4.3.1 Audible Alarm Mute
When the Audible Alarm sounds, it may be muted by pressing the Alarm Mute push-button until a double beep is
heard (approximately 1 second). The Alarm Mute push-button is located beneath the indicators on the Operator
Panel (see Figure 4–1 ).
When the alarm is muted it will continue to sound with short intermittent bleeps to indicate that a problem still
exists, It will be silenced when all problems are cleared. (See also Thermal Shutdown states, Section 4.5.5 ).
4.4 Test Mode
A Test Mode is available whenever there are no faults present within the sub-system. In this mode the Amber and
Green LEDs on each of the drive carrier modules are flashed on and off in sequence.
To Activate Test Mode (with no other faults present)
Press the Alarm Mute push-button until a double beep is heard. The LEDs will then flash until reset, either by
pressing the Alarm Mute push-button again or if any actual fault occurs.
4.5 Troubleshooting
The following sections describe common problems, with possible solutions, which can occur with your SS-1200-
FCAL system.
4.5.1 System Faults
Note See also Section 4.5.5 .
Symptom Cause Action
1 The SYSTEM LED will
illuminate AMBER
2 Audible Alarm sound
The ESI processor has detected
an internal fault (e.g. failure of
an internal communications
path)
1 Check for other AMBER LED
indications on the Power Supply/Cooling
modules. If there is a PSU error present
there may be a communications problem
with that Power Supply/Cooling module.
Remove and then re-fit the module, if the
problem persists then change the module.
2 Check for other AMBER LED
indications on the drives carriers. If none
are evident then there may either be an
ESI processor problem or a Backplane
problem.
3 Change the ESI/Ops Panel module (see
4.9.2 ).
