TROUBLESHOOTING
This section provides troubleshooting guide-
lines to use for solving problems you may
encounter servicing the E4 Series II sys-
tems.
♦
E4 Series II hardware indicators
•
Normal operation
These are the indications of normal opera-
tion.
♦
System fault
A red SYSTEM STATUS LED indicates that
the system received an error from one of its
many internal components. A red SYSTEM
STATUS LED after AC power is switched on
may be caused by:
• A Power-On Self-Test failure
• A DSP error
• The DSP is offline
To determine the severity of the error, cycle
the unit’s power off and back on again. If the
SYSTEM STATUS indicator is now off, the
system has logged an error, but is still
operational.
When you check the error log using the
Installer™ software you can identify the
cause of the error, and determine an appro-
priate solution.
