Introduction
About this manual
This chapter describes servicing tasks and provides an
overview of safe working practices to be used when
servicing the server unit.
Servicing policy
Generally, a ‘board replacement’ policy is implemented on
the server unit. The service engineer WILL NOT normally
be expected to change board components (ICs, LEDs,
resistors, etc.). The information and instructions given in
this manual reflect this policy.
A list of all the serviceable parts, and exploded views of
the server unit are given in
Chapter 8, Spare Parts .
Servicing tasks
An on-site service engineer may be asked to do the
following servicing asks:
• Perform regular and essential maintenance - see Chapter
7, Maintenance .
• Troubleshoot apparent fault symptoms - see Chapter 5,
Troubleshooting .
• Order replacement parts - see Chapter 8, Spare Parts .
• Replace any faulty parts - see Chapter 6, Parts
Replacement .
• Use diagnostic and testing utilities to help identify
problems, asses the status of the server and test the
functionality of replaced parts - see
Chapter 3, Utilities .
Notifying clients of interruptions
Servicing tasks should, in general, be performed, with
consideration for the HDXchange clients and, where
possible, without interruption to the normal operation of
the HDXchange system.
Some servicing tasks, however, will require that clients be
disconnected or shut down while internal parts are
replaced or system tests carried out, thereby interrupting
the day-to-day operation of HDXchange.
• Always ensure the minimum of interruption to clients
and users of the HDXchange system. Ensure that all
possible servicing or corrective actions have been
attempted prior to shutting down the server or taking it
off-line.
• Always notify clients prior to shutting down the server
or interrupting the operation of the HDXchange system.
Give as much advanced warning as possible and allow
clients/users to back-up or save their work.
• Always keep clients and users up-to-date with
progress and estimates of how long repairs will take.
Give regular bulletins if parts have to be ordered and
fitted.
• Always notify clients when the system is back on-line .
Ensure that any other relevant administrators, office
staff, etc., are also notified that the HDXchange system
is working and available.
