Configuring Share-UPScontinued

Until Low

Until Low Battery shutdown mode is similar to the standard

Battery

operation of the UPS. During a utility failure, Share-UPS

shutdown mode

allows the UPS to run on battery until utility power is

 

restored, or until the battery is exhausted. If Share-UPS

 

detects a UPS Low Battery condition, it sends a Low Bat-

 

tery signal on all ports for a period of time equal to the Low

 

Battery Signal Time and then shuts down the UPS.

 

If utility power returns after the Low Battery timer has

 

begun, Share-UPS will continue the countdown and force

 

the UPS to cycle power.

 

This mode is useful for applications which require maxi-

 

mum run time from the UPS.

 

 

Timer shutdown

In Timer shutdown mode, Share-UPS allows the UPS to

mode

operate on battery for a user-specified length of time before

 

shutting down the UPS. See “DIP switches: Table 5” on

 

page 23 for the available timer settings.

 

If power returns before the timer has run out, Share-UPS

 

returns to On Line status. When the timer runs out or when

 

Share-UPS detects a Low Battery condition in the UPS,

 

Share-UPS sends a Low Battery signal for a period of time

 

equal to the Low battery signal time and then shuts down

 

the UPS.

 

Note: If you are using PowerChute software, set the shut-

 

down delay for a time longer than Share-UPS timer

 

setting. Otherwise, if the power returns after the

 

server shuts down, the server may not restart. To set

 

the shutdown delay, go to ConfigurationEvent

 

Actions and select UPS On Battery from the Event

 

list and Shut Down Server in the Action box. Click

 

Options and enter a setting for Begin Shutdown

 

Sequence in __ Seconds. Click OK.
