Master Power On Delay
You can use Web, SNMP or console configuration commands to define how long a delay, if any, will occur
between power being applied to the MasterSwitch and master power being provided to the MasterSwitch
outlets. This allows you to sequence the master power when you want to make sure some other device has
enough time to power-up before any of the MasterSwitch load devices begin to power-up. For example:
n The MasterSwitch provides power to various servers and workstations.
n These MasterSwitch load devices connect to the network through hub components that get their
power from the same UPS as the MasterSwitch, but not from the MasterSwitch, itself.
n By delaying the MasterSwitch master power, you can ensure that the hub components are up and
running on the network before the components that connect to the MasterSwitch. The allowable delay
values are:
r Never apply power automatically (requires using a control command to turn on power)
r Apply power immediately (no delay)
r Apply power in 15 seconds
r Apply power in 30 seconds
r Apply power in 45 seconds
r Apply power in 60 seconds (1 minute)
r Apply power in 120 seconds (2 minutes)
r Apply power in 300 seconds (5 minutes)
Outlet Power On Delay
You can use Web, SNMP or console configuration commands to define how long a delay, if any, will occur
between the MasterSwitch supplying master power to an outlet (as defined by the Master Power On Delay
described above) and that outlet supplying power to the connected device. This allows you to sequence the
power from each outlet when you want to make sure the devices connected to the MasterSwitch power up in a
specific order. For example:
n The MasterSwitch provides power to various servers and workstations.
n These MasterSwitch load devices include a printer, a print server and several workstations that use the
server and printer.
n By delaying the power output of each outlet, you can ensure that the server and printer are both up and
running before the workstations that will use them. The allowable delay values are:
r Never power on automatically (requires using a control command to turn on the outlet’s power)
r Power on immediately with master (no delay)
r Power on 15 seconds after master
r Power on 30 seconds after master
r Power on 45 seconds after master
r Power on 60 seconds (1 minute) after master
r Power on 120 seconds (2 minutes) after master
r Power on 300 seconds (5 minutes) after master
