Booting the Switch

To boot the switch, perform the following:

1.

Ensure that the device console is connected to a VT100 terminal device or VT100 terminal emulator.

2.

Deactivate the AC power receptacle.

3.

Connect the device to the AC receptacle.

4.

Activate the AC power receptacle.

When the power is turned on with the local terminal already connected, the switch goes through Power On Self 

Test (POST). POST runs every time the device is initialized and checks hardware components to determine if the 

device is fully operational before completely booting. If a critical problem is detected, the program flow stops. If 

POST passes successfully, a valid executable image is loaded into RAM. POST messages are displayed on the 

terminal and indicate test success or failure.
