4-1Remote Annex 4000 Hardware Installation Guide
Chapter 4 Troubleshooting Procedures
The Remote Annex 4000’s front panel has six system LEDs, a Test
LED, and status LEDs. The system LEDs are labeled Power, Unit, Net,
Attn, Load, and Active. The status LEDs are numbered one
through eight.
The system LEDs provide information about normal operations and
about problems that occur. Use these LEDs and the ROM Monitor
commands to diagnose problems.
The status LEDs display port activity during normal operations; each
LED supports nine ports. When the Remote Annex 4000 encounters
a problem or an internal error condition, these LEDs display error
information.
If an error occurs, save the status of these LEDs. Technical
support personnel can use this information to
diagnose problems.
During power-up and booting, it is more complicated to diagnose
problems because they can originate in the Remote Annex 4000, the
transceiver, the Ethernet, or the load server host. However, the LEDs
provide both a progress report and an error display to assist you in
troubleshooting.
This chapter describes power-up and booting, troubleshooting
during booting, and the file created from a Remote Annex 4000 dump.
