Linux-based VPN router offers wide temperature range

Mar 18, 2011 — by Eric Brown — from the LinuxDevices Archive — 2 views

Korenix is readying the JetBox 9435-w, a Linux-based industrial embedded Layer 3 VPN routing computer with an Intel Xscale IXP435 667MHz RISC processor, eight 10/100 Ethernet ports, and extended temperature support. The company also has begun touting its JetBox 9400- and 9500-series as suitable platforms for network video recording (NVR) applications.

Like Korenix' other JetBox 9400- and 9500-series devices, the JetBox 9435-w is a VPN routing computer for industrial front-end control applications with requirements for high port connectivity. Like the very similar JetBox 9533G announced in Dec. 2009, the JetBox 9435-w is built around an Intel IXP435 Networking Processor. This 667MHz RISC chip is based on an XScale core, and includes a pair of Intel's NPEs (network processing engines).

The JetBox 9435-w is essentially an extended-temperature version of the JetBox 9533G, with updated networking firmware and four of its eight LAN slots reduced from 10/100/1000 Ethernet to 10/100 Ethernet. As before, there's also a separate WAN port available.

As with the earlier JetBox 9533G, the JetBox 9435-w combines the IXP435 with 128MB DDR2 RAM and 32MB flash, and offers flash expansion available via SD and CompactFlash slots. In addition to the Ethernet ports, three USB 3.0 ports are available, as is a serial console port and eight digital I/O pins.

Ruggedization features include a fanless, aluminum enclosure with IP31 protection, robust connectors, and anti-vibration and shock resistance. While all this appears to be the same as with the earlier model, the JetBox 9435-w offers a wider operating temperature range of -40 to 176 deg. F (-40 to 80 deg. C), says Korenix.

The box DIN-mountable box is slightly larger than the earlier version, measuring 6.3 x 4.4 x 4.0 inches, says the company. Running on DC 12~48V power, the device is said to consume 35 Watts.

As before, the JetBox 9435-w runs on a preinstalled, optimized Linux 2.6.20 system, and ships with a Web UI-Webmin utility. JetBox 9435-w users can develop their own customized control applications via Korenix's auto-run customization setting, stored on an SD card, said to be useful for large industrial networks.

As before, the JetBox 9435-w supports Layer3 routing functionalities, including OSPF, RIP, and IPv6, and supports VPN and DMVPN technologies. Updated networking firmware includes support for VRRP (Virtual Router Redundancy Protocol) for redundancy and Fastpath, for routing acceleration, says Korenix.

Korenix touts JetBox 9400/9500 as NVR platform

Korenix also released a press release extolling the benefits of its JetBox 9400-series and 9500-series VPN routers in a new application: network video recording (NVR).

The JetBox LAN ports can collect MJPEG format video and then use the "crontab" command for scheduling, explains Korenix. The video can be stored on SD cards that can be physically swapped onto a server.

The video data can alternatively be patch uploaded to the server using Ethernet or USB-based wireless connections, the company continues. The JetBox systems also ship with the open source Mplayer for viewing the data, says the company.


No pricing or availability information was offered for the Linux-based JetBox 9435-w. More information on Korenix' latest JetBox may be found on its JetBox 9435-w page.
