Technical Data & Troubleshooting
6.1 Overview
A consequence of modern surface-mount construction is that it is frequently no longer possible
for local repairs to be made. Special and expensive equipment is required to change parts. As
well, today’s equipment is very complicated and requires repair technicians to have detailed
experience and training, and have access to high-end test equipment.
At the same time, the advent of overnight delivery services means that equipment can be
returned to the factory for quick turn-around repair. erefore, we do not expect you to fix this
unit at the component level, and we do not include schematics of the unit in the manual. Upon
request, our support staff can fax or mail you the needed schematic. Please see the first pages of
this manual for proper procedures on returning units for repair.
ere is the possibility, however, that you could repair the unit by swapping subsystems such as
plug-in modules or power supplies. e Telos customer support crew is standing-by to assist
with this, if you need it.
6.2 System Software & Firmware
Viewing Version Information
To assist with troubleshooting, Telos customer support may ask you to provide some software
version numbers. ere are two major software components to the system:
System software – is is the software that can be updated by downloading new software.
♦
Firmware – is code is analogous to a bootstrap loader and contains certain critical low- ♦
level software. is information can only be updated or changed at the factory. It is stored
in a partition of the non-volatile memory on the motherboard.
e software version and software build date can be determined from the start-up screen. e
software version and software build-date are shown. (e build date is not the date your Nx12
was made.)
6.3 General Troubleshooting
Thinking about Problem Solving
Despite best intentions, something could always go wrong. Sometimes troubleshooting a balky
set-up can make even the toughest engineer a Maalox and Rogaine addict.
