Linux appliances feature LAN bypass

Aug 4, 2006 — by LinuxDevices Staff — from the LinuxDevices Archive

Acrosser is shipping a pair of networking appliances that support Linux 6.5 and above, and feature “LAN bypass.” The AR-M9936 is a compact, fanless “micro box” powered by a Celeron 600, while the AR-M9942 is a 1U rackmount design supporting Pentium M CPUs up to 2GHz. Both target network appliance applications.

According to Acrosser, both the AR-M9936 and AR-M9942 have a LAN bypass feature that, in the event of a system hang or power down, allows connected systems to continue to function. The bypass feature can be controlled by software, or by a watchdog timer configurable for 1-63 second operation, according to the company.

Both Acrosser systems are based on an Intel 852GM chipset, and have 128MB of onboard DDR200/266 RAM, along with an SODIMM slot for expansion up to 1.26GB. Both offer four LAN ports, each with its own Broadcom 10/100 LAN controller.

Other touted specs of both systems include:

  • 2 x USB ports
  • 2 x USB pin headers
  • 44-pin and 40-pin IDE connectors, with UDMA 33/66/100/133
  • 2.5-inch drive bay
  • mini-PCI port
  • 32-bit PCI slot
  • RS-232 port
  • RS232/422/485 pin header
  • parallel port
  • VGA port
  • eight GPIO lines
  • CompactFlash Type II slot for solid-state disk
  • PS/2 ports

The passively cooled, AR-M9942 “micro-box” measures 10.1 x 6.6 x 1.6 inches (251 x 167 x 40mm), while the 1U rack-mount AR-M9936 measures 17.6 x 8.3 x 1.7 inches (440 x 210 x 44mm).

Availability

The Acrosser networking appliances appear to be available now. Pricing was not disclosed.
