Attached is a brief manual for the 3060 and 4060. A single beep seems to be fan related. I cannot be absolute but is the device makes no fan noise on power up 6 it maybe over heating.<br />
<br />
btw. Fans are not field swappable the unit has to be RMA'd<br />
<br />
Hope this helps,<br />

Sonicwall 3060 Beep Codes

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.
