Install the Carrier

The 3821

Plus

card resides in a COMSPHERE 3000 Series Carrier. The carrier must be

installed in a rack before the modem cards can be installed in the carrier.

card requires a Shared Diagnostic Control Panel (SDCP) for control and

configuration of individual modems. It also requires a Shared Diagnostic Unit (SDU) if

the modems will be under control of an NMS, or if the SDCP is used for more than one

carrier. Instructions for the installation of the SDCP and SDU, as well as the 3000

Series Carrier and its power supply, can be found in the
