A3 ALPHA Meter/Collector PG42-1005A
8 July 2003
If the A3 ALPHA meter/collector must be taken out of service (because of an
error condition, the telephone modem fails, etc.), the A3 ALPHA meter/collector
can be replaced with another A3 ALPHA meter/collector.
Since the REX meters within the network register with a meter/collector, a
change out procedure needs to be performed to make certain that the REX
meters will communicate with the new A3 ALPHA meter/collector. Follow these
steps to change out an old meter/collector with a new meter/collector:
1 Before beginning the change out procedure, verify that the new A3 ALPHA
meter/collector is properly configured (see Metercat Program Development
Guide for specific details).
2 Using Metercat software, perform a billing or diagnostic read on the old A3
ALPHA meter/collector. Be certain to include storage mode (either append or
replace) and all of the internal LAN controller data in the read.
3 Make a note of the old A3 ALPHA meter/collector LAN ID obtained from the
billing or diagnostic read performed in step 2.
4 Remove the old A3 ALPHA meter/collector from service. (See A3 ALPHA
Meter Technical Manual for specific details).
5 Install the new A3 ALPHA meter/collector. Be sure to follow the installation
instructions that are provided with the A3 ALPHA meter/collector to correctly
install the meter/collector.
6 Using Metercat software, perform the "Change Out LAN Collector" function.
(See Metercat user Guide for specific details). The old A3 ALPHA meter/
collector LAN ID obtained in step 3 will be needed to complete the change
out function.
After the change out command is performed, the REX meters will re-register with
the new A3 ALPHA meter/collector.
