To run a diagnostic program, enter the corresponding letter or number. There
are several sub-menus to cover the different options. The following table lists
keys that control the basic operation of the diagnostics.
Diagnostics are designed to be used with all models of the router, and therefore
some instances of particular tests are not appropriate for some models. A
reasonable level of understanding of the system structure is needed to operate
diagnostics and interpret the results. Diagnostics only require the base CPU
board to be installed in the system.
To restore the router to normal operation, perform a restart by switching its
power switch (rear panel) OFF and ON.
This hardware manual is not intended as a guide to diagnostics. Diagnostics are
designed to be run by service personnel only. For more information, contact your
authorised Allied Telesyn distributor or reseller.
Lithium battery replacement
The routers have a replaceable lithium battery. If replacing the battery, use a 3V
lithium button cell, type CR2032 or equivalent.
The battery should be replaced when the router:
• has been in storage for more than two years
• has only been powered up intermittently over a two year period
• loses its time setting
Batteries should be replaced by authorised service personnel only.
Unauthorised opening of the router lid may cause danger of injury from electric
shock, damage to the router, and invalidation of the product warranty.
