Install the Carrier
The 3821Plus 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 3821Plus 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.
