PowerChute Network Shutdown configuration parameters

Note: By default, the PowerChute clients initiate a graceful shutdown when the UPS has 120

seconds of runtime remaining. If the servers need additional time to shut down safely,

configure the Low battery alarm threshold setting at the user interface display of the

Symmetra PX 250 or Symmetra PX 500 UPS. From the UPS System screen on the user

interface display, select User Configuration, then Alarm Settings. The valid range for the

Low battery alarm threshold is 0 (no shutdown will occur) to 3600 seconds (1 hour).

For MGE Galaxy models, you must use the UPS Tuner to set the shutdown time.

Parameter Description

Maximum Required

Delay

Displays the delay required to ensure that each PowerChute client has enough time

to shut down safely when the UPS or the PowerChute client initiates a graceful

shutdown.

When Force Negotiation is selected, the Network Management Card polls each

server listed as a PowerChute Network Shutdown client for information on the time

it needs for a graceful shutdown. This delay is recalculated whenever the

management interface of the UPS turns on or is reset. (This option is not available

for the Galaxy 300 or Galaxy 7000 UPS devices.)

Maximum Required Delay

is the longest shutdown delay needed by any server on

the list, plus two additional minutes to allow for unforeseen circumstances. The

negotiation can take up to 10 minutes.

If you do not select Force Negotiation, two minutes is used by default as the

shutdown delay for all clients.

On-Battery Shutdown

Behavior

After the PowerChute Network Shutdown clients shut down their computer

systems, this parameter determines whether the UPS turns on automatically or must

be turned on manually when input power is restored.

Note: This option is not available on the MGE Galaxy 300 or MGE Galaxy 7000

UPS.

Authentication Phrase The case-sensitive phrase of 15 to 32 ASCII characters to be used during MD5

authentication for PowerChute communication. The default Administrator setting is

admin user phrase.
