Symptom: Trouble Accessing a Port

Introduction

Use this procedure if you are having trouble accessing a PortServer TS 8/16 port. The specific problem might be that you cannot logon from a terminal or the printer or modem is not working properly.

Assumptions

This discussion assumes the following:

That the PortServer TS 8/16 itself is working, that is, that it completes the boot cycle. If it is not, see "Symptom: PortServer TS 8/16 Does Not Boot" on page 17-2.

That the network is working. This is only pertinent if all ports are not working and the malfunc- tioning ports are RealPort ports. The discussion in "Symptom: Cannot Telnet to the PortServer TS 8/16" on page 17-3goes through the steps of validating the network connection.

Running PortServer TS 8/16 Hardware Diagnostics

Use this topic to run hardware diagnostic procedures to validate the PortServer TS 8/16.

1.Connect a terminal to a PortServer TS 8/16 port.

2.If the port is still using the default configuration, configure the terminal to use the following set- tings (Otherwise, configure the terminal to match the port configuration):

VT-100 emulation

9600 baud

8-bit characters

1 stop bit

No parity

3.Reboot the PortServer TS 8/16.

4.When the LED begins blinking continuously, press the x key.

5.When the Hardware Diagnostics Menu appears, select a test to perform.
