Verifying the Digi One/PortServer TS 2/4 IP Address

Use this procedure to check the IP address on the Digi One/PortServer TS 2/4.

1.Connect a terminal to a Digi One/PortServer TS 2/4 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.Press Enter to get a logon prompt from the Digi One/PortServer TS 2/4.

4.Log on to the Digi One/PortServer TS 2/4.

5.Use the set config command to verify the Digi One/PortServer TS 2/4 IP address.

Checking for Duplicate IP Addresses

Use this procedure to ensure that the Digi One/PortServer TS 2/4 and another device are not using the same IP address.

Procedure

1.From another system on the network, use the ping command to determine if the IP address is in use. The following is the command syntax:

ping ip-address

2.Do one of the following:

If there is no response to the ping, exit this procedure and return to the symptoms section of this section. Two devices using the same IP address is probably not a problem.

If there is a response, continue with this procedure.

3.Turn the Digi One/PortServer TS 2/4 off and then ping again.

4.Do one of the following:

If there is a response to the ping, there is another device using that IP address, so assign one of the devices a new IP address.

If there is no response, turn the Digi One/PortServer TS 2/4 back on. Another device is not using the IP address assigned Digi One/PortServer TS 2/4.

Pinging an IP Address

Use this procedure to deterrmine if a system can be reached from across a network.

Procedure

Attempt to ping the Digi One/PortServer TS 2/4 from another system on the network. Here is the format of the command:

ping ip-address
