Maintenance Manual
1. INTRODUCTION
This document describes the maintenance of the SSS1100 / 1100+ and SSS2
cabinets as a post-integration function check. This document is to be used together
with [8] and [9]. This document is intended for the service personnel of the network
operator.
The SSS1100 / 1100+ and SSS2 cabinets are designed to work in conjunction with
a Nokia DE / DF 34 Base Station and contain three main functions. They supply
DC power to the Base Station, house a battery backup system and provide space
and DC power for customer chosen and supplied RLEs.
The task of the maintenance is to check the functions of the SSS1100 / 1100+ and
SSS2 and its inventory periodically.
The maintenance is to be undertaken every six months using [3].
In special cases, e.g. dusty ambient conditions, shorter maintenance intervals may
be required. This should be decided at the discretion of Nokia and the customer.
1.1.
Fault reporting
All damage, failures and faults should be corrected, wherever possible, during
installation of the cabinet, and reported to Nokia using a Failure Report Form
provided by the Customer Service Centre (CSC).
Update the site folder after maintenance measures or modifications.

When doing maintenance work on the SSS1100 / 1100+ and SSS2 cabinet with the
