BlueCoatSG

1)How can I check my bluecoat SG800?s pass-through card is working?
I?m very new to this device, It is a test environment, I have connected the box to our network and I?m using explicit proxy.
I have used only one adapter on the box to connect to our network, there are 2 more adapters on the device (port 0,1 & 2).
2)
When I do a telnet session, it ask for a password when I type enable, device is not accepting the admin password which I use to access the web console, what will be the other password?
