6 MAINTENANCE
6.1
GENERAL
This section addresses repeater faults, fault identification, fault troubleshooting,
removal and replacement of faulty item(s), and final system testing.
6.2
MAINTENANCE PHILOSOPHY
Repeater maintenance is limited to removal and replacement of least replaceable
units (SPU, HPA, RF Coupler, RF Detector(s) and fixed hardware components such as
air filter, fans, and cables) and modification of GUI screen parameters. The user is not
authorized to attempt repair of any LRU. Repair or replacement of any other compo-
nents, such as the PDU, Band Pass Filter, or internal heater requires replacement of
the entire repeater assembly
. Prior to shipping a repeater back to Alcatel-Lucent, con-
tact the Customer Technical Assistance Center (CTAC) to discuss the problem. See
CTAC contact instructions in the Front Matter section of this manual.
6.3
TEST EQUIPMENT
The only test equipment required is a PC.
6.4
SPECIAL TOOLS
Two special wrenches are required to perform maintenance on the HPA and the RF
Coupler.
•
HPA RF CONNECTOR WRENCH:
1 1/4-inch open-end, overall length not to exceed four inches. Maximum
thickness 1/2 inch.
•
RF COUPLER WRENCH:
1 1/8-inch open-end, overall length not to exceed five inches. Maximum
thickness 1/8 inch.
6.5
PREVENTIVE MAINTENANCE
The only required scheduled preventive maintenance is for the rear door air filter
assembly. As a general rule, it is recommended replacing the air filter every 6 months
under normal conditions or every 3 months in dusty environments. Under extremely
dusty conditions or in a windy environment near open areas with loose blowing sand/
dirt, it is recommended that filters be inspected more frequently and adjusting
replacement intervals as deemed necessary.
6.6
TROUBLESHOOTING OVERVIEW
Troubleshooting can be performed remotely and locally as described in the following
paragraphs.
6.6.1
Remote Troubleshooting Overview
Remote troubleshooting is performed at the NMC by an operator using the GUI screens.
When the cause of the fault is identified, the user determines if the fault can be cor-
rected from the NMC. If not, a maintenance technician is dispatched to the repeater site.

DTR-0200-SA-SIRIUS Issue 1, March 2008
6-2
6.6.2
Local Troubleshooting Overview
Local troubleshooting is performed at the repeater site by a dispatched technician
using a PC, GUI screens (or CLI), and external test equipment. When the fault is cor-
rected, the technician follows on with a system test. When satisfied that the repeater
is operating correctly
, coordination between the technician and the NMC operator
returns the repeater back to the remote operating condition and broadcast mode.
6.7
REPEATER ALARM INDICATORS
Alarms are indicated on GUI Status screens, GUI Alarms screens, and front panel
LEDs.
Refer to Appendix D, Alarm Descriptions, Causes, and Corrections
.
6.8
TROUBLESHOOTING PROCEDURES
6.8.1
Remote Troubleshooting/Repair Procedures
• Upon receipt of an alert via the repeater site TELCO line, NMC personnel
will evaluate the indicated problem(s). Refer to the Operations section for
instructions on use of the GUI.
• Access the GUI
• View the Alarms screens for indicated problem identification.
• View the Status screens for additional information.
• If it is determined that the problem(s) can be corrected remotely, access the
necessary GUI screens and correct as required.
• If it is determined that the problem(s) cannot be corrected from the NMC,
take the necessary steps to dispatch a technician to the repeater site to
perform local maintenance.
6.8.2
Local Troubleshooting/Repair Procedures
When indicated cautionary statements are adhered to by the technician during
maintenance, the equipment is unlikely to present a hazard to the technician or the
structure.
The front and rear doors of the repeater cabinet are secured by
draw latches and captive locking screws. There are two latches
and two locking screws on the cabinet front door and two latches
and one locking screw on the cabinet rear door (see figure 6-1). It is
imperative that opening and/or closing of these doors be done in
the provided sequence. Failure to follow the sequence could result
in door warping or bending and render the cabinet water protec-
tion system invalid.

Opening the Door – first release the captive locking screw(s) then
undo the draw latches.
Closing the Door – first secure the draw latches then tighten the
captive locking screw(s).

NMC coordination must be accomplished prior to repeater being
switched to Local operating condition. This will prevent conflict-
ing actions between the NMC and on-site operator(s) and preclude
possible personal injury and/or equipment damage.
• Switch the repeater to the Local operating condition.
• Connect the PC to a repeater Ethernet (LAN) connector on the back panel
of the Controller (or to the SPU front panel RS-232 connector for CLI if an
active LAN connector is not available).
• View the SPU front panel indicators.
• Access GUI (or CLI screens).
• Use the Alarms and Status
GUI
in conjunction with the SPU front panel
indications to help identify problem(s).
• Refer to Appendix D, “Alarm Descriptions, Causes, and Suggested
Responses”, for procedures to correct problems.
• Access the GUI screens and enter changes as required.
• Remove and replace components if required.
• Major unit replacement requires parameter updating.
• Run repeater test on completion of troubleshooting/repair.
• Coordinate with the NMC and return repeater to the Remote operating
condition.
When working in the vicinity of fans (under repeater roof or
replacing air filter on repeater back door), power to fans must be
removed.

Chart 3 Remove and Replace RF Detector(s)
Main power to repeater must be off.
Prior to removal of detector(s), tag each to identify which is the forward RF
detector and which is the reflected RF detector. Failure to install detectors
correctly will cause the wrong feedback signals to be transmitted to the
main controller. This in turn will cause HPA power problems and inaccu-
rate power readings.

CALARM DESCRIPTION, LIKELY CAUSE, AND SUGGESTED RESPONSE
Alarms are listed alphabetically by alarm names as they appear on the GUI
Alarm screen
Deviating above a positive or below a negative temperature threshold will
cause an alarm as indicated in Table C-1. Following are the temperature
thresholds for the repeater:
C.1
HPA DEFAULT TEMPERATURE THRESHOLD
• HPA Warning Low Temperature . . . . . . . . . . . . . . . . . . . . . -18˚C
• HPA Warning High Temperature . . . . . . . . . . . . . . . . . . . . +78˚C
• HPA Critical Low Temperature. . . . . . . . . . . . . . . . . . . . . . -30˚C
• HPA Critical High Temperature . . . . . . . . . . . . . . . . . . . . . +82˚C
C.2
HPA COLD START OPERATING TEMPERATURE THRESHOLD
This value is in the HPA Controller firmware and cannot be changed by the
operator. When the repeater is cold started below -18˚C in Broadcast or Test
mode, HPA DC power will be on but RF will be off until temperature is
equal to or higher than -18˚C.
• HPA Cold Start Operating Temperature: . . . . . . . . . . . . . . -18˚C
C.3
