Error Indications and Countermeasures

Overview
This switcher performs self-diagnosis testing when
you turn the power on, reset the switcher, and at
regular intervals during operations. If the self-
diagnosis test detects an error, the status indicator
lights, and information about the error is output to the
terminal. The information about the error is also
output to the host computer of the ISR system if this
switcher is connected to the system. You can simply
determine the origination of the error through the 2-
digit error code shown on the ERROR NO. indicator
on the CPU-149 board. The errors possibly displayed
on the switcher and their respective countermeasures
are shown in the table below.
Refer to the maintenance manual for information
concerning the error codes displayed on the ERROR NO.
