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. The Digi Port
Authority-Remote utility is helpful in the troubleshooting process for
determining the port signal status. SeeConfiguring the Ethernet Interface
with Digi Port Authority-Remote.
Assumptions
This discussion assumes the following:
• That the PortServer TS 8/16 itself is working, that is, that it com-
pletes the boot cycle. If it is not, see "Symptom: PortServer TS 8/16
Does Not Boot" on page 75.
• That the network is working. This is only pertinent if all ports are not
working and the malfunctioning ports are RealPort ports. The dis-
cussion in "Symptom: Cannot Telnet to the PortServer TS 8/16" on
page 75 goes through the steps of validating the network connec-
tion.
