Key Statistics, described
in

Monitoring the

Network

on page 127,

should meet general
criteria listed, and/or be
similar to past values.

No change in the
interference environment
indicated.

An increase in retry rates is potentially an
indication of an interferer at the CCU. If the
number of EUMs is small, a specific EUM-link
problem could be degrading this statistic, so
further analysis may be warranted at the EUM
link level.

A

Check the CCU

Confirm power.

Power LED illuminated.

CCU has adequate
powering. Go to Test B.

Check main AC power to CCU AC-DC
adaptor. Check AC-DC adaptor power output.
Correct or replace, as required.

B

Access the CLI through
the serial port.

C

Confirm basic
configuration (

<ip>,

<ra>, <auth>

)

Configuration should be
as originally configured.

Go to Test D.

Correct the configuration and retest. If system

permission to CCU.

D

Ping CCU Ethernet port.

Successful ping
