It is not connect with power supply 208 by power supply switching unit K2 and power supply switching unit K3.
Carry out port blocked state verification when, be closed power supply switching unit K1~K3 first.Subsequent first utilizes the
One network diagnosis unit 207 executes the instruction of the ports X3 in ping Ethernet interfaces 201, finally detect whether can ping it is logical,
And it checks in address resolution protocol (Address Resolution Protocol, referred to as ARP) table of equipment under test 204 and is
It is no that there are the MAC Address of network diagnostic device 207.
If the first network diagnosis unit 207 can not ping lead to the ports X3 of equipment under test, while the ARP table of equipment under test
In be not present first network diagnosis unit 207 MAC Address.So according to the relevant regulations of EC61375-2-5 standards, then it represents that
The ports X1 of equipment under test are in blocked state at this time.
Network diagnosis unit 207 is connect with the ports X2 of the first Ethernet interface 201 then, and tests and passes through pingX4
Whether the ports port test X2 are in blocked state, and principle is identical as X1 port test principles, and details are not described herein.
Because when testing the port block state of equipment under test, need to test each port of equipment under test,
So next needing to test the ports X3 of equipment under test 204 and the ports X4.
When the ports X3 and the ports X4 to equipment under test 204 are tested, by equipment under test 204 and third Ethernet interface
203 connection, and use principle identical with the test ports X1 tests the obstruction shape of the ports equipment under test X3 and the ports X4 respectively
State.
If four ports of equipment under test 204 meet the relevant regulations of EC61375-2-5 standards, then it represents that tested to set
Standby 204 match with the corresponding contents in preset standard, and equipment under test 204 has passed through port blocked state verification.
In addition, when equipment under test 204 is connect with the first Ethernet interface 201, can also carry out the selected test of top node,
Intermediate node loses test, test is added in intermediate node, test is added in original intermediate node and just run time test.
