Maintenance Interface

A maintenance interface area is located on the bottom of the RU. This area is sealed by maintenance cover for
protection against water ingress. The maintenance window cover can be opened manually using a Torx
screwdriver. When not in use, the maintenance window cover must be fastened with screws torqued to 1.8 Nm.
The RU maintenance window has three LEDs that indicate the status of the RU for example, operation, failure
(machine status) and eCPRI link.
■ One Fault, Red color
■ One Operational, Green color
■ One Interfaces, Green color (one corresponding to eCPRI port)
The software controls the on/off and blinking LEDs according to the status of the RU.
