VPN routing PC offers four PoE ports

Dec 22, 2009 — by Eric Brown — from the LinuxDevices Archive — views

Korenix announced a VPN routing computer that comes with a Linux development platform. The JetBox 9533G is based on a 667MHz Intel IXP435 RISC processor, offers four PoE and four gigabit Ethernet ports plus a WAN connection, and has three USB ports.

Designed to provide high-bandwidth network connections in industrial environments, the fanless JetBox 9533G is described as a front-end control system that also operates as a networking gateway. The latest in a number of Linux-ready, ruggedized JetBox devices — the JetBox 9300 (pictured at right) was announced in Nov. 2007 — the JetBox offers Layer 3 routing and VPN functions "for dynamic long-distance and secure network groups," says Korenix.

The JetBox 9533G is built around an Intel IXP435 Networking Processor. This 667MHz RISC processor is based on an XScale core, and includes a pair of Intel's NPEs (network processing engines). On the JetBox, it is combined with 128MB DDR2 RAM and 32MB flash, with flash expansion available via SD and CF slots.

The device's four PoE (Power-over-Ethernet) ports provide up to 15.4W power per port and 60 Watts per unit to IP cameras and other remote network devices, while also delivering control data, says Korenix. The JetBox 9533G also provides four separate gigabit Ethernet ports, as well as a 10/100Mbps WAN port. This configuration enables the JetBox to control and power four devices, while also acting as a backbone networking device that can connect to up to four gigabit switches, says the company.

Additional I/O includes three USB 2.0 Host ports, 8 DIO connections, and an RS232 console port, says Korenix. RFID, WLAN, and WiMAX modules are said to be optional.

The fanless, ruggedized, IP31-compliant chassis offers anti-vibration and anti-shock support, and can withstand temperatures ranging from -13 to 158 deg. F (-25 to 70deg. C), says Korenix.

The JetBox is said to ship with an embedded Linux Modulized Webmin UI, capable of running customized control programs. The system also ships with cross-platform applications by JavaVM, and supports the Korenix Auto-Run customization setting on SD cards, allowing customers to develop customized industrial control applications, says the company.
