General maintenance overview
In this chapter
This chapter contains the procedures for the general maintenance of a
Horizon
macro outdoor BTS. There is no schedule for routine maintenance on
Horizon
macro outdoor equipment. General maintenance procedures are to be
carried out during site visits in response to alarms (as required), or at intervals
deemed appropriate by the customer, (determined by the type of installation, its
use and operation, the frequency of maintenance and the external influences to
which it is subjected).
NOTE
Since a Horizon macro BTS operates as part of a network,
the procedures in this chapter must be performed in
conjunction with the relevant network procedures in the
associated OMC-R manuals.
It is recommended that the following general maintenance procedures are
carried out for Horizon
macro outdoor installations:
 Ensure that cabinet air inlets and exhaust grilles are not blocked.
 Check normal operation, including TMS fans. Also check cable integrity
and the condition of all connections.
 Check battery backup operation and battery capacity.
 Inspect general mechanical condition and finish of the cabinets.
 Inspect locks, handles and hinges and door seals. Lubricate if required.
Reporting
faulty devices
During general maintenance and FRU replacement procedures, it may be
possible to identify signs of damage that might indicate a problem that could
repeat, cause additional damage, or be a symptom of a failure elsewhere.
Analysis of the problem may identify common faults and make corrective action
possible.
Whenever a safety issue arises:
 Inform the OMC-R that an equipment safety problem has been identified.
 Make the equipment concerned safe, for example, by removing power.
 Make no further attempt to tamper with the equipment.
 Report the problem directly to GSM Customer Network Resolution Centre
[phone] (telephone) and follow up with a written report by fax
[phone] (fax).
 Collect evidence from the equipment under the guidance of the Customer
Network Resolution Centre.
 Seek local office advice.
