i am testing SoftLayer_Account_Lockdown_Request API

i completed a test of disconnectComputeTest() method.

disconnectComputeTest finish a power and disconnect Public&Private Network link.

next,

I tested reconnectComputeTest() method. During check for a test result, i found that reconnectCompute() method's work is wrong.

Private network on - OK

Public network off - Not OK

I tested several times, but the results are the same.

why don't the Public network link connect?
