Maximum-Shutdown-Time negotiation

The Maximum Shutdown Time setting provides the delay needed to make

sure that a server has enough time to shut down safely when the

Management Card or PowerChute Network Shutdown client initiates a

graceful shutdown at that server.

The time reported by the Maximum Shutdown Time setting represents the

maximum delay needed by at least one of the servers listed in the

Configured Client IP Addresses list. This time is determined by a

negotiation process that is initiated when any of the following occurs:

• The Management Card turns on (a System: Coldstart event)

• The Management Card is reset (a System: Warmstart event)

• You select Force negotiation from the Maximum Shutdown Time

setting’s drop-down menu, and click Apply

During the negotiation process, which can take up to 10 minutes, each

server listed in Configured Client IP Addresses is contacted to determine

the shutdown delay needed by that server. The delay time defined by the

Maximum Shutdown Time setting will be changed, if necessary, to the

highest delay time reported by the servers.

For example:

• If 3 minutes was the result of the last negotiation process, and a new

server that requires a 4-minute shutdown delay has been added to the

Configured Client IP Addresses list, 4 minutes will be the new

Maximum Shutdown Time.

• If none of the servers needs more than a 2-minute delay, 2 minutes

will be the Maximum Shutdown Time setting.

For information about the Turn UPS Off Gracefully, Reboot

UPS Gracefully, and Put UPS To Sleep Gracefully options

that use this delay, see Control.
