•
A wireless WAN connection to the Mobile Network Operator (MNO)
And ensure that:
•
Cables are secured to ensure reliable connections
The enterprise router performs the ISP failover by monitoring service on the WAN ports.
The ES450 is always attached to the MNO network, and when the enterprise router sends
traffic through the ES450, it passes through the MNO infrastructure to the enterprise
systems, as shown in
If the remote site equipment needs attention, the OOBM feature of the ES450 allows the
NOC or IT administrator to perform OOBM tasks on the connected equipment using the
ES450 Reverse Telnet/SSH feature. This reduces the number of on-site trips and allows
you to remotely manage connected equipment.
If the MNO offers better rates for minimal data usage, you can configure the ES450 to
reduce data transfer over the WWAN connection using the Reliable Static Route (RSR)
feature to route data sourced from the ES450 through the enterprise router primary
connection. Refer to the ALEOS Software Configuration User Guide for information on
configuring and using Reverse Telnet/SSH and RSR.
Locating the ES450 Gateway
Choosing where to place the ES450 and the antennas to get the best performance can be
a difficult task. The goal is to locate the ES450 where it can connect to the enterprise
router, have good signal coverage, and be in a low RF noise area. The options are:
•
Place the ES450, with the antennas connected directly to it, in an area with good
signal coverage that is away from the noise of other IT infrastructure equipment.
Or
•
Keep the ES450 local to the IT infrastructure, place the antennas in an area with good
signal coverage away from the noise of other electronic equipment, and cable the
antennas to the ES450.
If you are experiencing RF performance-throughput issues and you do not have the
equipment to perform an RF site survey to determine the best location, your Sierra
Wireless authorized distributor may have the tools and knowledge to help.
For simple installations in good LTE coverage, an Ethernet-connected configuration PC
running your favorite speed-test application and ACEmanager to determine network
signal strength, cell info, and signal quality will help narrow down some of the location
options.
Mounting the ES450 Gateway
Warning:
This device is not intended for use close to the human body. Antennas should be at
least 8 inches (20 cm) away from the operator.
Mount the ES450 where:
•
There is easy
access to connect to the enterprise router and to the antennas (see
).
•
The front panel LEDs are easily visible
•
There is adequate airflow
