○ no WLAN support

○ no native RS232

○ no out-of-band Access by monitor/keyboard to get issues solved when login via LAN

fails.

The selected x86 platforms deliver all these features, a NSLU2 couldn't provide and they

have about 3 times the computational punch of a NSLU2 at comparable power

consumption and similar form factor.

Long-term Stability: NSLU2 tends to have production tolerances from unit to unit. Many

systems run stable over long periods of time while others do fail from time to time. One of

the problem zones of NSLU2 is the USB stick interface. Some combinations of NSLU2 unit

and USB stick don't work satisfactory on the long run, while others do a perfect job without

any errors. Problems in the USB stick connection do sometimes result in damaged file

systems which includes the risk of loss of logged data. Doing regular data backups can

mitigate the risk of loosing data. Having a scenario in mind where increased reliability is

more important than the cheapest price or when aiming at installations where it is hard to

reach the unit physically to do any manual maintenance, Meteohub has been ported to Fit-

PC Slim, ALIX and ebox platforms. These platforms provide significant advantages:

● no externally plugged USB stick that had to cope as system and data hard drive, but

an internally installed, reliable SSD (Fit-PC Slim) or a slot-in mounted CF card

(ALIX, ebox) that be of industrial type specs. Both types of storage are much better

suited for non-stop operation.

● Systems are capable to reboot after a power failure, when you set BIOS parameters

accordingly.

● Ebox, ALIX and Fit-PC Slim don't loose manufacturer warranties when installing

Meteohub on it (You void Linksys warranty on the NSLU2 when you install

Meteohub firmware on the unit).

Why based on SheevaPlug?

SheevaPlug can be seen as the successor of NSLU2. It has very low power consumption,

small form factor, and prices are expected to drop significantly from the $99 it was launched

at. When using high-speed SLC SD cards (150x and better) stability of the storage media

should be fine, but only time will tell for sure.

How do I migrate from NSLU2 to x86 platform or SheevaPlug?

Migration from a running NSLU2-Meteohub to a x86 or SheevaPlug platform can be done

without help from outside and without any license costs.

1. Update NSLU2-Meteohub to version 3.0 (or newer).

2. Save Data from runnning NSLU2-Meteohub via "Application Data Backup" (page

"Maintenance"). Wait until message "full backup done" appears in "meteohub log"

(page "log files"). Copy generated file "/public/meteohub.backup" to your PC.

3. Write down the following pieces of information:

○ MAC (page "System Information")

○ System ID (page "System Information")

○ Activation Code (page "Maintenance")
