120 MDS entraNET 900 System Guide MDS 05-4055A01, Rev. A
The following is a summary of how several screens in the entraNET
Management System can be used as diagnostic tools. For information on
how to connect to the entraNET Management System See “STEP 3—
CONFIGURE THE TRANSCEIVERS” on Page 17.
Ethernet Packet Statistics Menu
(See Figure 3-32 on Page 60 for detailed information)
This screen provides detailed information on data exchanges between
the unit being viewed and the network through the network layer. These
include:
The most significant fields are Retries, Retry Errors, Receive Errors,
and Lost Carrier Detected. If the data values are more than 10% of their
sent and received counterparts, or the Lost Carrier Detected value is
greater than a few dozen, there may be trouble with radio-frequency
interference or a radio link of marginal strength. See “Antenna Direc-
tion Optimization” on Page 122 for tips on maximizing the quality of
the received signal.
When troubleshooting throughput quality issues, a check should also be
made of the Radio Packet Statistics screen shown in Figure 3-33 on
Page 61. This menu provides a review of packet statistics from a radio
link (RF) perspective.
It is also helpful to check the RSSI of incoming signals. If the RSSI
levels in each zone are within a few decibels (dB) of each other, but less
than –90 dBm, then a check should be made of the aiming of the antenna
system. See “Antenna Direction Optimization” on Page 122 for details.
NOTE: The average signal level should be –95 dBm or stronger for
reliable performance with an allowance for fade margin.
Another place to look for trouble is in the Packets Received by Zone.
The packets should be evenly distributed across all zones (1-5% varia-
tion). If they are not, interference in the disparate zones should be sus-
