IPC-616 User's Manual

Chapter 3 Fault-resilient Functions

3.1 Introduction

A fault-resilient IPC has a fault detection and alarm notification system. The IPC-616 monitors its own

status. See Figures 3-1 and 3-2 below. When a malfunction occurs, the unit alerts users of the need for

maintenance.

3.2 Fault Detection and Alarm Notification

The IPC-616 monitors system hardware for power failure, fan failure and overheating within the

chassis. Fault conditions are:

Power failure: Either the backplane power source (+5 V, +12 V, +3.3 V, -5 V, -12 V) or redundant

power module fails

Fan failure: Either of the two cooling fans fails

Overheating: The chassis' internal temperature has reached or exceeds the user's preset maximum safe

temperature

Once a problem is detected, an audible alarm activates and an LED alarm indicator (located on the

front door) changes color from green to red.
