LAN Link LED
This green LAN Link LED next to the Ethernet 10BASE-T connector should
light when the Ethernet connection is made.
If this green LED is off,
•
Make sure the network cable is firmly connected to the hub or switch.
•
Does the hub or switch work correctly in the network. Check the
power supply of the hub/switch.
•
Use a CAT5 straight-through cable to connect to a normal hub.
Check the cable for any physical damage.
•
If connecting the
VIP
directly to a PC without a hub use a crossover
cable
Transmit LED
The orange LED next to the Ethernet 10BASE-T connector should flash
shortly whenever the
VIP
transmits a packet, e.g. when accessing the unit
with a Web Browser or with
VIP -SW1
. If the TX LED fails to come on, perform
the following checks:
•
Are all units connected correctly with the power supply? Check
power supplies and connections.
•
Did you configure the correct IP address for your
VIP
?
•
Is your Web Browser configuration correct?
•
Is the TCP/IP protocol installed on your PC operating system and is an
IP address assigned to the PC?
•
Are Subnetmask and Gateway setup properly?
If you have problems with the installation of your network, please contact
your network administrator.
Terminal program
In case the terminal program fails to connect to the
VIP
Terminal Port,
check:
•
Is the right COM-port interface of the PC selected for the terminal
program and are the settings correct. Is the cable connected to the
terminal and not the data port of the
VIP
. The default settings of
19.200 kb/s, 8 data bits, no parity, 1 stop bit (8N1) should be pro-
grammed for the terminal program.
•
If the data exchange between the terminal program and the
VIP
still
does not work, check the serial cable. Does
VIP
answer when you
enter a question mark ’
?
’.
•
Disable the local echo if you see duplicate characters on your
screen.
Troubleshooting a TCP/IP Network Using a Ping Utility
To find out if a
VIP
is reachable in your network, try to ping your unit by typ-
ing the following command in a DOS box.
