Table 38

Troubleshooting the Web Configurator

PROBLEM

CORRECTIVE ACTION

I cannot access the

web configurator.

If the Prestige’s Ethernet IP address or management IP address has changed,

then enter the new one as the URL.

Your computer’s IP address must be on the same subnet as the Prestige’s

Ethernet IP address or management IP address (whichever you use to access the

Prestige).

See

Section 12.9 on page 99

to check that pop-up windows, JavaScripts and

Java permissions are allowed.

Ping the Prestige. In the computer, click

Start

, (

All) Programs

Accessories

and

then

Command Prompt

. In the

Command Prompt

window, type "ping" followed

by the Prestige’s IP address (192.168.5.1 is the default management IP address)

and then press [ENTER]. The Prestige should reply. Otherwise, make sure your

computer’s Ethernet adapter is installed and functioning properly.

You may also need to clear your Internet browser’s cache.

In Internet Explorer, click

Tools

and then

Internet Options

to open the

Internet

Option

s screen.

In the

General

tab, click

Delete Files

. In the pop-up window, select the

Delete all

offline content

check box and click

. Click

in the

Internet Options

screen

to close it.

If you disconnect your computer from one device and connect it to another device

that has the same IP address, your computer’s ARP (Address Resolution

Protocol) table may contain an entry that maps the management IP address to the

previous device’s MAC address).

In Windows, use

arp -d

at the command prompt to delete all entries in your

computer’s ARP table.

I access the wrong

Prestige when

using the

management IP

address for access.

This problem may occur if you have more than one Prestige on the same LAN.

Disconnect your Prestige from the network and connect directly through the

Prestige’s

port. You may also need to delete your computer’s ARP table entry

for the Prestige’s IP address (see above).

Table 39

Troubleshooting the Password

PROBLEM

CORRECTIVE ACTION

I cannot access the

Prestige.

The username is admin. The default password is 1234. The

Password

and

Username

fields are case-sensitive. Make sure that you enter the correct

password and username using the proper casing.

If you have changed the password and have now forgotten it, you will need to

restore the default configuration file (see

Section 2.3 on page 31

). This restores

all of the factory defaults including the password.
