Appendix

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 Chapter 7, Firmware Upgrade, for details.
