PLA450 Access and Login

I forgot the IP address for the PLA450.

The default IP address is

192.168.1.2

If you changed the IP address and have forgotten it, you might get the IP address of the

PLA450 by looking up the IP address of the default gateway for your computer. To do

this in most Windows computers, click

Start > Run

, enter

cmd

, and then enter

ipconfig

The IP address of the

Default Gateway

might be the IP address of the PLA450 (it

depends on the network), so enter this IP address in your Internet browser.

If this does not work, you have to reset the device to its factory defaults. See

Section

14.4 on page 118

I forgot the password.

The default password is

1234

If this does not work, you have to reset the device to its factory defaults. See

Section

14.4 on page 118

I cannot see or access the

screen in the web configurator.

Make sure you are using the correct IP address.

•

The default IP address is 192.168.1.2.

•

If you changed the IP address (

Section 7.2 on page 82

), use the new IP address.

•

If you changed the IP address and have forgotten it, see the troubleshooting

suggestions for

I forgot the IP address for the PLA450.

Check the hardware connections, and make sure the LEDs are behaving as expected. See

the Quick Start Guide.

Make sure your Internet browser does not block pop-up windows and has JavaScripts

and Java enabled. See

Appendix A on page 129

Make sure your computer is in the same subnet as the PLA450. (If you know that there

are routers between your computer and the PLA450, skip this step.)

•

If there is a DHCP server on your network, make sure your computer is using a

dynamic IP address. See

Section 7.2 on page 82

. Your PLA450 is a DHCP server by

default.

•

If there is no DHCP server on your network, make sure your computer’s IP address is

in the same subnet as the PLA450. See

Section 7.2 on page 82

Reset the device to its factory defaults, and try to access the PLA450 with the default IP

address. See

Section 7.2 on page 82
