Chapter 2-Diagnostic Procedures - Cabletron Systems FRX6000 Maintenance Manual

All of the procedures in this chapter require an attached
VGA monitor. You should also have a diagnostic diskette
(such as CheckIt®) and a bootable 1.4 MB blank diskette,
to analyze the system configuration.
Once an FRX6000 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
FRX6000. It also provides some guidelines for pursuing a solution if
there is a problem.
When an FRX6000 is switched on, the following should occur:
The fan(s) and the power light on the front panel will come on.
BIOS identifying information will be displayed.
There will be a short beep as memory is tested, and the screen
will display the memory being counted.
Each disk drive's access light will come on as the disks are
searched for the necessary DOS boot files.
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).
