POWER SUPPLY UNIT SUBRACK AND RECTIFIER MODULES
The following sections describe the ERA Power Supply Subrack and the 12 Vdc and 57 Vdc Rectifier Modules.
Power Supply Unit Subrack
The ERA Power Supply Unit (PSU) Subrack (PN 7693531-xx) can house two 12 Vdc Rectifier Modules and
two 57 Vdc Rectifier Modules that provide power to the WCS Subracks, APs, and connected devices.
The PSU ships with the output DC cables already attached. The signal cable for connecting the PSU to the
chassis is also provided and must be connected prior to powering on the unit. However, you can order input
AC cables that are specific to the region in which the ERA system is installed, as shown in Table 3. Contact your
local CommScope sales representative for assistance in ordering an AC Power Cable.
The 12 and 57 Vdc Rectifier Modules have an operating temperature range of -10 to +55 °C (+14 to +131 °F).
The Power Supply subrack and rectifier modules supply power to the WCS-2 (7635443-xx) and WCS-4
(7635442-xx) subracks. The power for the -48 Vdc WCS-2 (7844067-xx) and WCS-4 (7844068-xx) subracks
is supplied by external -48 Vdc power supplies.
