WCS-2 and WCS-4 Subrack Overview
CDD Card CPRI Port LEDs
A CDD Card has six LEDs that correspond to its six CPRI ports, as shown in the following graphic and table.
LED Color
Affected LEDs
State
Off
All six
No power to the CDD Card. If this state is not expected, do the following in the order presented:
1 Verify that the CAN is powered on (the CAN powers the CDD).
2 Verify that the CDD Card is enabled; the default setting is
Off
(disabled) and must be manually set to
On
(enabled).
3 Reseat the CDD Card in its slot or move it to another slot to make sure there is firm connectivity with
the WCS Subrack.
Flashing Red
All six
Can be any of the following:
• External Power Supply Failure—board power failure.
• There is a boot error.
CPRI port specific • CPRI port is not communicating with the WCS/CAN.
Solid Red
All six
Can be any of the following:
• CDD Card is receiving power, but its FPGA has not loaded.
• CDD Card is in Bootloader mode and its RAM test failed.
CPRI port specific • An SFP Module is not present in the CPRI port, but the CDD Card is configured via the ERA software.
Verify that there is an SFP Module installed and is firmly seated in the CPRI port.
Flashing Amber All six
Firmware download is in process. Note that this process includes matching the CDD Card firmware to
the ERA Software Version running on the CAN in which the CDD Card is being installed. If the firmware
on the CDD Card is different from the CAN, it will take slightly longer to download the firmware to the
CDD Card. Wait until the LEDs are solid amber before configuring the CDD Card.
Solid Amber
All six
Can be any of the following:
• All firmware updates have been pushed to each port and the CDD Card is ready to be configured.
• The port has been configured from the DAS side, but the BBU has not provided a carrier yet.
Flashing Green CPRI port specific The BBU has provided a carrier, but the Signal Set has not yet been created and linked to an AP.
Solid Green
CPRI port specific Port is configured for a Carrier and the Signal Set is being distributed to an AP.
