WCS-2 and WCS-4 Subrack Overview
RF Donor (RFD) Card and RF Donor (RFD) HB Card
The RFD Card (PN 7633229-xx) or RFD HB Card (PN 7841277-00) are the interfaces for RF signals between
the CAN or WIN and the RF source, such as the BTS, eNodeB, BDA, or e-POI. (See table for Table 1 on page 5
for RFD Card and RFD HB Card deployment information.) You can only install RFD Cards and RFD HB Cards
in a Subrack that is configured as a Classic CAN or WIN as follows:
• WCS-2: Slots R1 - R4; you can install up to four RFD Cards in a WCS-2.
• WCS-4: Slots R1 - R8; you can install up to eight RFD Cards in a WCS-4.
The following graphic and table identify the RFD Card components.
CAP M and CAP H APs require the use of RFD Card PN 7633229-01 or higher, or an RFD HB Card PN
7841277-00. RFD Card PN 7633229-03, which has been updated with new subcomponents to prevent
material delays or obsolescence, requires ERA SW V2.8.0.400 or SW V2.8.2 or higher.
APs that support TETRA services require RFD Card PN 763229-05. SW V2.8.0.400 or V2.8.2 or higher is
required to use the 7633229-05 card.
RFD Card PN 7841277-00 is required for operating at frequencies between 2700 MHz to 4300 MHz and
operates as low as 1700 MHz. Requires ERA SW V3.0.0 or higher.
