Network Management Card

• In reboot and sleep actions:

– Immediately before the initiating UPS begins waiting the time specified as Return

Delay, by default it waits up to 120 seconds (its configurable Power Synchronized

Delay) for any UPS that does not have input power to regain that power. Any UPS

that fails to regain input power during that delay does not participate in the

synchronized restart, but waits until its own input power returns before restarting.

– The LEDs on the front of the UPS do not sequence their lights as they do for a

normal (not synchronized) reboot or sleep action.

• UPS status and events are reported in the same way for synchronized actions as for

actions on individual UPSs.

Actions (for a single UPS and Synchronized Control Groups)

Use the actions described in the following table for individual UPSs and for

Synchronized Control Groups, within these guidelines:

• All actions except Put UPS in Bypass and Take UPS Off Bypass are supported:

– For Synchronized Control Groups of Symmetra UPS or Smart-UPS models

– For all individual APC UPSs except Silcon UPS and AIS 5000 UPS models

• Put UPS in Bypass and Take UPS Off Bypass are supported:

– Only for individual UPSs, not for Synchronized Control Groups

– Only for Matrix-UPS, Symmetra UPS, and some Smart-UPS models

To control a Silcon UPS or an AIS 5000 UPS, see Control options for

Silcon UPS and AIS 5000 UPS.

For more information about the delays and settings in the following table, see

Configuration Options and The Sync Control Option. To apply Test UPS

Alarm to a Synchronized Control Group, see Diagnostics.

When you select Yes for Signal PowerChute Server Shutdown in the Web

interface, initiating a Turn UPS Off, Reboot UPS, or Put UPS To Sleep

action is equivalent to selecting Turn UPS Off Gracefully, Reboot UPS

Gracefully, or Put UPS To Sleep Gracefully in the control console
