Aperto Installation Manager Troubleshooting
This section offers solutions for problems related to the use of the Aperto Installation
Manager (AIM) utility.
Problems Connecting to the Subscriber Unit
If the Aperto Installation Manager fails to connect with the PacketWave 200 after MAC
address/frequency configuration, a “Host unreachable” message will result. Possible
causes and solutions include the following:
• Cabling problem — Verify that a crossover cable is being used, and that it is
securely connected at both ends.
• No power to the PacketWave 200 — Make sure that the Interface Box is properly
connected to an AC outlet and to the Outdoor Unit (ODU), and that the Interface
Box ODU Port’ LEDs indicate that power is on.
• Incorrect MAC address — Check the MAC address entered against the MAC address
on the PacketWave 200 ODU, and correct if necessary.
• Computer does not have fixed IP addresses — On the computer running the AIM,
ensure that the Ethernet connection is configured with a fixed IP address, subnet
mask, and gateway.
• Multiple Ethernet connections enabled — On the computer running the AIM, verify
that only the Ethernet connection to the PacketWave 200 is enabled. If multiple
Ethernet connections are enabled, the AIM will not be able to determine the correct
connection to use.
• Another application using the port — Close any application that might be using the
computer port employed by the AIM. Use the Windows task manager or LINUX/UNIX
process status as appropriate, and remove the task or reboot the computer as nec-
essary. (Sometimes Windows will have an extra Java task that is using the port.)
Problems Communicating with the Base Station Unit
After antenna alignment is finished, the Aperto Installation Manager (AIM) establishes
communication with the Base Station Unit, downloads configuration and IP information,
and performs ping and throughput tests with the Base Station Unit. The SU state during
establishment of the communication link and initialization of the SU is indicated by mes-
sages in a pop-up window. If the Aperto Installation Manager hangs at a particular state,
that state will help identify the nature of the problem.
If establishment of the communication link and initialization of the SU succeed, but the
ping and throughput tests are not successfully completed, the Aperto Installation Manager
indicates installation failure in the Results Window.
Possible causes and solutions for a failure in communication with the Base Station Unit
include the following:
