Chapter 2
Diagnostic Procedures
All of the procedures in this chapter require an attached
video device.
Once an FRX4000 is operational, much diagnostic information is
available through menu-level operations (described in the Netlink
FRX4000/FRX6000 User Guide). However, some problems might
arise that do not readily identify themselves through system error
messages or obvious changes in operation. This chapter describes the
procedures for verifying correct configuration and operation of an
FRX4000. It also provides some guidelines for pursuing a solution if
there is a problem.
When an FRX4000 is switched on, the following should occur:
●
The fan(s) and the power light on the front panel will come on.
●
As the software is loaded, messages will be displayed.
If there are problems during boot-up, error messages will be dis-
played, and the process will continue after the message has been dis-
played for a short time (so watch the screen carefully).
Once the software has correctly loaded, a screen similar to the fol-
lowing will be displayed.
