While Setting Up Your Configuration

Introduction	This section describes the ways you can use to isolate problems that you may
	encounter while setting up a PathBuilder S21x switch to pass IP traffic over PPP
	links. For discussion purposes, the following network configuration (shown in
	Figure C-1) is assumed.
		Note
		The configuration of the local PathBuilder S21x switch and the number to call
		can be obtained by defaulting the node—selecting “Default Node” from the
		CTP’s Main menu.

Step

Action

1Ensure that the STS LED is ON to confirm that power is connected and that the unit is working. (Other LEDs may be ON or blink occasionally.)

2If the STS LED flashes continuously for more than 30 seconds after the power is applied, the software image in the flash is corrupted and the node is waiting for software to be coldloaded. Refer to the Software Installation and Coldloading Manual for more infromation on cold- loading software.

3If you are connected to the control port using an async terminal, (9600 bps, 8 bits, no parity), type “AT <CR>” and confirm that the Path- Builder S200 series switch outputs “OK.” Then log into the CTP.
