Relay turn on for 5 seconds then off for 10
seconds
Select Ring Failure. When the Ring topology is changed, the system will short Relay Output
and light the DO LED.
Event Type:
Ping Failure
IP Address
: IP address of the target remote device. If pinging failure, the Relay will be
activated in Status “On”(closed, LED DO=Red). If pinging successful, the Relay will stay in
Status “Off” (open, LED DO=off).
Event Type:
Ping Reset Failure
IP Address:
IP address of the target device.
Reset Time (Sec):
Waiting time to short the relay output.
Hold Time (Sec):
Waiting time to the ping duration on the target device reboot sequence.
How to configure: After selecting Ping Failure event, the system will turn Relay Output to
short state and continuously ping the target device. When the ping failure occurred, the
switch will turn the Relay Output to open state for a period of Reset Time.
After the Reset Time timeout, the system will turn the Relay Output to close state. After the
Hold Time timer is timeout, the switch system will start ping the target device.
Ex: Reset Time is 5 sec, Hold Time is 50 sec.
If the ping failure occurred, the switch system will turn Relay output to open state to
emulate power switch off for 5 sec periods. After Reset Time timeout, the Switch system
will start ping target device after 50 sec periods. The period time is for target device system
booting. During the period, the switch system will not ping target device until Hold Time is
timeout.
If pinging failure, which could mean the remote device does not reboot successfully, JetNet
5020G will keep
Reset/Hold cycle
until the remote device been detected. Once pinging
successful, the Relay will be activated in Status “On”(closed, LED DO=Red).
Event Type:
Dry Output
On Period (Sec):
Type the period time to turn on Relay Output. Available range of a period
is 0-4294967295 seconds.
Off Period (Sec)
: Type the period time to turn off Relay Output. Available range of a period
is 0-4294967295 seconds.
How to configure
: Turn-on and turn-off period can assign the duration of the Relay output,
in order to set up the control signal to external device. For example, if you connect JetNet
5020G DO to DI’ of the other terminal unit, the setting can help you to change DI’ state. If
you connect JetNet 5020G DO to the power control of the other terminal units, this setting
can help you to turn on or switch off the unit.
How to turn On/Off the other device
: Type “1” into the “On period” field and “0” into “Off
Period” field and apply the setting, then it t will be triggered as a close circuit.
To turn off the relay, just type “0” into the “On period” field and “1” into “Off Period” field and
apply the setting, the relay will be triggered as a open circuit.
This function is also available in CLI, SNMP management interface. See the following
setting.
