimum Battery
Capacity (or Return Runtime Duration). See “The shutdown option” on page 38.
Minimum Battery Capacity (or Return Runtime Duration) of the initiating UPS is
also required of group members. However, you can reduce a group member’s
requirement by configuring that member’s Minimum Battery Capacity Offset (or
Return Runtime Duration Offset), e.g., if the initiator’s Minimum Battery Capacity
is 50%, and a member’s Minimum Battery Capacity Offset is 5%, that member needs
battery capacity of 45% to reboot. See the online help for information configuring the
fields used in synchronizing an SCG.
ups -c
GraceReboot
(command line
interface)
• T h is action is similar to Reboot UPS, but with an additional delay before the shutdown.
Attached equipment shuts down only after the UPS (or the initiating UPS, for a
Synchronized Control Group action) waits the Maximum Required Delay, which is
calculated as described in “You can also decide whether the UPS turns back on, or not,
after AC utility power is restored.” on page 39.
• F or a UPS with outlet groups, Power On Delay occurs after the UPS turns on and before
an outlet group turns on. On the UPS tab, you configure Power On Delay for each outlet
group through the settings option under Outlet Groups. See “The outlet groups option
(including automatic load-shedding)” on page37.
Put UPS To Sleep
(user interface)
ups -c Sleep
(command line
interface)
Puts the UPS into sleep mode by turning off its output power for a defined period of time:
• T h e UPS turns off output power after waiting the time configured as Shutdown Delay.
See “The shutdown option” on page38.
•When input power returns, the UPS turns on output power after two configured periods of
time: Sleep Time and Return Delay. See “The shutdown option” on page38.
•For a synchronized control group action, the NMC of the initiating UPS waits up to the
number of seconds configured as Power Synchronized Delay for enabled group members
to regain input power before it starts the Return Delay. If all group members already
regained input power, the Power Synchronized Delay is omitted. If all group members
regain input power during the delay, the rest of the delay is cancelled. See the online help
for information configuring the fields used in synchronizing an SCG.
