Note: When using a DC
power source (e.g., a solar
cell), Sierra Wireless
recommends placing a
fuse (1-2 Amp) on the line

to protect your power

surges due to shorts or
other line issues.

Figure 4-3: Ethernet connector
The Ethernet port of your Raven XE can be connected directly to a computer or
other Ethernet device with either a cross-over cable or a straight-through cable.
The Ethernet port on the Raven XE is auto-sensing and connects at 100baseTX.
If you are connecting the modem to a hub or switch you should use a straight
through cable or use the uplink port on the hub or switch with a cross-over cable.
Tip:
On some computers, the TCP receive window may be set to 16 kbytes. To optimize
the throughput of your Raven XE, it is recommended that you change the TCP window
from 128 kbytes to 256 kbytes using a TCP Optimizer.
