components,
which includes the ERA WCS-2, WCS-4, -48Vdc WCS-2, -48Vdc WCS-4, and e-POI Subracks and their cards or
modules, and the Power Supply Subrack and its 12 Vdc and 57 Vdc Rectifier Modules. Table 1 identifies the
ERA hardware that this installation guide supports.

Component Description
WCS Subracks and Cards
WCS-4 Subrack The WCS-4 Subrack is configured in the GUI as a Classic CAN, Switching CAN, WIN, or TEN.
The WCS-4 (7635442-xx) is powered by the ERA AC to DC PSU subrack and power
modules. The -48Vdc WCS-4 (7844068-xx) is powered by an external -48 Vdc power
supply.
WCS-2 Subrack The WCS-2 Subrack is configured in the GUI as a Classic CAN, Switching CAN, WIN, or TEN.
The WCS-2 (7635443-xx) is powered by the ERA AC to DC PSU subrack and power
modules. The -48Vdc WCS-2 (7844067-xx) is powered by an external -48 Vdc power
supply.
Fan Module The factory installed Fan Tray Modules cool a WCS Subrack and all of its cards.
See Figure 17 on page 79 Fan Filter Air Filter Modules are installed in the left side of the WCS Subrack to prevent dust and
other particulates from circulating into the WCS Subrack.
System User Interface
(SUI) Card
The SUI Card provides local and LAN Ethernet connections and a USB port.
RF Donor (RFD) Card
RF Donor (RFD) HB Card
The RFD Card is the interface for RF signals between the RF source (such as the BTS,
eNodeB or e-POI) and a Classic CAN and WINs.
RFD Card PN 7633229-0x is for frequencies between 380 MHz and 2700 MHz. RFD HB
Card PN 7841277-00 is for frequencies between 2700 MHz and 4300 MHz (and can be
used down to 1700 MHz).
Note that CAP M and CAP H APs require the use of RFD Card PN 7633229-01 or higher, or
an RFD HB or a CDD card. APs that support TETRA services require RFD Card PN
7633229-05 or higher or a CDD card.
Optical Transport (OPT)
Card
The OPT Card provides a 10 Gbps fiber connection between a Switching CAN, TENs, and
WINs; and between a Classic CAN and TENs and Fiber APs. Each OPT Card supports up to
four SFP+ transceivers for device connections. New OPT Card 7642123-01 requires ERA
V2.8.0 or higher software.
Copper Transport (CAT)
Card
The CAT Card provides 10 Gbps Cat6A connections between a Classic CAN and TENs and
UAPs or Copper CAT Ls.
CAT Cards also supply the remote power over Cat6A to the UAPs
or Copper CAT Ls. At least one 57 Vdc Module is required to use a CAT Card.
Auxiliary Unit Transport
(AUT) Card
The AUT Card provides a 1 Gbps pass-through connection between a Classic CAN and
TENs and APs for WiFi, IP cameras, or other Ethernet devices.
CPRI Digital Donor (CDD)
Card
The CDD Card provides a digital CPRI interface between a Nokia BBU and a Classic CAN or
WIN.
Power Supply Unit and Power Modules
Power Supply Unit (PSU) The PSU can house up to two 12 Vdc Power Modules and two 57 Vdc Power Modules,
which supply power to WCS Subracks, APs, and connected devices.
12 Vdc Power Module A 120/240 Vac to 12 Vdc module plugs into the Power Supply Subrack to provide 12 Vdc
power to WCS Subracks and e-POI Subracks.
57 Vdc Power Module A 120/240 Vac to 57 Vdc Module plugs into the Power Supply Subrack to provide remote
power over Cat6A to connected APs and devices connected to the APs.
e-POI Subrack and Cards
e-POI Subrack The e-POI Subrack supports up to eight e-POI RF Modules (RFMs) and one Interface Card
(IFC); ships with the IFC factory-installed.
