8TIMING AND ALARM CONTROLLER
MANAGEMENT
The Cuda 12000 utilizes an external fan tray for cooling and obtains power
from an external power source. Fault management features on the Cuda
12000 for the fan tray and power source are:
■The Timing and Alarms Controller (TAC) that resides on the Management
module. TAC provides alarm processing for detection of faults associated
with fan tray and power supply auxiliary devices.
■Software reporting functions that allow you to configure the reporting of
fault conditions. Fault reporting alerts you to fault conditions as they
arise, so you may take action prior to a loss of operation, or know when
the power source and cooling capability is compromised.
■DB-15 connectors on the rear panel of the Cuda 12000 that allow you to
send specific types of alarm signals to notify an auxiliary device that a
fault occurred.
This chapter provides information and procedures for configuring the
monitoring and reporting of power and fan tray fault conditions and
