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.
The 3821 Plus 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 COMSPHERE 3000 Series
Carrier Installation Manual , Document Number 3000-A2-GA31.
