Storing RRHs in non-powered state

Purpose

Important! Alcatel-Lucent does not provide support for RRHs that have been left

non-powered for an extended period of time and not stored in an environmentally-

controlled space. The Alcatel-Lucent Design Team provides the following guidelines

to minimize the build-up of moisture inside RRHs that must remain in the

non-powered state for an extended period of time.

This section describes how to properly store RRHs that have been delivered to an

installation site but have not been yet installed. The main concern with non-powered

cabinets is condensation inside the cabinet, which can result in corrosion or electrical

shorts. The location and length of storage time determine the severity of the problem.

These guidelines include prevention and drying steps.

Moisture problem prevention

To prevent moisture from collecting inside non-powered RRHs that are in storage, all

openings and connectors must be tightly sealed. The units should also be covered with a

waterproof tarp. The tarp should be sealed with duct tape. A desiccant packet should be

placed under the tarp to absorb moisture. The amount of desiccant is related to storage

time and to size of the unit. A visual check should be made to check for condensation

after uncovering the tarp.

Additional storage requirements

After performing the procedures above, ensure that the following steps are taken:

• The cabinet must be properly grounded.

• RF cables should not be connected to the RRH.

• Any connectors must be sealed with watertight plugs.

• All holes must be plugged with watertight plugs.
