Troubleshooting
Operation problems can be due to a variety of causes. The first step in resolving
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. For details, see Firmware Upgrades, page 109.
