Specific embodiment
The invention will be further described for explanation and specific embodiment with reference to the accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of PoE interchanger band of low cost carries the ageing testing method of PD, including following step
It is rapid:
1. test prepares
(1) prepare PoE separator (model PS-1218TG), the equipment working principle: from poe switch port after by electricity,
Data are separated with electric power again.The equipment can dial-up selection output voltage 5V, 12V and 18V after electric power separation.
(2) prepare cement resistor and measure and calculate the resistance that PoE separator need to load according to the test environment of Fig. 1
Value, to make poe switch port output can reach maximum output, such as data in following table.Cement is bought by obtained resistance value
Resistance.
(1) cement resistor in 27 Europe and 6 Europe is fixed in iron machine box, picks out electric source line interface, then access PoE separation
Device completes the design of load.
2. researching and developing burn-in test step
Following test method is suitable for while supporting the PoE interchanger of at and af standard.
(1) number of access PoE separator is calculated.Generally there is early warning value (to exceed by the PoE output power of software control
The value is it is not recommended that be further added by PD) and peak power output, power supply, which designs, also part surplus, so maximum belt carries test and is at least up to
To the peak power output of interchanger.
If PoE separator connects 6 Europe resistance, single port exports about 30W, and PoE separator number=interchanger PoE exports early warning
Value/30 be rounded, then plus 1, for avoid beyond power supply design output valve, an increased PoE separator can choose connects 27 Europe electricity
Hinder 15.4W.
If PoE separator connects the resistance in 27 Europe, single port exports about 15.4W, and PoE separator number=interchanger PoE is defeated
Early warning value/15.4 are rounded out, then plus 1.
Such as: it is 120W, maximum output value 130W that certain PoE interchanger, which exports early warning value, and a kind of scheme can access
PoE separator is 5, wherein 6 Europe resistance 4,1 of 27 Europe resistance.Another scheme connects 27 Europe resistance separators 8.
(2) the PoE separator for accessing 27 Europe resistance is selected into output voltage 18V；Access the PoE separator choosing of 6 Europe resistance
Select output voltage 12V.
(3) PoE interchanger to be measured is put into climatic chamber, then terminates poe switch port with 100 meters of cables, one,
The other end accesses the port P+D/IN of PoE separator, and instrument of giving out a contract for a project is accessed with short cable again in the port D/OUT.As Fig. 2 gives out a contract for a project test
Topo graph.
(4) the test environment of climatic chamber, instrument of giving out a contract for a project of reruning are adjusted, burn-in test checks instrument of giving out a contract for a project in the time
The packet loss of port statistics and the indicator light of separator.
(5) determine that whether data transmission is exported with electric power normal, indicates that power supply is normal if the indicator light is always on if separator,
Indicate that data transmission is normal if packet loss is in critical field.
Factory's burn-in test step
(1) more PoE interchangers while aging hardware components select whole ends including the PoE function of all of the port
The scheme of the exportable power of mouth, PoE separator connect 27 Europe resistance, and every port exports 15.4W, are fully loaded with up to whole maximum work output
Rate.
(2) PoE interchanger is put into climatic chamber, adjustment test environment, PoE interchanger all of the port are used as required
Cable connects the port separator P+D/IN, then the port PoE separator D/OUT is connected two-by-two, causes all ends of PoE interchanger
Choma road is connect after the equipment that can give out a contract for a project introduces data packet with one of port and takes back loop again, carries out aging.As Fig. 3 is surveyed from ring
Try topo graph.
(3) determine whether work is normal in the PoE exchange hardware device aging time.Pass through observation PoE separator instruction
Lamp determines whether the power supply of the port PoE is normal；Indicate that data transmission is normal if the flashing of poe switch port indicator light.It is offline
It takes a sample test, extracts fraction PoE interchanger and access instrument test of giving out a contract for a project.
According to the above method, tester only need to be maximum according to the single port peak power output and complete machine of PoE interchanger
The quantity of resistance value and access PoE separator that output power goes selection to access, builds the environment of burn-in test, simply and can be big
The verifying of batch.
A kind of PoE interchanger band of low cost provided by the invention carries the ageing testing method of PD, compared with prior art, tool
It has the advantage that
1 need to switch cement resistor and PoE separator voltage output value achieves that PoE interchanger af and at standard testing
Switching, test method simple and flexible.
Factory's missing high power PD band carries equipment to 2 phases than before, and the PD load design is at low cost, can carry out batch and more may be used
Formula is surveyed in the aging leaned on.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
Specific implementation of the invention is only limited to these instructions.For those of ordinary skill in the art to which the present invention belongs, exist
Under the premise of not departing from present inventive concept, a number of simple deductions or replacements can also be made, all shall be regarded as belonging to of the invention
Protection scope.
