System LEDs
The Remote Annex 2000’s front panel has six system LEDs, a Test
LED, and eight 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
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 one or two ports. When the Remote Annex 2000
encounters a problem or an internal error condition, these LEDs flash
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 2000, 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.
