Mount the BCU in a Rack
The BCU is the main controller of the RadioFrame System. The BCU is mounted in a
rack supplied with –48VDC power.
1 Find these items in the BCU shipping container: one BCU, four mounting screws, and
one set of product documentation.
2 Mount the BCU only in an EIA-standard compliant (19”) rack using all 4 screws
provided. Refer to the site documentation for the exact location of the BCU. For safe
operation, follow these guidelines:
• Do not mount the BCU in any orientation other than that specified in the following
illustration.
• Mount the BCU so that both the front and the back are accessible.
• If the mounting holes do not line up, adjust the BCU up or down until the mounting
holes line up.
•
Caution
Do not block the air vents on the sides or rear of the BCU.
3 Plug the BCU into main rack power source (rectifier or PDU).
4 Verify that the BCU is receiving power and that each BCU card is operational.
Each card installed in the front and back of the BCU has two LEDs: Power and
Status. All LEDs should light green.
Note
The Status LED on the top card in the front of the BCU will remain red until the
BCU is connected to a timing source.
