• IndividualDelayTimer (range: from 0 - 3600 seconds; data type: integer). Each outlet also has its own
individual delay variable (IndividualDelayTimer) that is accessible through either a serial (HyperTerminal) or
Ethernet (Telnet and SNMP) interface. If IndividualDelayTimer is not set (equal to 0), the individual outlet
delay function is not enabled.
If both the GlobalDelayTimer and IndividualDelayTimer parameters are not set, the power-on sequence
function is off automatically.
When a PDU is powered on for the first time, all the relays are off, and the power-on sequencing is not used.
You must turn on the relays by using the web interface or SNMP. You must also set the values for the
GlobalDelayTimer and IndividualDelayTimer, if they are used. After that, when the PDU is turned on (or power
is restored), the outlet power-on sequence and behavior are controlled by the following settings:
• Previous state of the outlets (on or off)
• GlobalDelayTimer value
• IndividualDelayTimer value
The outlets that were off before the PDU was turned off (or lost power) will stay off after power is restored.
The outlets that were on before the PDU was turned off (or lost power) will be tuned back on in a sequence
that is determined by the timers. If the timer values are zero, the only delay is the PDU boot-up time, which is
10 seconds. If there are values in the delay timers, the turn on time is the sum of following three values:
• PDU boot-up time (10 seconds)
• GlobalDelayTimer value
• IndividualDelayTimer value
The following example shows what you can expect to see if power to the PDU is restored after a power
outage.
• PDU boot-up time = 10 seconds
• GlobalDelayTimer = 5 seconds
• The previous outlet state for the PDU is:
Outlet 1 On
Outlet 2 On
Outlet 3 On
Outlet 4 Off
Outlet 5 On
Outlet 6 On
Outlet 7 On
Outlet 8 On
Outlet 9 On
Outlet 10 Off
Outlet 11 On
Outlet 12 Off
• The IndividualDelayTimer for each outlet has the following settings:
Outlet 1 1 Sec
Outlet 2 2 Sec
Outlet 3 3 Sec
Outlet 4 5 Sec
Outlet 5 2 Sec
Outlet 6 2 Sec
Outlet 7 4 Sec
Outlet 8 1 Sec
Outlet 9 2 Sec
