Troubleshooting

Operation problems can be due to a variety of causes. The first step in solving
them is to make sure that all cables are securely attached and seated completely
in their sockets.
In addition, updating the product's firmware may solve problems that have
been discovered and resolved since the prior version was released. If your
product is not running the latest firmware version, we strongly recommend that
you upgrade. See The Firmware Upgrade Utility, page 35, for upgrade details.
