Meridian Companion Installation and Maintenance Guide
If the number of portable telephones will stay the same and the area of
coverage will increase, it may be necessary to deregister some portables from
a CMLC, reregister them to another expanded card and replace the CMLC
with a CMBC.
If you are installing a new CMRC or CMBC, make sure enough power ports
are available on existing RPIs to accommodate new Base Stations. If there are
an insufficient number, RPIs must be added or upgraded as described in
“Installing remote power interconnect units” on page 17.
To install the new cards
1. Ensure the card slots are disabled on the Meridian 1 side. Refer to
“Using maintenance commands” on page 125.
2. Insert the card or cards from right to left as described in “Installing
Meridian Companion cards” on page 58.
The LEDs on the cards should come on immediately, flash three times,
then remain on.
3. Faceplate cabling should be installed from right to left, with the last
cable connecting the new card set to the live system. The SP LED on the
CMCC card will begin flashing.
The card LEDs should go out about 20 seconds apart.
4. If a card LED remains on, refer to the troubleshooting guidelines
described in “Troubleshooting a remote power interconnect unit” on
page 178.
5. Approximately 30 seconds after the last card LED goes out, the SP LED
stops flashing. Use the Administration Terminal to confirm the status as
described in “Card Status” on page 130.
6. Enable the new cards from the Meridian 1 system, as described in “Card
Status” on page 130.
